Atna Resources Ltd.

Atna Announces Gold Participating Bond Offering

       GOLDEN, CO, July 5, 2010 - Atna Resources Ltd. ("Atna" or the "Company") - (TSX: ATN, OTC BB: ATNAF) is pleased to announce that it has engaged Canaccord Genuity Limited and CAT Brokerage AG to arrange a private placement offering (the "Offering") of tranche B of gold participating bonds (the "Bonds"). Canaccord Genuity Limited will also act as placing agent in connection with the Offering of the Bonds.
       The Bonds, which will mature on September 30, 2014, and will bear interest at a rate of 8.5 percent per annum on the declining balance. The Bonds will represent a senior unsecured obligation of Atna by way of a corporate guarantee. The Bonds will be redeemed in 16 equal quarterly installments based on a Gold Equivalent Amount. The Gold Equivalent Amount will be established, at closing, by dividing the amount of the Offering by the lesser of the London PM fixing price and the trailing 30 calendar day average gold price based on the London PM fixing price. The quarterly gold deliveries will be converted to participating interests in a gold exchange-traded fund equivalent to the value of gold ounces delivered.
       It is anticipated that the amount of gold committed over the term of the Bonds, including the previous tranche A bonds will represent less than 20 per cent of the average annual forecast gold production of Atna's wholly-owned Briggs Mine in California over the term of the Bond. Atna intends to use the proceeds of the Offering for general corporate purposes including the construction and development of its Reward Gold Mine in Nevada. Closing of the Offering will be subject to final documentation as well as regulatory and final board approvals.
       "We have now made two payments on our tranche A gold participating bonds and the structure, which is non-dilutive to our shareholders, is working as expected. Closing this second tranche of gold participating bonds will further strengthen our balance sheet and allow us to initiate drilling operations at our Briggs and Reward gold properties and to further advance construction activities at our Reward Gold Project. Reward is expected to commence facility construction during Q3 2010 and enter production in the summer of 2011. This will afford Atna a multi-mine production profile and is expected to increase our annual production by up to 30,000 ounces of gold," states James Hesketh, President & CEO.

Aura Silver Resources Inc.

Aura Silver Extends Silver Zone to over 300
Meters - Encounters Significant Gold Values in Limestone

       MANOTICK, ON, June 16, 2010 - Aura Silver Resources Inc. (TSX.V: AUU) ("Aura Silver" or the "Company") is pleased to provide results from its ongoing silver and gold exploration at its Higo Blanco project located in the Taviche district, Oaxaca, Mexico. New results include hole HBET-23 with 238.7 grams per tonne (g/t) silver equivalent over 19.3 meters which extends the overall length established for the Higo Blanco silver trend by about 50 meters. A newly discovered gold zone in Hole HBET-24 includes 2.05 g/t gold (Au) over 8.35 meters (including 4.9 g/t over 2.25 meters).
       Drilling to date comprises 27 holes in total (assays are pending for holes HBET-25, -26 and -27) and has been conducted over several square kilometers defined by silver-antimony bearing 'jasperoid' in Cretaceous limestone and gold-arsenic bearing quartz-sulfide stockwork and hydrothermal breccias in altered Tertiary volcanics. The majority of the drilling has been focused along the northwest-trending Higo Blanco corridor over a strike length of about 1,800 meters. Within this strike length, a concealed silicified breccia near the intersection of the Mezcal structure and the Cretaceous limestone/volcanic interface has been tested in several holes over a strike length of about 1,100 meters. In brief, an elongate, southeast plunging hydrothermal breccia with up to a couple percent of pyrargyrite (silver-antimony sulphide) has been partially defined. Additional drilling will be required to define limits to the northwest, southeast and down-dip.
       Assays for hole HBET-23, located about 50 meters southeast from the intercept in hole HBET-16 (26.8 meters at 365.6 g/t silver) which was a 45 meter step out from discovery hole HBET-03 (34.20 meters at 269.7 g/t), intersected 238.7 g/t silver equivalent over 19.3 meters in pyrargyrite-bearing hydrothermal breccias developed in silicified limestone. This is the same environment identified in the other significant intercepts including HBET-02, -03, -11, -16 and -22. Currently, the silver-bearing breccias have been identified over a strike length of about 300 meters.
       Both the gold and silver mineralizing events reflect a robust hydrothermal system. Current exploration is attempting to follow distinct mineralization styles to depth via down-dip step-outs along the Mezcal structure. The ubiquitous presence of hydrothermal breccias, possible phreatic breccias and andesitic dikes along the structure are proving to be useful guides to both silver and gold mineralization.
       About 700 meters along strike and to the northwest, hole HBET-24 was drilled to test the intersection of the Mezcal structure and limestone at depth and below previous drilling (i.e. HBET-15), where both favorable alteration and mineralization were identified (see Press Release #10-01, dated January 18, 2010). Although the hole was lost (at 217 meters) prior to achieving its target depth of 250 meters, the limestone was encountered and contained numerous, narrow andesite dikes. Several silicified zones at the dike-carbonate contacts were identified and contained anomalous gold values (e.g. from 148.65 to 157.0 meters, 8.35 meters with 2.05 g/t Au, including a higher grade intercept of 4.9 g/t Au over 2.25 meters). This is considered to be significant for several reasons: First, gold mineralization (>0.5 g/t Au) has been identified in both broad surface exposures and in drilling over approximately 1,000 meters of strike along the Mezcal structure, but this new zone is significantly more gold-rich, possibly indicating that the gold zone is expanding with depth. Secondly, the gold (arsenic) event is spatially associated with the silver (antimony) event and is developed along the same structural corridor. And thirdly, the andesite dikes are likely tapping deep-seated, metal-bearing fluids which have migrated up along the same faults that controlled the dyke emplacement. The ubiquitous presence of arsenopyrite and stibnite support a high structural position in the epithermal system. Deeper drilling is clearly warranted in this area.
       Additionally, three holes were drilled at the Rosario prospect, located several kilometers north of Higo Blanco to test the geologic structure beneath the old Rosario mine. These holes did not encounter significant vein mineralization. The Rosario vein is one of many silver and gold-bearing veins identified by Aura Silver in the eastern part of the Taviche district. A trenching program is currently underway in order to better define these structures.
       "We remain confident that our drilling program will continue to expand the high-grade silver resource along the Mezcal structure laterally and to depth where we hope to see an increase in gold values", said CEO Robert Boaz.
       Dr. James M. Franklin, P. Geo. is Aura Silver's qualified person (as defined by National Instrument 43-101) and has reviewed and approved the scientific and technical information in this press release.

