Golden Minerals Provides Update on Drill Campaign at El Quevar


GOLDEN, CO--(Marketwire - September 27, 2010) - Golden Minerals Company (NYSE Amex: AUMN) (TSX: AUM) ("Golden Minerals" or "the Company") today provided an update on the drill campaign at the El Quevar project. The El Quevar project, which is 100% controlled by Golden Minerals, is located in the Salta Province of northwestern Argentina.

The Company currently has three drills operating at the El Quevar project, with a fourth drill en route to the project. The drill campaign is focused on following up on the results reported from a drill hole recently completed at the Mani target, located 500 meters south of the main Yaxtché deposit, and from a hole drilled on the eastern portion of the Yaxtché deposit. Drilling is also planned for the Carmen target, located 300 meters north of the Yaxtché deposit. In addition, drilling is underway on the west side of post mineral cover at the Yaxtché deposit to test the potential western extension of the deposit. When the fourth drill arrives, additional infill drilling will resume on the main zone of the Yaxtché deposit to provide more detailed information about the mineralization, including drilling to offset certain drill holes, including the recently reported drill hole QVD-211, which intersected 146 meters of mineralization averaging 317 grams per tonne of silver. The offset drilling should help to confirm the size and shape of these intercepts.

Drill hole QVD-220 recently reported for the Mani target contained a five meter intercept of 515 grams per tonne silver and a two meter intercept of 411 grams per tonne silver. Drill hole QVD-217, located on the eastern portion of the Yaxtché deposit, where limited drilling has occurred to date, reported a two meter intercept of 970 grams per tonne silver and a two meter intercept of 489 grams per tonne silver. As previously reported, this intercept suggests that the main Yaxtché deposit may extend further east than previously believed. Preliminary results from drill hole QVD-221, which is the first hole of a planned ten hole drill program on the west side of the post mineral cover at the Yaxtché deposit, encountered a zone of strong silicification containing lead mineralization but no silver mineralization, similar to the style of mineralization found in holes peripheral to the main zone of mineralization at the Yaxtché deposit. Previous drilling at the Carmen target included drill hole QVD-139, an angle hole which intersected four meters averaging 200 grams per tonne of silver and 1.98 grams per tonne of gold.

The Yaxtché deposit is one of 11 targets currently identified at the El Quevar project. In addition to further drill testing of the targets described above, drilling is planned for the Quevar Norte targets, where an initial six hole drill program was previously completed on three targets, with three of the six holes intersecting silver mineralization of greater than 100 grams per tonne, including Hole QND-002, which averaged 1,289 grams per tonne over an intercept of 28 meters at the Sharon target. The Quevar Norte targets are located approximately three kilometers north of the Yaxtché deposit.

As previously reported, the Company has deferred completion of the final feasibility study until additional drilling has been completed to further define the extent of the deposit.

A drill hole location map and listing of all drill intercepts for the holes at El Quevar for which the Company has received and verified results are available at http://www.goldenminerals.com/.

Review by Qualified Person, Quality Control and Reports

Results of the Company's drilling program have been reviewed, verified, and compiled under the direction of the Company's Senior Vice President of Exploration, Robert Blakestad, M.Sc., P.Geo, L.P.G., a Qualified Person for the purpose of NI 43-101. Mr. Blakestad has over 35 years of mineral exploration experience, is a Professional Geoscientist registered in Nova Scotia and a Licensed Professional Geologist in the state of Washington.

Drill intercept lengths are down-hole lengths reflecting apparent widths of mineralization with true widths estimated to be from 90% to 95% of the reported down-hole lengths.

To ensure reliable sample results, Golden Minerals uses a quality assurance/quality control program that monitors the chain-of-custody of samples and includes the insertion of blanks, duplicates, and certified reference standards in each batch of samples. Core is photographed and sawn in half with one half retained in a secured facility for verification purposes. Sample preparation (crushing and pulverizing) is performed at an independent ISO 9001:2001 certified laboratory in Mendoza, Argentina. Prepared samples are direct-shipped to ISO 9001:2001 certified laboratories in Santiago, Chile or Vancouver, B.C. Pulp splits of mineralized intervals are re-assayed at certified independent referee laboratories in Chile and Canada.

Latin American Minerals Inc. Signs Joint Venture Agreement with VotorantimMetais for Rio Tendal Massive Sulphide Project


TORONTO, ONTARIO--(Marketwire - Sept. 27, 2010) - Latin American Minerals Inc. (TSX VENTURE:LAT)('Latin American') and VotorantimMetais Argentina SA ('Votorantim') have signed an agreement whereby Latin American has granted to Votorantim the right to acquire an initial 51% interest in the Tendal Mineral Concessions in La Rioja Province, Argentina by funding USD 4,500,000 in exploration development over a three year joint venture period.

The agreement also stipulates that Votorantim has an additional option to earn a 19% additional interest in the property by solely funding development to the completion of the feasibility study during another period of three years. Votorantim has 60 days from the exercise date of the initial option to elect this additional interest.

Details of the agreement stipulate a minimum exploration expenditure of USD 500,000 in the first year of the agreement and, in addition to the exploration expenditures, USD 50,000 annual cash payments to Latin American during the JV period.

