Mariana Reports High-Grade Gold Intersected at La Morena Vein-Breccia Zone and Extensions to La Calandria Vein-Breccia, Las Calandrias


VANCOUVER, BRITISH COLUMBIA, Jul 26, 2011 (MARKETWIRE via COMTEX) -- Mariana Resources Ltd. /quotes/zigman/5425717 CA:MRY -7.14% (asx:MARL)(plus:MARL) ('Mariana' or 'the Company'), the AIM and TSX quoted exploration and development company focused in Argentina and Chile, is pleased to report on drilling results from the final 17 holes from the Q1/Q2 2011 drilling programme at the Calandria Norte target area at its 100% owned Las Calandrias Gold-Silver Project ('Las Calandrias'), in southern Argentina.

Highlights


























Commenting today, Chairman John Horsburgh said, "Having announced positive results from Calandria Sur drilling last week, we are very encouraged that the gold intersections along the La Morena and Tongoril trends highlight the potential of the Calandria Norte Dome to host multiple vein-breccias. La Morena vein-breccia, the dome root zone where the high grade vein-breccia systems could converge, lateral extensions to La Calandria vein-breccia mineralisation and the untested 550m La Calandria strike extension are compelling targets for the next drill campaign, due to commence in August 2011."

Drilling Programme

Seventy-three diamond holes have been drilled to date at Calandria Norte for 10,586m. The programme last quarter consisted of 17 holes totaling 2,669m. Of these, 12 were drilled at La Calandria vein-breccia, two at La Morena, two at Tongoril and one at other targets. Refer to drill plan (Figure 1) for hole locations, longitudinal section (Figure 2), cross sections (Figures 3-5) and summary of significant intersections in the table below.

The recent resource study has included La Calandria vein-breccia but these drill results were received too late for inclusion in the resource model. The results will be integrated in a subsequent resource update.

La Morena Vein-breccia

One of two holes drilled at the La Morena target in the northern part of Calandria Norte rhyolite dome, 250m NW of La Calandria vein-breccia, intersected high grade mineralisation - 0.6m @ 68.1 g/t Au and 107g/t Ag (69.9 g/t AuEq) from 59m in CND250. La Morena is a branching NNE striking vein-breccia system, dipping steeply SE with a wide hangingwall stockwork.

Seven previous shallow holes intersected concealed chalcedonic silica and sulphide vein-breccia along a 350m trend with a best intersection of 0.8m @ 12.0 g/t Au and 32 g/t Ag from 90m (in CND146). Narrow high-grade silver mineralisation was intersected in CND152, 180m ENE of CND146, with 1m @ 981 g/t Ag from 140 m. The vein-breccia system has no surface expression and was discovered by drilling the SW end of chargeability Induced Polarisation anomaly.


La Calandria Vein-breccia

Results were received for 12 holes drilled as infill or for possible extensions to the vein-breccia system. CND247 which intersected 0.53m @ 23.7 g/t Au and 21 g/t Ag from 221.9m is one of the deepest intersections along the zone 200m below surface which is open at depth and along strike. Hole CND247 is outside the resource outline. The other holes are mostly within the outline and support the initial resource estimation (see below).

In the central-east sector, shallow scissor hole CND240 intersected a wide zone of stockwork veinlets and quartz breccias assaying 21.5m @ 1.0 g/t Au & 6 g/t Ag from 31m in the footwall of the vein-breccia.

In the western lateral zone, two additional holes (CND226-CND227) west of bonanza intersection CND132 - 0.8m @ 90.2 g/t Au and 198 g/t Ag from 132.1m, 120m below surface, did not intersect the vein structure.

The updated gm-m Au longitudinal section (Figure 2) shows +10gm-m Au mineralisation commencing at 30m below surface at its centre and 100m below surface on the flanks. The vein system (up to 1.5m wide) dips steeply NW strikes for 500m and has a vertical extent of 125m, increasing to 200m or more on the northeastern flank. The zone remains open at depth on the ENE and WSW flanks.