Aurizon Mines Ltd.

Aurizon's Infill Drill Program at the
Casa Berardi Principal Area Intersects 4.6
Grams of Gold Per Tonne Over 68.0 Meters

       VANCOUVER, BC, June 14, 2010 - Aurizon Mines Ltd. (TSX: ARZ; NYSE Amex: AZK) is pleased to announce results from its surface infill drill program in the Principal Area at its Casa Berardi Mine, in north western Quebec.
       The objective of the infill drill program is to increase the quantity and improve the quality of the mineral resources previously defined in the Principal Area and to provide information for a pre-feasibility study of an open pit for the area, which is expected to be completed by the end of the fourth quarter of 2010. The Principal Area is located approximately 1.0 kilometre east of the West Mine shaft. As of December 31, 2009, the crown pillar of the Principal Area hosts indicated mineral resources of 1.8 million tonnes at 6.2 grams of gold per tonne for 355,000 gold ounces and inferred mineral resources of 0.8 million tonnes at 6.0 grams of gold per tonne for 162,000 ounces of gold.
       The results of sixty-eight (68) holes, of which thirty-three (33) holes have a metal factor of 50 (true width in metres x the gold grade in grams per tonne), or higher are included in this release and are illustrated on the sketch attached. The drilling program totalled 12,803 metres and covered an area of 825 metres along strike, 250 meters in width, and 50 to 200 metres below surface.
       The best results were encountered in Holes CBS-10-366, with 4.6 grams of gold per tonne over 68.0 metres (true width), CBS-10-331, with 6.2 grams of gold per tonne over 43.0 metres (true width), and CBS-10-341 with 7.0 grams of gold per tonne over 38.0 metres (true width).
       In addition, Hole CBS-09-316 returned a high grade of 114.2 grams of gold per tonne over 0.6 metre (true width), 80 metres below surface. "Sixty-six (66) of the sixty-eight (68) holes were successful in intersecting mineralization above the cut-off grade of 1.0 grams of gold per tonne." said Gilles Carrier P. Eng., Principal Exploration Geologist, a Qualified Person as defined under National Instrument 43-101.
       Gold mineralization occurs within multiple lenses located on both sides of the Casa Berardi break and dips slightly to the South. Mineralization is found in veins, stockworks and sulphide rich replacement zones in a volcanic-sedimentary bearing environment. The zones extend for more than 825 metres along the entire length of the deposit.
       "This drill program confirms the previously known strike extension of the Principal Area, as well as identifying new mineralization which may indicate that untapped potential remains possible in all directions," said Mr. Carrier P. Eng.

Outlook

       The results of the infill drill program will be integrated into a new resource estimate which is expected to be released in the third quarter of 2010. An updated block model will be used in the pre-feasibility study to be prepared by BBA Inc., Montreal, Quebec. Additional underground drilling will be conducted during the remainder of the year to verify the down dip extension of the zone.