Votorantim is a subsidiary of VotorantimMetais, the largest producer of zinc in Latin America and one of the ten largest worldwide. VotorantimMetais' activity in the zinc market began in 1956 in Minas Gerais, Brazil. Votorantim has enjoyed excellent national and international growth featuring the key acquisitions of the Juiz de Fora Zinc Refinery in 2002; the Cajamarquilla Zinc Refinery in Peru in 2004; a 51% interest in the Milpo Mining Company, the fourth largest Peruvian zinc miner (2005/2010) and the acquisition of US Zinc in 2007. The Mineral Exploration division of VotorantimMetais is actively exploring in Brazil, Canada, Mexico, Colombia, Peru and Argentina.

Latin American Minerals holds a 100% interest in the six Tendal mineral concessions, which comprise two land parcels totaling 36,488 hectares. The Tendal zinc, copper, lead and silver property is located in the province of La Rioja in northwestern Argentina and is accessible by all-season gravel road.

At Tendal, massive sulphides outcrop on surface in the Espinal Formation and in the Rio Bonete Formation. The sulphides have suffered deformation but are concordant to schistosity and major lithologic units indicating syngenetic deposition with the sedimentary host units.

Massive sulphides outcrop in the Espinal Formation on surface for over 2 km extent, in stacked lenses up to 18m thick extending along an 80m zone. Saw-cut channel samples along the massive sulphide bodies confirm zinc mineralization on surface extending for up to 18.5 meters true width with 4.28% Zn. Drill hole results confirm the extension of the mineralization at depth with a 4.41m intersection having 4.49% Zn.

Massive lead-zinc sulphides in the Rio Bonete Formation have a smaller footprint on surface, extending 400m in length along two zones of 8m width. Trench samples in these mineralized zones yielded up to 8m width of 8% Pb and 3% Zn. Drill holes yielded 4m with 5.18% Zn and 3.15% Pb including 1.7m with 9.18% Zn and 3.18% Pb.

Latin American has performed 2079m of diamond drilling in the district to date. The extension of mineralization found on surface and the promising results at depth show that the mineral camp has exploration potential for a major new zinc discovery in Argentina.

Miles Rideout, President of Latin American Minerals stated that 'We are extremely pleased that the preeminent South American zinc producer will lead development of the Tendal Project.'

LAT is a mineral exploration company focused on the acquisition and development of base and precious metals projects in under-explored but highly prospective countries of Latin America.

Rodinia Lithium Inc.'s Auger Drilling Extends Near Surface High-Grade Lithium-Potash Zone 1.5 km at Salar de Diablillos


- Exploration Program Continues to Deliver Positive Results

- Auger Drill Program has Expanded the High-Grade Nucleus Another 1.5 km on Strike

- Entire Sampled Salar is Mineralized Averaging 680 mg/L Lithium, 7,400 mg/L Potassium, and 669 mg/L Boron

- Salar Nucleus Averaging 845 mg/L Lithium, 9,092 mg/L Potassium, and 762 mg/L Boron

- Auger Results Are Encouraging for the Ongoing Reverse Circulation Discovery Drill Program

TORONTO, ONTARIO--(Marketwire - Sept. 24, 2010) - Rodinia Lithium Inc. ("Rodinia" or the "Company") (TSX VENTURE:RM)(OTCQX:RDNAF), is pleased to report further sample results from its auger drill exploration program on its Salar de Diablillos lithium-brine project in Salta, Argentina ("Diablillos" or the "Salar"). The completion of an additional 38 sample holes has extended the previously defined 2.5 km by 4.0 km high-grade lithium-potash zone near surface by an additional 1.5 km along strike (see Press Release dated May 26, 2010 for additional details on the original high-grade zone definition).

William Randall, President and CEO of Rodinia, commented "It is encouraging that these additional auger drill holes have intersected grades similar to the previous auger drilling and has extended our high-grade zone an additional 1.5 km. We now have additional areas to target with our ongoing reverse circulation drilling. Coupling these results with drill hole D-RC-01 announced last week, which demonstrated a continuous aquifer to depths of at least 120 metres, provides additional support for the potential to delineate a large scale resource at Diablillos" (see Press Release dated September 17, 2010 for additional details on drill hole D-RC-01).

Based on the completed sampling program of 140 sample holes, the Diablillos auger drill exploration program returned lithium ("Li") values of up to 1,000 milligrams per litre ("mg/L") and potassium ("K") values of up to 11,000 mg/L. Focusing on the nucleus of the Salar, which the Company believes represents the highest probability for production (see Figure 1 below), results returned average Li of 845 mg/L, average K of 9,092 mg/L, and 762 mg/L boron ("B") with favourable magnesium ("Mg") to Li ratio of 3.75 and an attractive sulphate to lithium ratio. Previously reported results for the auger drill program were based on a total of 102 sample holes. The full set of results reinforce the Company's belief that Diablillos may contain high concentrations of lithium, potash and boron and that the project has the potential to become a lithium carbonate producer. The Company remains encouraged by the presence of near-surface brines that contain similar, and in many instances higher, lithium and potash concentrations to other established brine developers in South America.