Tongoril Vein-breccia

The Tongoril vein-breccia trends NE-SW for approximately 200m close to the dome margin about 75m SE of La Calandria. An intersection in CND241 of 6m @ 1.6 g/t Au, including 1m @ 5.4 g/t Au) opens up another vein-breccia target.

Calandria Norte Exploration Follow Up

Further drilling at La Morena will target extensions and the possible intersection with the La Calandria Vein-breccia at depth.

Mapping, trenching, rock and LAG sampling underway SW of the Calandria Norte Dome has discovered the El Clavo vein trend interpreted as a SW extension of the La Calandria Vein-breccia into the surrounding volcaniclastics. Zones of intense pervasive and vein-style silicification outcrop irregularly over a 550m strike with rock chips assaying between 0.2 and 1.4 g/t Au from initial sampling.

Drilling will resume in Las Calandrias by Mid-August with a minimum of 5,000m planned in the principal target areas.

La Calandria Initial Resource
The initial resource estimate for La Calandria, which includes both high-grade vein-breccia and low-grade stockwork mineralisation, is 886,000t Indicated @ 2.26 gAuEq/t (2.16 g/t Au, 5.6 g/t Ag) - contained gold 61,000 ozs, silver 159,000 ozs. The Inferred resource is 366,000t @ 1.17 gAuEq/t (1.17 g/t Au 3.3 g/t Ag) with contained 13,100 oz gold and 39,000 oz silver.

LeachWell(R) tests on intercepts from six drill holes have indicated high average recoveries of 89.5% for the oxide zone, 94.5% for the transition zone and 86.0% for the primary zone. Consequently, economic treatment of all the mineralisation at La Calandria by heap leaching or carbon-in-leach (CIL) may be feasible, subject to further LeachWell(R) tests on the remaining drill holes and testwork.





















Las Calandrias Project Background

Las Calandrias comprises multiple zones of gold mineralisation hosted by rhyolite domes over a 10.5 sq km area. In 2009, phase I drilling (September-October) consisted of 16 scout holes (1,566m) testing the Calandria Norte vein-breccia and Calandria Sur dome breccia targets where significant gold mineralisation was discovered. The phase II drilling (March-April 2010) consisted of 4,400m in 37 holes and tested Calandria Sur (28 holes/3,212m); Calandria Norte (2 holes/299m), El Nido Este (2 holes/309m) and El Nido Norte (5 holes/580m). The phase III drilling (September-December 2010) consisted of 14,003m in 110 holes; Calandria Sur (56 holes/6,186m); Calandria Norte (43 holes/6,175m); Nido Norte (7 holes/1,054m); Nido Oeste (2 holes/421m); La Herradura (2 holes/168m). The continuity of phase III (January-April 2011) consisted of 15,736 m in 90 holes; Calandria Sur (6 holes/2,747m); Calandria Norte (21 holes/3,430); Despreciada: Nido Norte and Nido Centro (37 holes/6,414m); Nido Oeste (7 holes/1,130m); Nido Sur (18 holes/1,883 m); Gamekeeper (1 hole/132 m).

The Q1 2011 drilling was undertaken by ECOMINERA.

Regulus Commences 15,000 Metre Drill Program on Rio Grande


WATERDOWN, ONTARIO--(Marketwire - July 25, 2011) - Regulus Resources Inc. (TSX VENTURE:REG) ("Regulus), is pleased to announce that drilling is now underway on the company's 50%-owned Rio Grande copper-gold-silver project in Salta Province, Argentina after an unusually intense winter storm in the Puna during the mobilization caused some delays. The drill program is planned for a total of 15,000 m utilizing two diamond drills. The Rio Grande project is a 50/50 joint venture between Regulus and Pachamama Resources Inc. ("Pachamama", PMA TSX.V) with Regulus acting as the operator.