Quality Control

       Core assays are performed on core sawed in half, with standard fire assay procedures and atomic absorption finition. Certified reference material, duplicates and blanks are inserted in the sample sequence for quality control. Assay checking on pulp and coarse rejects are carried out on approximately 5% of samples. Additional information on Quality Assurance and Quality Control can be found in the 'Technical Report on the Casa Berardi Mine', dated February 9, 2009, which can be found under Aurizon's profile on www.sedar.com Primary exploration assaying was performed at the mine site laboratory and at the Swastica lab in Ontario. The quality control program is performed at the ALS Chemex lab in Val d'Or.
       Drill hole planning, implementation and the quality control program is supervised by Gilles Carrier. Mr. Carrier is also responsible for the scientific and technical information in this news release.

Aurizon and Niogold Enter into Agreement to
Advance the Marban Block Property, Quebec

       VANCOUVER, BC, July 6, 2010 - Aurizon Mines Ltd. (TSX: ARZ; NYSE-Amex: AZK) is pleased to announce the signing of an option and joint venture agreement with Niogold Mining Corporation ("Niogold") on the Marban Block property, located in the Malartic gold camp in the Abitibi region, Quebec, pursuant to which:
       • Aurizon can earn a 50% interest in the Marban Block, subject to underlying royalties, by: incurring expenditures of C$20 million over three years, of which C$5.0 million is a firm commitment to be spent in the first year; completing an updated NI 43-101 compliant mineral resource estimate; making a resource payment equal to the sum of C$30 (or C$40 if the price of gold is then above US$1,560) multiplied by 50% of the number of total gold ounces in the Measured and Indicated resource categories plus C$20 (or C$30 if the price of gold is then above US $1,560) multiplied by 50% of the number of total gold ounces in the Inferred resource category, based on the updated resource estimate.
       • Aurizon can earn an additional 10% interest, for an aggregate of 60% interest, by delivering a feasibility study;
       • Aurizon can earn an additional 5%, for an aggregate 65% interest, by arranging project financing for capital expenditures estimated by the feasibility study to place the project into commercial production;
       • NioGold will be operator during the initial earn-in period and Aurizon will provide input on exploration programs and will become operator after the initial 50% interest has been earned.
       "We are pleased to enter into this agreement with Niogold for the exploration of the Marban Block." said David Hall, Aurizon's CEO. "This is a continuation of our strategy to assemble a portfolio of exploration properties, at various stages of development, to complement our Casa Berardi and Joanna projects and to provide a strong pipeline for future growth."
       "The Marban block covers 3 kilometres of a 500 metre wide favourable gold bearing shear zone punctuated by historic production, current mineral resources and exploration potential. Underground potential can be projected by following down dip extensions like most similar deposits in the Abitibi area. However, the first phase of Aurizon's involvement on the project will focus on additional drilling to extend resources potentially mineable by open pit." said Martin Demers P. Geo., Aurizon's Exploration Manager.
       The Marban Block includes the Gold Hawk, First Canadian, Norlartic and Marban properties and consists of forty-two (42) mining claims and three (3) mining concessions covering 976 hectares in the heart of the Malartic gold mining camp, Abitibi region, Quebec. A December 1, 2009 resource estimate on the Marban Block, included in a report prepared for Niogold dated March 11, 2010 titled "Updated Mineral Resource Technical Report, Malartic Project" by Michael M. Gustin P. Geo., Mine Development Associates of Reno Nevada (the "MDA Report"), reports indicated mineral resources of 598,000 ounces gold plus inferred mineral resources of 361,000 ounces gold. According to the MDA Report, the mineral resources are defined along a three-kilometre segment of the Norbenite-Marbanite fault zone, in and around the former Marban, Norlartic and Kierens gold mines, which are reported to have collectively produced approximately 600,000 ounces gold. The mineral resources that the MDA Report indicates are potentially amenable to open pit extraction and underground extraction are summarised below:

Estimated Open Pit Resources:
       Indicated: 6.0 million tonnes @ 1.6 grams of gold per tonne (303,000 oz) Inferred: 4.4 million tonnes @ 1.3 grams of gold per tonne (179,000 oz) Estimated Underground Resources:
       Indicated: 2.1 million tonnes @ 4.3 grams of gold per tonne (296,000 oz) Inferred: 1.5 millions tonnes @ 3.9 grams of gold per sonne (182,000 oz)

       A 0.5 grams of gold per tonne cut-off grade was applied to tabulate diluted resources lying within 200 meters vertically from the surface. These resources can reasonably be considered available for potential open-pit extraction and conventional mill processing. A 2.5 grams of gold per tonne cut-off grade was applied to tabulate the deeper undiluted resources lying more than 200 meters vertically below the surface. The higher-grade cut-off for the deeper mineralization is chosen to capture mineralization potentially available to underground extraction and conventional mill processing.
       The MDA Report is available under Niogold's profile at www.sedar.com.