The completed auger program successfully covered a large portion of the Salar which returned average results of 680 mg/L Li, 7,400 mg/L K, 669 mg/L B, 3.75 Mg:Li, and 10.73 SO4:Li. Certain portions of the salar and its margins could not be sampled due to more extensive overburden material. The auger drill has been modified to be able to successfully penetrate the hard calcium carbonate layers commonly encountered, therefore enabling the additional sampling reported in this press release. In general, lithium values decreased towards the salar margins to the north and south, however drilling will be required to establish whether this trend is consistent at depth. Rodinia has a reverse circulation drill program underway on the Salar, which amongst other things will test the depth of the aquifer, as well as the lithium potential under the areas sampled by the auger drill.

To view Figure 1 – Sampling Contour Map, Salar de Diablillos, please visit the following link: http://media3.marketwire.com/docs/RMimage.jpg

Throughout the auger sampling, Rodinia employed a sampling procedure designed to ensure sample integrity by minimizing contamination of brine samples through the dissolution of overlying sediments and evaporates that may be enriched in lithium. All the holes were drilled to a depth sufficient to ensure penetration of the overlying clay layer, which varies in thickness between one and over three metres. Below the clays, a medium to coarse-grained sand aquifer was encountered containing high-grade lithium brine in its porous space. A historical drill hole in the south eastern margin of the Salar indicates the presence of this aquifer to a vertical depth of at least 75 metres, with material coarsening at depth to a coarse basal conglomerate (SEGEMAR; www.segemar.gov.ar). Rodinia has also recently completed a reverse circulation discovery drill hole, drill hole D-RC-01, which indicated the presence of this aquifer to a vertical depth of at least 120 metres.

Sample integrity was maintained by pushing four inch casing down into the hole and pumping, where possible, the contents of the hole. The hole was then left to refill from the aquifer below, ensuring proper representation of brine geochemistry. This brine was then sampled and decanted before collection in sealed plastic containers that had been previously rinsed in the same brine. All samples were sent to ALS Laboratory Group, Environmental Division, in Fort Collins, CO, USA where Rodinia is sending both its Diablillos and Clayton Valley project samples.

The Project is supervised by William Randall, MSc (Geology), the President and CEO of Rodinia, and by Ray Spanjers, Rodinia's Manager of Exploration. Both Messrs. Randall and Spanjers are considered qualified persons, as defined by National Instrument 43-101, and both have reviewed and approved the scientific and technical information in this release. According to the Company's sampling protocol, sample size is to exceed 300 millilitres and be stored in clean, secure containers for transportation. The prepared samples are then forwarded to the ALS Laboratory Group, Environmental Division, in Fort Collins, Co (USA) for analysis. A rigorous QA/QC program is implemented consisting of regular insertion of standards and blanks to ensure laboratory integrity.

About Rodinia Lithium Inc.:

Rodinia Lithium Inc. is a Canadian mineral exploration company with a primary focus on lithium exploration and development in North and South America.

Geophysical Surveying by Malbex Expands Potential of Rojo Grande and Identifies New Drill Targets at Del Carmen Norte


TORONTO, ONTARIO--(Marketwire - Sept. 23, 2010) - Malbex Resources Inc. (TSX VENTURE:MBG) today announced that several new drill targets have been identified in geophysical surveys completed during the most recent field campaign at the Company's Del Carmen Norte gold-silver prospect in San Juan province, Argentina. The controlled source audio-frequency magnetotelluric (CSAMT) survey identified substantial volumes of elevated resistivity, which are typically associated with zones of hydrothermal silicification, the principal host of gold-silver mineralisation in high-sulphidation epithermal deposits. The survey clearly identified enhanced resistivity at the Rojo Grande target where drilling by Malbex discovered significant widths of near-surface gold-silver mineralisation in the 2009/2010 field program. A ground magnetic survey was also completed across the visibly altered area at Del Carmen Norte (Figure 1).

Highlights from the geophysical surveys at Del Carmen Norte are:

*Extensive CSAMT resistivity anomalies including

- elevated resistivity coincident with outcropping silicification and gold-silver mineralisation at Rojo Grande, where drill hole 32 intercepted 142.15 metres (m) grading 0.88 grams per tonne (g/t) of gold (Au) and 13.7 g/t silver (Ag) in vuggy silica, massive silicification and quartz-alunite alteration;
- a large resistivity anomaly, interpreted to indicate strong silicification, that is up to 1,200 metres wide and extends over 1,000 metres southwest from Rojo Grande to and beneath the steam-heated hydrothermal alteration at Cerro Amarillo; and
- discrete anomalies beneath Quebrada Pedregosa and Quebrada Del Medio that flank the central massif of alteration.

*The ground magnetic survey reveals

- an asymmetric magnetic low (2km x 3km) in the core of the altered area, which hosts the prospective Rojo Grande and Naciente Quebrada Pedregosa targets (based on longer and more significant drill intercepts in the 2009/2010 field program). This low is interpreted to reflect magnetite destruction by intense epithermal alteration; and
- the magnetic low is enveloped by semi-continuous magnetic highs (and relatively unaltered rocks), with other previously drilled targets (Cresta del Gallo, Brecha Límite, etc.) occurring along the outer margin of the magnetic low.