Over the last two months, the company has made significant progress in preparing the Rio Grande project for its first drill program since 2008 as well as making advancements towards obtaining its first 43-101 compliant resource estimate on the project. The following programs are now completed or are underway;

* Quantec Titan 24 geophysical IP and resistivity survey
o Completed 11 lines – Phase I report evaluation pending – 3D modelling underway
* RDI and SGS metallurgical test work
o Expecting final results from both labs in August
* Wardrop Engineering 43-101 compliant resource estimate
o Well on its way for completion in August (based on previous drilling only)
* 15,000 metre Boart Longyear diamond drilling program
o Both drills are now on site with the first drill operating

The 15,000 metre diamond drilling program will consist of 1) infill and extension drilling in the northern area of the Sofia Zone, 2) extension drilling to the west of the existing drilling in the North Zone, 3) infill and extension drilling in the # 7 Zone, 4) initial testing of the underexplored southwest portion of the Rio Grande ring structure, 5) deep drilling into the deep porphyry targets in the center of the Rio Grande ring structure.

Wayne Hewgill, President and CEO of Regulus comments: "We are very excited to be back drilling and testing the outstanding potential at the Rio Grande project after a 2 ½ year break. During the financial crises of 2009, Antares Minerals Inc. put the project on hold to focus its exploration funding on their world-class Haquira copper-molybdenum porphyry discovery in southern Peru, which led to the sale of Antares to First Quantum Minerals Ltd. in December 2010 and the spin-out of Antares' 50% interest in the Rio Grande project into Regulus. While earlier results from the 78 diamond drill holes on the project returned excellent results, including 189 metres grading 0.70% Cu and 0.67 g/t Au and 11 g/t Ag, we are only now anticipating completion of the first 43-101 compliant resource estimate on the property. We expect the results of the preliminary metallurgical work and the first resource estimate to be released in Q3."

To more clearly define the deep porphyry targets in the centre of the 2.2 km wide Rio Grande Ring structure, the company contracted Quantec Geoscience to complete a 10 line, Titan 24 IP / resistivity survey covering the full extent of the Rio Grande ring structure. The IP successfully outlined the contact between the oxide and transitional material and the underlying fresh volcanic rocks and the MT survey outlined a number of high priority drill targets at depth in the central area of the Rio Grande Ring structure. An additional line was added to the survey covering the Northeast Gold target located 1.6 kilometres from the eastern edge of the Rio Grande ring structure.

Mariana Resources appoints new director to support Canadian exposure


South America-focused gold miner Mariana Resources (LON:MARL, TSX:MRY) has appointed J. Christopher Mitchell as a new non-executive director to its board.

The move is designed to complement the company’s strategy of bolstering its exposure in Canada after the firm’s recent listing on the Toronto Stock Exchange.

Mitchell is a Vancouver-based financial adviser to listed companies active in the mineral exploration and production arena. During his 40-year career, he has served in senior executive positions with several listed mining companies and he currently serves as chief financial officer of several TSX Venture Exchange-listed companies and as a non-executive director of three junior mineral exploration companies.

These companies include Endurance Gold Corporation, First Point Minerals Corporation and Skyline Gold Corporation.

"His specific industry and Canadian experience will be invaluable to Mariana following our listing on TSX and as we look towards expansion of our Las Calandrias gold-silver resources in Argentina,” said Mariana’s chairman, John Horsburgh.

Mariana’s shares began trading on the TSX in mid-June. The decision to list there was taken in order to “give the company wider access to the increased institutional and retail shareholder following in the North American markets”, said Horsburgh at the time.

Mariana is focused on gold and copper-gold prospects in Chile, Argentina and elsewhere in South America. The firm’s strategy is to seek underexplored areas with potential for high-grade polymetallic gold mineralisation.



NovaGold Reports Drill Results at San Roque Project in Argentina

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 21, 2011) - NovaGold Resources Inc. (TSX: NG)(NYSE Amex:NG) today announced the results of its initial drill program at the San Roque project in the Rio Negro Province of Argentina.

The program was designed to test three areas at the San Roque project; the Del Indio zone (now called the Zone 33 Area), a series of IP and resistivity anomalies, and the Zone 51 Area. The locations of the drill holes are shown on the location map below.

Significant intercepts are shown in the table below






A second drilling campaign is now being planned. This program will include a 15-line-kilometer IP/Resistivity survey and a 3,500-5,000-meter HQ-size drill program. The drill program is planned for completion before the end of 2011.

Joe Piekenbrock, VP Exploration commented, "This early success at San Roque is encouraging, particularly the significant widths of mineralization encountered. Our goal with the second round of drilling is to expand on the potential resource in Zone 33 Area and capitalize on the extensive exploration potential that we recognized in the initial round of drilling."

NovaGold signed an option agreement with Marifil Mines Ltd. ("Marifil") on June 22, 2010, which gives NovaGold the right to earn up to a 70% interest in the San Roque Project. The San Roque project comprises eleven claims totaling 70,046 hectares. Three of the claims are owned by MIM Exploraciones SA ("MIM") and Marifil has exercised its right to purchase a 100%-interest in these claims for $400,000.

The drill program and sampling protocol were managed by NovaGold. The HQ diameter diamond drill holes were sampled using a two-meter sample length and recovery averaged 95%. Three quality control samples (one blank, one standard and one duplicate) were inserted into each batch of 20 samples. The drill core was sawn, with half sent to ASL Chemex Labs in Mendoza, Argentina and Santiago, Chile, where gold was analyzed by fire assay and AAS finish and a four acid ICP-MS method was used to analyze a full suite of elements. Samples were securely transported from the project site to the ALS Chemex laboratory in Mendoza via a private truck hired by ALS.

Heather Brown, P.Geo, GIS Database Geologist for NovaGold, and a Qualified Person as defined by National Instrument 43-101, has reviewed the results of the drill program and confirmed that all procedures, protocols and methodologies used in the drill program conform to industry standards.

Minera Andes Announces Second Quarter 2011 San Jose Mine Production


TORONTO, ONTARIO--(Marketwire - July 20, 2011) - Minera Andes Inc. (the "Company" or "Minera Andes") (TSX:MAI)(OTCBB:MNEAF) announces production results from its 49% owned San José mine in Santa Cruz Province, Argentina. Overall production at the San José mine during the second quarter of 2011 was 1,332,000 ounces of silver and 17,700 ounces of gold, of which 49% is attributable to Minera Andes. Production cost information will be provided in conjunction with our second quarter 2011 financial results expected to be released mid-August.

Compared to the first quarter of 2011, second quarter 2011 silver production was 12% lower and gold production was 17% lower. The decrease in silver and gold production was due to a 14% reduction in mill throughput because of a strike at the mine during the second quarter of 2010, which resulted in the loss of 18 days of production. The principal issue surrounding the strike was wages, and a final agreement has been reached with the local union. In addition, annual wage negotiations with the union have reached a satisfactory conclusion. The wage agreements were in line with expectations.

Compared to the second quarter of 2010, second quarter 2011 mill throughput decreased 15% due to the strike at the mine during the second quarter of 2011. However, the silver head grade and metallurgical recovery increased in the second quarter of 2011 compared to the second quarter of 2010, resulting in a net increase of 9% for silver production. The gold head grade was essentially unchanged, but higher metallurgical recovery for gold partially offset the lower mill throughput, resulting in a net decrease of 10% for gold production compared to the second quarter of 2010. Metallurgical recoveries improved to 89% for gold and 87% for silver in the second quarter of 2011 compared to 85% for gold and 81% for silver in the second quarter of 2010.

The difference in the amount of metal sold in the quarter compared to the amount produced was due to timing differences.

Troy Resources NL: Kamila Southeast Target Drilling Continues to Deliver High Grade Results


PERTH, WESTERN AUSTRALIA--(Marketwire - July 19, 2011) - Troy Resources NL (TSX:TRY)(ASX:TRY) -

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES


* Drilling along strike and southeast of Kamila Reserve extends new, high-grade gold-silver mineralised zone.
o Hole CA-11-316 reported an interval of 3.45m at 21.59g/t gold and 1240.35g/t silver or 39.30g/t Au_eq from 315.35m, downhole;
o Hole CA-11-317 reported an interval of 2.0m at 10.99g/t gold and 312.50g/t silver or 15.45g/t Au_eq from 323.50m downhole.
* Mineralised zone remains open along strike, as well as up and down dip.
* Second Rig added to program in late June to complete Infill drilling targeting Resource estimate in September quarter.