"We are very pleased with the results of the CSAMT survey and the number of promising drill targets that it has generated," said Dr. Peter Stewart, Vice-President Exploration. "Particularly encouraging is evidence for a substantial volume of silicification at Rojo Grande and an even larger volume of silicification (elevated resistivity) that appears to extend from Rojo Grande southwest towards and below the steam-heated zone at Cerro Amarillo (Figure 1). The potential of this latter area was highlighted recently by Dr. Richard Sillitoe following his visit to Del Carmen Norte. Given the encouraging results from our recent drilling at Rojo Grande and Naciente Quebrada Pedregosa, we look forward to drill testing these and other geophysical features when our field program resumes in October."

A separate document containing the figures referenced in this release is available at www.malbex.ca/Projects/Del_Carmen.

Geophysical surveying completed by personnel from Quantec Geoscience Argentina S.A. (Quantec) between January and April 2010 consisted of:

*127.25 line-kilometres (l-km) of ground magnetic surveying on 100 m line spacings with readings taken every 10 m, and
*14.1 l-km of CSAMT surveying on five lines separated by 400 m with measurements taken every 50 m along the surveyed lines (Figure 2).

The data processing and reporting was carried out by Quantec personnel. The Quantec report is not a "Technical Report" as defined by NI 43-101 but summarizes the survey methods, survey results and provides Quantec's interpretation of results for the geophysical surveys at Del Carmen Norte. The complete report (in Spanish), entitled "Informe de Interpretación, Estudio de Magnetometria y Audio Magnetoteluria con Fuente Controlada, Proyecto Del Carmen", is available at www.malbex.ca/Projects/Del_Carmen. Geophysical survey data collected in the 1990's by the previous operator of exploration at Del Carmen Norte was also re-processed by Quantec prior to the study reported here. Most significantly, the historic surveys included resistivity/induced polarization (IP) data for Rojo Grande and the central massif (Figure 2).

Magnetic Survey

The ground magnetic survey was aimed principally at identifying:

*areas of low and moderate magnetic signature that likely result from the destruction of magnetic minerals (principally magnetite) by hydrothermal alteration of the host andesitic volcanic rocks; and
*abrupt truncations and lineations within the gridded magnetic data that identify faults, fractures and other structures that may have localized hydrothermal flow and controlled sites of gold-silver mineralisation.

Five different images were produced from the magnetic survey data, including: total field, vertical field, inclination of the vertical derivative (second derivative), reduced to pole and analytical signal. High magnetic readings are shown in purple and red colours; low readings are shown in blue.

Three domains of magnetic character are identified in the reduced to pole image: high (Domain I), low (Domain II), and moderately to strongly reduced magnetic character (Domain III) (Figure 3). NE-SW and NNW-SSE lineaments within domains and defining domain boundaries likely represent fractures and faults. Small variations in magnetic character indicate N-S structures may also be present within the strongly altered central region (Domain II + III, as best seen in the second derivative image, Figure 4).

The Rojo Grande silicified ledge lies in low to moderately magnetic Domain III. Brecha Límite, Brecha Límite Norte and Ladera Sur de las Tortólas targets occur at the northwest boundary of this domain. The large Domain II area of low magnetic character (and most intense hydrothermal alteration) contains the Quebrada Pedregosa and Naciente Quebrada Pedregosa targets, while the clearly fracture-controlled alteration and mineralization at Cresta del Gallo is aligned with the southeast boundary between Domain II and the relatively unaltered volcanic rocks of Domain I.

CSAMT Survey

The processing of CSAMT data provides 2D resistivity sections that are colour contoured to illustrate changes in modelled resistivity (in ohm-m) for up to 500 m vertical depth. The most resistant areas are shown in white, having resistivity values about two orders of magnitude greater than the purple coloured, non-resistive (conductive) areas (Figures 5-9).

The ability of CSAMT surveys to identify hydrothermal silicification as regions of elevated resistivity is clearly demonstrated at Rojo Grande. Line 2600N shows a shallow NW-dipping strongly resistive region coincident with silicified outcrops and silicification in core from nearby drill holes (Figure 5), including hole 32. The silicified ledge at Rojo Grande is also visible as a shallow NW-dipping zone on the 2D resistivity section of line 2200N (Figure 6). The continuity of high resistivity (and silicification) between CSAMT lines is confirmed by the prior IP survey at Rojo Grande that found strong near-surface resistivity that extends northeast of line 2600N and across line 2200N to the southwest (Figure 10). The extent of the IP resistant zone is consistent with the distribution of reddish stained silicified outcrops (Figure 1).

The extensive area of low magnetic character (Domains II + III) is underlain principally by large resistive regions that appear to coalesce and widen to the southwest toward the international border and steam-heated alteration zone. These rise from 300 m deep on line 2600N to the surface by line 1800N where resistive, steam-heated siliceous alteration is underlain by a very strongly resistive region over 1 km wide (Figure 7). The presumed NE trending fault zone that separates Domain II from unaltered magnetic rocks to the southeast coincides roughly with the Quebrada Pedregosa drainage which is underlain on all surveyed lines by resistive bodies, possibly representing hydrothermal siliceous breccias in sub-vertical feeder structures. The resistivity anomalies (and localized vertical conductive panels) beneath the steam-heated zone and upper reaches of Quebrada Pedregosa on lines 1400N and 1000N are probable vertical fault zones (Figures 8,9). Smaller, sub-vertical zones of silicification exposed on surface at Cresta del Gallo, 10-30 m wide and drill tested, are not evident in the CSAMT survey data but may represent small structures extending from the larger resistive zones at depth nearby (see Figures 5,6).

Conclusions and drill targets

The magnetic survey at Del Carmen Norte defined a large magnetic low area centred on the massif of visibly altered rocks between Quebrada del Medio and Quebrada Pedregosa, most likely caused by widespread magnetite destruction and diminished magnetic signature in the altered volcanic rocks. While magnetic patterns indicate mainly NE and NW trending structures which may have influenced hydrothermal activity, more subtle magnetic features suggest N trending structures may also be present. Intersection points of fractures at different orientations are interpreted to be most prospective for enhanced hydrothermal flow, and the formation of breccias and associated higher grades of gold-silver mineralization within the large alteration system.

The CSAMT and IP surveys have demonstrated the ability to distinguish zones of silicification as resistive anomalies. The extensive resistive anomalies, both near-surface and in the subsurface, in the domains of lower magnetic and altered character, clearly constitute promising future drill targets. The main targets to be drill tested are:

*the silicified ledge at Rojo Grande – silicified outcrops, CSAMT and IP data identify a shallow-dipping NE-SW striking sheet, 800 m long by up to 400 m wide and 200 m in vertical height (A, Figure 1);
*the core of the altered massif (southwest of Rojo Grande) – the large subsurface resistive zone seen at depth on line 2200N (Figure 6) is up to 1.2 km wide on 1800N and 1400N, and apparently continues for over 1,000 metres to the southwest beneath the steam-heated zone at Cerro Amarillo (B, D and C, Figure 1); and
*multiple near-surface and subsurface resistive zones beneath the Quebrada del Medio and Quebrada Pedregosa drainages (E and F respectively, Figure 1).

The initial focus of the upcoming drill program at Del Carmen Norte will be to follow up the encouraging intersections in holes 20 and 32 (plus others) at Rojo Grande, by attempting to define horizontal and vertical continuity of mineralization and the geological and structural controls on mineralization. Malbex has initiated 3D modelling of all geological, geophysical and previous drilling using the digital elevation model derived from Jan-Feb 2010 satellite imagery. The modelling will identify those resistive sectors and fractures in the large alteration system that are most strongly mineralized, or were untested or incompletely tested in previous drill campaigns.

Dr. R. Sillitoe noted porphyry-style veining in clasts in hydrothermal breccia at Naciente Quebrada Pedregosa (PR of June 24, 2010). The very large resistive zone that underlies the steam-heated zone and other parts of altered massif southwest of Rojo Grande (anomalies B,C and D in Figure 1) is considered highly prospective for high-sulphidation mineralization similar to that at Pascua-Lama and at depth for Au-Cu porphyry mineralization similar to deposits in the Chilean Maricunga Belt (Cerro Casale, Caspiche). The premise is that elevated CSAMT resistivity reflects widespread subsurface silicification and/or quartz veinlet stockworks and breccias.

Subsurface resistivity anomalies appear to be continuous for >800 m strike length in the uppermost Quebrada del Medio and flanking most of Quebrada Pedregosa (anomalies E and F in Figure 1). Once completed, the 3D model is anticipated to provide improved drill targeting of mineralization intersected in holes 23 and 24 at the Naciente Quebrada Pedregosa target and elsewhere beneath Quebrada Pedregosa and the southern edge of the central massif of alteration.

Del Carmen Geology and Work Program

The 147 km2 Del Carmen concession package is located near the southern end of the El Indio Gold Belt, and hosts the Del Carmen Norte and Del Carmen Sur hydrothermal alteration systems. Del Carmen Norte is a large high sulphidation epithermal gold-silver system that covers approximately 9 km2. The initial interpretation of the geology at Del Carmen Norte is of a generally sub-horizontal volcanic stratigraphy where lithologies favourable for silicification and mineralisation are sandwiched between less favourable volcanic layers, and cut by steep faults that strongly influenced hydrothermal fluid flow. In addition to the geophysical surveys, 4,710 m (32 holes) of diamond drilling, mapping and rock chip sampling were completed at Del Carmen Norte in the 2009/2010 field campaign.

A second, less exposed, high sulphidation epithermal system occurs at Del Carmen Sur some 5 km to the south of Del Carmen Norte. Geological mapping, sampling and mechanical trenching were conducted at Del Carmen Sur in the 2009/2010 field season.

Newly-Listed Soltera Mining Possesses 14 KM Long Gold-Rich Quartz Vein with Characteristics of a 2M Oz. Deposit

BBXMarketWatch Journal has published a review entitled "New Issue to the Markets, World-class technical leadership with a highly prospective claim" about Soltera Mining Corp. (OTCBB: SLTA) (FRANKFURT: SN7). The review offers insight and opportunity afforded investors as Soltera focuses on the exploration of its El Torno project in the province of Jujuy, Argentina located north of Yamana's 2M+ oz deposit. The El Torno gold prospect is a past-producing gold mine and Soltera believes that modern exploration techniques will allow for the further extraction of gold from the area.