Troy Resources NL ("Troy") is pleased to announce further assay results from recently completed drilling at the Company's flagship Casposo gold and silver mine in San Juan, Argentina, which continue to extend the new high grade gold-silver mineralised zone along strike and to the southeast of the existing Kamila Reserve.

The new holes include a series of step-outs and infill holes from earlier reported gold–silver intercepts on the Inca Vein within the Kamila Southeast Extension Target, most of which intercepted the modelled Inca Vein surface as planned.

The new intercepts have added significantly to the understanding of the Kamila Southeast Target and continue to confirm the high grade gold and silver values associated with the Inca Vein within the zone (see Figure 1, Figure 2 and Table 1). Intercepts include:

* CA-11-314: 0.5m at 4.70g/t gold and 104.0g/t silver or 6.19g/t Au_eq from 338.8m and 1.15m at 3.95g/t gold and 14.83g/t silver or 4.16g/t Au_eq from 350.25m downhole;
* CA-11-315: overshot the modelled pierce point Inca Vein target and this resulted in no significant assays;
* CA-11-316: 3.45m at 21.59g/t gold and 1240.35g/t silver or 39.30g/t Au_eq from 315.35m, including 0.90m at 59.19g/t gold and 3751g/t silver or 112.78g/t Au_eq from 315.35m downhole;
* CA-11-317: 2m at 10.99g/t gold and 312.50g/t silver or 15.45g/t Au_eq from 323.50m downhole.

Drilling to date has focussed on the 430m zone adjacent to the post mineral dyke. The zone remains open along strike for one kilometre, as well as up and down dip.

Chief Executive Officer, Paul Benson said: "Our current objective is to complete the drilling required for a Resource Estimate on this new zone in the September quarter and if the infill drilling is positive, a Mining Reserve by the end of the calendar year."

"Our focus in the coming months will be to determine if we can prove up sufficient high grade material to justify commencing underground development earlier than currently planned."

Mr Benson said the man-portable drill has been repositioned and has commenced drilling on the one kilometre long outcropping Lucia Vein located 3 kilometres north of the plant. This rig will sequentially test the highest ranked drill targets from the numerous outcropping veins to the northeast of the Kamila structural corridor as well as the Castaño Nuevo and Don David Joint Ventures 23 kilometres to the north.

"In addition to a substantial drilling effort, a contract has been awarded for detailed helicopter magnetics and a radiometric survey over the Casposo Property and the JV areas. Follow-up ground magnetics and Induced Polarization surveys will also be undertaken to assist in delineating covered drill targets."

*Approximately 82% of the total contained gold and 97% of the contained silver are from Calandria Sur.

*Drill spacing is deemed to be sufficient for 93% of the resource, in terms of resource tonnage, to be assigned to the Indicated category.

*The reporting cut-off grades are 0.3 g/t AuEq for oxide and transition and 0.7 g/t AuEq for the primary sulphide zone. Gold equivalent (AuEq) is calculated using the long-term silver to gold ratio of 60:1 and was used for reporting cut-off only.

* Potential exists to extend known zones of mineralisation in the next drill campaign.

Estimation Process

The process of estimation began with sectional interpretations at multiple orientations spaced on 25m centres. Solids, surfaces and polygons were modelled for the rhyolite dome, tops of geologically logged primary and transitional oxide zones, and gold and silver domains, respectively. Samples were coded from sections, statistics were completed on both the gold and the silver assays, and sample grades were capped.

Geostatistics were performed and the resource was estimated utilizing the inverse-distance cubed algorithm.