The full review may be found at: http://www.BBXMarketWatch.net/slta.htm

Excerpts:

1) "Dr. Fabio Montanari, Soltera's President/CEO, is a mining professional who literally wrote the book on mining (his text books are currently used by a number of universities in their mining graduate programs) and has personally relocated from Italy to the location of Soltera's prized El Torno mining project in Argentina to ensure success and maximize shareholder value -- certainly an example of leadership that will "walk the talk" and one of a host of reasons for us to take the time to familiarize ourselves with what may well be one for the books. The recent addition of Dr. Kevan L. Ashworth to Soltera's board of Directors should give cause for astute investors to pay attention as Dr. Ashworth is internationally renowned for his extensive knowledge and background in the mining industry and is currently a Director of a number of companies involved in mineral exploration, and is retained as an adviser by several London investment organizations."

2) "Historically, El Torno is a large gold-rich quartz vein up to 14 km long and 14 m wide that was worked by the Incas, Jesuits and Spanish and has more than 1,000 m of underground galleries. The vein extends north-south, is sub-vertical, and is accompanied in places by a stockwork system of small quartz and pyrite veins that can extend up to 300 m from the main vein. The prospect was investigated by Puma Minerals in 1997 who carried out more than 2,100 m of drilling; then by Peñoles in 1999, who undertook trenching, grab sampling, geological surveying as well as a geophysical IP survey. Soltera believes results from these two former exploration programs justify further exploration of the prospect."

3) "As the El Torno project is a past-producing mine going back centuries, the author of this article has independently investigated for the purpose of determining what type of historic results and observations serve as possible indicators and has learnt that impressive historic (non 43-101 compliant) numbers were recorded by Puma Mineral's 1997 drilling; Gold values for the main vein were between 5 g/t and 37 g/t and the stockwork system showed up to 23 g/t gold accompanied by silver in the ratio of 1:1. Subsequently Peñoles re-interpreted the Puma Minerals drill data and after further aforementioned work estimated (non 43-101 compliant) that a 1.3 km length of the vein would have the potential for more than 500,000 ounces of gold to a depth of 100 m and that a 2 to 2.5 km length to a depth of 400 m would have potential for more than 2 million ounces (assuming a grade of 10 g/t). Additionally, the current titleholder has recently (within the last year) mined parts of the upper 2 to 3 m of parts of the vein and an alluvial deposit near to the vein; the gold was recovered as particles and micro-nuggets, which suggests that gold in the vein is free rather than locked in pyrite grains."

4) "El Torno is a large proven gold-rich quartz vein up to 14 km long and 14 m wide. With under 45M shares outstanding and this new issue trading under US$1 per share the likely upside potential is clearly evident considering the following 5 points..."

Argentex drills bonanza silver intersection at Pinguino: 6.0 meters of 2,428 g/t silver on Tranquilo Trend


VANCOUVER, Sept. 13 /CNW/ - Argentex Mining Corporation's (TSX-V: ATX, OTCBB: AGXM) is pleased to release the most recent drill results from the Tranquilo vein on its wholly owned Pinguino property in Santa Cruz province, Argentina. This recent drilling, which focused on new silver-gold targets, successfully intersected the highest-grade silver mineralization ever discovered on the property.

Hole P349-10, which was drilled into the 11-kilometer long Tranquilo Trend crosscutting the Pinguino property, returned a thick intersection of high-grade silver mineralization containing 6.0 meters of 2,428 g/t silver, 0.22 g/t gold, 0.32% copper and 0.74% lead. This new mineralization was discovered at shallow depths of less than 15 meters within the oxidized zone. Holes P349-10, P348-10, P358-10 and previously published hole P323-10 together confirm a new mineralized trend containing bonanza-grade silver. This trend is in excess of 275 meters in length and remains open ended along strike and at depth.

"These are truly spectacular silver results from Tranquilo. This prominent regional Tranquilo fault remained the largest untested structure at Pinguino until commencement of our 2010 drill program," said Ken Hicks, President of Argentex. "The discovery of this type of bonanza-grade silver mineralization within such a massive structure has added a new dimension to Pinguino's potential. Tranquilo has emerged as the most significant silver discovery at Pinguino to date and we intend to focus our exploration efforts there on further expansion and definition."

Results

The following table displays selected analytical results from the Tranquilo and Luna veins, both located within the northwest Tranquilo Trend. All of the holes in the table intersected oxidized gold and silver mineralization. A map of drill hole collars is available on our web site.



A total of 89 drill holes (P270-10 through P358-10) covering 6,224 meters have been completed at the Pinguino property as part of the 2009-10 drill program. The program was designed to drill test new precious metal targets and expand known discoveries. Drilling focused on precious metal discoveries in the Tranquilo and Luna veins, two major new silver and gold veins located within the 11-kilometer long Tranquilo Trend.

About Pinguino

Pinguino is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province. With more than 75 line kilometers of veins discovered to date, the Pinguino property is host to the largest known undeveloped vein system in Santa Cruz province after the developed AngloGold Ashanti Cerro Vanguardia mine. Both vein systems fall within the Tranquilo Trend, a major northwest structural corridor in central Santa Cruz.

Quality Assurance

Exploration samples selected for analysis are sent to Acme Analytical Laboratories' sample preparation lab in Mendoza, Argentina. From there sample pulps are sent to Santiago, Chile for fire assay gold analysis and to Vancouver, Canada for Group 1DX multi-element MS-ICP analysis. Samples with over-limit zinc, lead, silver and/or copper are reanalyzed using an ore-grade high detection limit 7AR analysis, also conducted in Vancouver.

Mirasol Discovers Multiple New Silver Veins at the Virginia Vein Zone, Argentina


VANCOUVER, Sept. 15 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ, Frankfurt: M8R) is pleased to report results from the 100%-owned Virginia Vein Zone in southern Argentina. Exploration has previously focused on the Julia Vein as well as the nearby Ely, Margarita and Naty veins, which host high-grade silver values over significant widths and strike lengths (see press releases of Feb. 16, 2010 and June 07, 2010). Current exploration highlights the discovery of additional silver-bearing veins, the Roxane, Martina, Priscila and Magi veins. Assay results show significant silver grades in all new veins including assays up to 2,880 g/t silver from the Roxane Vein.

The four new veins host important silver mineralization and substantially increase the cumulative strike length and footprint of veins at the Virginia Vein Zone, which now exceeds 9,600 metres (Figure 1).

Mapping and sampling of the Virginia Vein Zone is now complete for the 2009-2010 field season. Drill targets are being identified and prioritized based on the geology, assay results and geophysics completed. Environmental permitting for drilling is well advanced. It is the intention of Mirasol management to undertake the first round of drilling at the Virginia project during the southern hemisphere summer.

Technical Discussion
--------------------

Assays reported here include channel and rock chip sampling from the Roxane, Martina, Priscila and Magi veins. Saw-cut channels were selected by Mirasol geologists to give a systematic test along strike where distribution of outcrop permits.

Twenty-four rock chip samples of the Roxane Vein (Figure 2) returned assays which range from 103 to 2,880 g/t silver with an average of 1,039 g/t silver (Table 1). The Roxane Vein is adjacent to and parallels the central segment of the high-grade Julia Vein that also hosts multiple channel samples with values exceeding 1,000 g/t silver.

The Roxane Vein, as known to date, is defined by a northwesterly trending zone of aligned float blocks up to 0.7 metres wide that can be traced for a strike length of 590 metres (Figure 2). The true width of the vein is unknown; trenching and/or drilling will be required to determine the vein's grades and widths. Veins material is composed of fine-grained, massive to banded saccharoidal quartz with abundant iron oxides including specular hematite and occasionally minor galena.

composites range from (less than)0.05 g/t to a maximum of 0.46 g/t
and hence are not tabulated.

The Priscila Vein is northeast trending and has been traced in outcrop and subcrop over a strike length of 410 metres (Figure 2). Sampling comprises both saw-cut channels and rock chips. The Priscila vein is up to one metre in width, composed of chalcedonic to fine grained saccharoidal quartz containing abundant iron oxides. Assays to date have returned silver up to 104 g/t.

7. Channels so marked have sampling gaps greater than 20% of their total
length. See Technical Appendix of March 4, 2010 press release.
8. Gold assayed by Au-AA24, a fire assay collection method with atomic

composites range are all (less than)0.05 ppm.

The Martina Vein is located north of the Priscila Vein, is 400 metres long with a sinuous strike ranging from northeasterly to northwesterly. To the northwest the vein is covered by a soil-filled valley (Figure 2). Subcropping and outcropping veins on the north side of the valley may be the continuation of the Martina Vein. Grades of the channel sample composites increase towards the northwest nearing the soil-filled valley. Table 3 shows the average grade of 19 channel composites from the Martina Vein is 110 g/t silver, however the northernmost 6 channel composites have an average grade of 248 g/t silver. In the higher grade segment, channel samples were mainly collected from subcropping blocks with widths of 0.11 to 0.89 metres. The true width of the vein is uncertain. Typically the vein is comprised of chalcedonic to fine grained saccharoidal quartz with abundant iron oxides.

composites are all (less than)0.05 g/t.

Magi Vein is the easternmost vein discovered to date at Virginia (Fig. 2). The vein has a northwesterly trend, is intermittently exposed over a 770 metre strike and reaches 3 metres in width. Quartz textures in the vein are generally fine-grained and chalcedonic, and contain less iron oxide than the veins further west. Silver assays from the vein range from 1 to 39 g/t silver with lower concentrations of lead and arsenic than typically seen elsewhere in the Virginia Vein Zone. Two blocks of float with high silver assays to 2,970 g/t to the east are texturally different from the outcropping vein and may source from an as yet unidentified vein source.

District scale zoning patterns are evident at the Virginia Vein Zone. Silver, base metals and trace element results generally are lower towards the east. These trends, together with the quartz textures are tentatively interpreted to indicate progressively lower temperature levels in the mineralized system towards the east, and are interpreted to indicate that the Martina, Priscila and Magi veins are exposed at progressively shallower levels, or peripherally, in the hydrothermal system. This suggests that the eastern veins have potential to increase in silver grade at depth.

The Agreement was signed on September 21, 2010, following the Letter of Intent announced in the Company's news release of April 13, 2010.

Under the terms of the Agreement, Calypso has granted Cameco Global the option to acquire a 51% interest in Energia Mineral by Cameco Global investing a total of C$9,000,000 in Energia Mineral's Argentine uranium properties, over a maximum three-year period. During the first year of the Agreement, Cameco Global has committed to fund C$3,000,000 of Energia Mineral's agreed exploration and development programs. The decision to proceed with a further $3,000,000 in exploration in years two and three is at Cameco Global's discretion.