Because of varying metallurgical recoveries and consequent recovery processes, the resource is reported at two cut-off grades. MDA believes that the resource reporting cut-off would best represent material with "reasonable prospects for economic extraction" at 0.3g AuEq/t for oxide and transition material and 0.7g AuEq/t for primary (unoxidized) material. Exploitation at Las Calandrias will most likely be by open-pit mining methods and costs from comparative operations were used to determine the reporting cut-off. Metallurgical extraction, presumed metallurgical processes, and costs were determined (see News Release dated 6th July 2011) by Peter Lewis of Peter J. Lewis & Associates Pty. Ltd., Sydney, Australia. Mr. Lewis is an independent Consulting Metallurgist. Gold equivalent is calculated using the long-term silver to gold ratio of 60:1 and was used for reporting cut-off only.

Resource Dimensions

To date, the Calandria Sur deposit's resource has been defined at 700m long (limited by the southern property boundary) by 250m wide by 120m thick. The overall shape is roughly elongate oval but cut in half horizontally at the topographic surface. The long dimension strikes at about N50°W. The La Calandria deposit is just less than 500m long by 80m wide by 200m thick. The overall shape is tabular, with a strike of about N50°E and dip at around 70°to the northwest.

Mineral Domains

Three gold mineral domains were modeled for each deposit. The two lowest-grade domains are best described as having weak (low-grade domain) to moderate (mid-grade domain) stockwork mineralization. Likely there is a component of disseminated mineralization in these two. The highest-grade domain is a mix of styles of mineralization, but almost always has some sort of mineralized vein and/or vein breccias, intense stockwork or strong, but local impregnations of black sulfides. The high-grade domain appears to have definable continuity on a few sections. Many of the high-grade mineralized structures (>~ 4g Au/t) lie within a zone that parallels the country rock/dome contact at Calandria Sur.

La Calandria Undiluted

In the event that La Calandria is found to be economic by underground mining, an undiluted resource was presented to portray what might be a reasonable expectation of grades and tonnages. At a cutoff of 3.0g AuEq/t and within the reported resource, there are 162,000 Indicated tonnes grading 9.17g Au/t and 11.00g Ag/t for a total of 48,000oz of Au and 57,000oz of Ag.

Preliminary Metallurgical Testwork (See news release 6th July 2011)

Preliminary testwork has outlined a number of potentially economic processing options, for both the Calandria Sur and La Calandria gold-silver deposits, subject to further testwork. Highlights of the release as follows:

Calandria Sur

*A column heap leach test on the oxide zone composite gave recoveries of 79.5% for gold and 54.5% for silver

*A carbon-in-leach (CIL) test on the oxide zone composite gave recoveries of 94.6% for gold and 89.6% for silver.

*Selective flotation on the primary zone composite produced a high value concentrate assaying 40.7g/t Au, 884g/t Ag and 40.2% S at gold and silver recoveries of 82.1% and 82.9%, respectively.

*On the primary zone composite recoveries of 83.3% for gold and 75.2% for silver were obtained by bulk sulphide flotation followed by pressure oxidation and then cyanidation of the flotation concentrate.

*Alternative processing options to be investigated in future testwork include:

*Heap leaching and CIL processing of the combined oxide and upper transition zones, with heap leaching currently favoured because of its lower capital and operating costs.

* Bulk sulphide flotation followed by oxidation and cyanidation of the concentrate and selective flotation of a saleable concentrate on the combined primary and lower transition zones, with selective flotation currently favoured because of its lower capital and operating costs.

La Calandria Vein

*LeachWell® tests on intercepts from 6 drill holes have indicated high average recoveries of 89.5% for the oxide zone, 94.5% for the transition zone and 86.0% for the primary zone.

* Consequently, economic treatment of all the mineralization at La Calandria by heap leaching or CIL may be feasible, subject to further LeachWell® tests on the remaining drill holes and testwork.

Exploration Potential

A detailed study of exploration potential of Las Calandrias by Mariana is close to completion. This includes evaluation of the last results of the third drill campaign which have now been received and will be released shortly once interpretation is completed. (The drill results were received too late to be included in the initial resource modelling). In addition, on-going exploration during the winter season has included mapping, soil sampling and trenching, mostly in volcanoclastic rock terrain that surrounds the rhyolite domes. It is anticipated that a number of new targets will be generated from this work, which in addition to possible extensions to both Calandria Sur and La Calandria, will point to further resource upside at Las Calandrias.