The Energia Mineral project areas included in the Agreement cover approximately 442,542 hectares and include the La Pintada, Ranquil Co, Central Block, Campesino Norte and San Jorge Basin projects.

"We are excited to have Cameco, a recognized uranium industry leader as our partner in our exploration activities in Argentina. Their extensive experience in all aspects of exploration, development and production will significantly strengthen the development of our projects over the medium and long term," said Stephen Barley, President of Calypso.

Under the terms of the Agreement, Energia Mineral will continue to lead exploration activities during the option period based on exploration proposals approved by a joint technical committee. In the event Cameco Global exercises its option and acquires a 51% interest in Energia Mineral, Cameco Global has the right but not the obligation to become the operator.

Guillermo Pensado, Vice President Exploration of Calypso and President of Energia Mineral, said, "The signing of this agreement is a testament to the quality of the properties the Company has assembled in areas of Argentina with high uranium potential, and we look forward to working with Cameco through the joint technical committee to deliver the agreed exploration program."

Artha Resources Corporation: Argentina Rare Earth Update


VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 20, 2010) - Artha Resources Corporation (TSX VENTURE:AHC) is pleased to announce that the company continues to make significant progress on its 100% owned Cachi Rare Earth property in Salta Province, NW Argentina (Map 1: http://media3.marketwire.com/docs/Artha920.pdf).

* Reconnaissance work has been completed on 30,000 hectares, in the southern half of the 60,000 hectare property.
* A total of 129 stream sediment samples and 182 rock chip samples were collected and the area was mapped at a scale of 1:25 000.
* Three targets have been recommended for follow-up based on recent results, focusing on niobium-tantalum type mineralization with accessory REE.

The work programs recently completed by Artha are the first modern and systematic mineral exploration ever done in the area and as such Artha considers the prospectivity of the property to be very high based on the geology and results to date.

The stream sediment sampling has reported geochemical anomalies of tantalum, niobium, cesium, uranium, thorium, hafnium plus some REE anomalies to the south of the property and zinc and lead to the north of the property. Based on the spatial distribution of the anomalies we have identified three exploration targets (Map 2: http://media3.marketwire.com/docs/Artha920.pdf):

* Target 1: Located in the southernmost part of the property, with anomalous values of niobium (30-40ppm Nb), uranium (up to 13ppm U), thorium (20-25ppm Th), tantalum (3-5ppm Ta), hafnium (10-14ppm Hf) and total rare earths elements (207-432ppm TREE)
* Target 2 : Located in the Northern part of the sampled area, with anomalous values of tantalum (3-11ppm Ta), niobium (up to 40ppm Nb), Zn (100-300ppm Zn), Lead (111-146ppm Pb), cesium (100-1000ppm Cs), rubidium (up to 212ppm Rb) and total rare earths elements (200-336ppm TREE).
* Target 3: Located in the northernmost part of the sampled area, with anomalous values of zinc (100-171ppm Zn), cesium (120-1215ppm Cs), lead (up to 184ppm Pb), hafnium (up to 10ppm Hf) and total rare earth elements (200-220ppm TREE).

Follow-up work is being planned and will begin in Q4.

The Cachi property covers over 550 square kilometres in Salta Province NW Argentina was staked based on large pegmatite intrusions extending for 40km in strike length. The metallogeny includes pegmatite-hosted niobium-tantalum mineralization in the Precambrian metamorphic basement; some polymetallic veins associated with Tertiary volcanics and Quaternary evaporite deposits.

Geology is prospective for pegmatite related rare earth mineralization based on extensive granitoid intrusions, extending for over 40km in strike, with large (up to 300m wide) Pegmatite dykes intruding neo-proterozoic gneiss. Many pegmatites have been economically valuable as sources of clays and feldspars, as well as bismuth, lithium, molybdenum, rare-earths, tantalum-niobium, thorium, tin, tungsten, and uranium minerals.

The Susques properties, cover more than 415 square kilometres in southern Jujuy Province, NW Argentina (Map 1). Susques is known to be prospective for a variety of rare earths elements, including yttrium, and thorium has been historically mined on a small scale. The local geology is dominated by Ordovician sediments and Tertiary intrusives and Carbonatites with little detailed exploration ever done. Rare earth mineralization observed to date is hosted in stockwork veins with the host structures up to 10 meters wide and over 6km in strike length.

Work programs are planned to restart, after the winter break, in late October. Programs will target detailed surface sampling and mineralogical studies to determine the concentrations, spatial distribution and continuity of the mineralization encountered to date. The combination of heavy rare earth elements with silver, copper and lead and zinc, coupled with a major paved highway to Chile passing through the property make it a very exciting target.

Charles Straw, B.Sc., is the qualified person under NI 43-101 responsible for the technical information in this news release.

Artha was founded by a team of mining industry professionals with a proven track record in project generation, exploration, mining and finance. The Company's principle exploration target adjoins Silver Standards Pirquitas Mine, one of the largest primary silver mines in the world located in the province of Jujuy in NW Argentina. Artha is one of the largest mineral explorers in this region with over 1500 square kilometers of properties prospective for silver, gold, base metals and rare earths.
