Mazorro and Adventure Gold Report Lapaska Phase 1 Drill Results Confirming Bulk Tonnage Potential of Shallow Gold Mineralization/Central Zone Strike Length at 500 Metres With Open Extensions

OTTAWA, ONTARIO--(Marketwire - July 21, 2011) - Mazorro Resources Inc. (TSX VENTURE:MZO) (FRANKFURT:JAM) ("MZO" or "Mazorro") and Adventure Gold (TSX VENTURE:AGE) ("AGE") are pleased to to report final results from the phase 1 surface drilling program on the Lapaska Gold Property (the "Property"). A total of eight (8) holes were completed for a total of 3,117 metres. The Property, located 20 km east of Val-d'Or in the prolific Abitibi Greenstone Belt, is wholly-owned by AGE and under option to MZO (see agreement in press release dated December 15, 2010). The first two holes of the phase 1 program were previously released and highlighted gold intersections of 1.0 g/t Au over 103.4 metres for hole LP-11-16 and 1.2 g/t Au over 156.9 metres for hole LP-11-17 (see press release dated June 16, 2011).

The best gold intersections in the Lapaska Central Zone ("LC Zone"), in core length, for the remaining six holes yielded values of:

• Hole LP-11-18: 1.0 g/t Au over 56.0 metres, including a section grading 11.6 g/t Au over 3.3 metres, within a gold halo of 0.5 g/t Au over 200.8 metres;

• Hole LP-11-19: 1.5 g/t Au over 10.5 metres, 1.3 g/t Au over 11.5 metres and 2.6 g/t Au over 3.3 metres, within a gold halo of 0.5 g/t Au over 111.1 metres; and

• Hole LP-11-22: 1.0 g/t Au over 32.3 metres, including a section grading 6.8 g/t Au over 2.7 metres, within a gold halo of 0.4 g/t Au over 101.8 metres.

The gold system at the LC Zone presently has a confirmed strike length of approximately 500 metres but remains open in several directions. Hole LP-11-22 indicates a north-south extension in the west area of the gold system, north of LP-11-17. Additional drilling in the next phase will be designed to extend the zone east-west and define the north-south extension in the west part of the deposit.

"We are now planning a second phase drill program of 4,000 metres, with our partner AGE, which we believe will further highlight the bulk tonnage potential at Lapaska", stated André Audet, President and CEO of Mazorro Resources Inc.

Final results of the phase 1 drilling program are presented in Table 1. Also a surface map view of the recently completed drilling (see Figure 1: http://media3.marketwire.com/docs/Surface-Map-PR-July-21-201-1.pdf) and a longitudinal section (see Figure 2: http://media3.marketwire.com/docs/Surface-Map-PR-July-21-2011-2.pdf) are presented. The diamond drill holes LP-11-18 and LP-11-19 oriented at 280º and dipping at -52º were drilled perpendicular to the strike of the vein system in the LC Zone. Holes LP-11-20 to 23 were drilled in the same direction and tested the lateral north-south extension of the veins system.

Gold mineralization in the LC Zone is associated with a network of quartz-carbonate-tourmaline-pyrite veins and veinlets dipping to the east, largely hosted in a magnetic silicified felsic volcanic unit. Gold mineralization is similar to that observed at the Sigma II former producing gold mine, located 5 kilometres to the east. Measurements taken with a core orientation tool indicate the presence of two vein systems. The first system is N-trending and the second one is ENE-trending. A stacking of veins spaced every 0.5 to 2.0 metres is observed in the best mineralized zones. These holes were entirely assayed from top to bottom in order to fully characterize the gold content of the LC Zone. Historical drill holes were not fully assayed.

* Reported gold intersections are measured along the hole and are close to the true thickness of the mineralized zones.

Phase 2 drilling program

A phase 2 drill program, totaling approximately 4,000 metres in 12 holes is being designed to test the east-west extension and the lateral north-south extension of the LC Zone and to drill the West zone. Proposed drilling is presented on the surface map (see Figure 1: http://media3.marketwire.com/docs/Surface-Map-PR-July-21-201-1.pdf). Seven (7) holes are planned to test the LC Zone near surface extensions, three (3) holes for the deep extension (below 200 metres) of the West Zone and two (2) holes for the West Zone close to the extension of the 2010-11 Eloro new discoveries on the Simkar property.

The Lapaska Property

The Property is favourably located between the past-producing Sigma II gold deposit to the east (161,300 ounces at 2.7 g/t Au: MRNF - SIGEOM Database), which was mined by open pit method, and the Simkar gold deposit to the west (NI 43-101 inferred resource of 105,000 oz at 5.3 g/t Au: Megastar – MDV: TSX-V, September 2008). The Property contains three significant gold-bearing zones: the Lapaska Central, West and Lourmet zones and is also strategically located along the prolific Cadillac-Larder Lake Gold Break, a regionally extensive structure that is spatially related to numerous gold mines.

A NI 43-101 compliant resource estimate was completed for Mazorro by InnovExplo (March 22, 2011) on the Lapaska Central Zone prior to phase 1 drilling. Table 2 below shows the variations with respect to metric tonnes, gold ounces and grades for various cut-off grades in the Inferred Resources of the Lapaska Central Zone deposit.

Cut-off Grade (g/t Au)	Tonnes	Avg. Grade (g/t Au)	Ounces of Gold
0.5	2,143,702	1.15	79,324
1.0	864,563	1.81	50,396
2.0	219,590	3.14	22,197

Jules Riopel, P.Geo., Vice-President Exploration and Acquisitions of Adventure Gold Inc. is acting as the "Qualified Person" as defined by NI 43-101 and has reviewed this press release and has supervised the drilling program. Assay samples were taken from NQ core sawed in half, with one half sent to AGAT Laboratories in Mississauga, Ontario, a commercial laboratory, and the other half retained for future reference. A strict QA/QC program was applied to all samples, which included mineralized standards and blank samples for each batch of 25 samples. The gold analyses were completed by fire assay with an atomic absorption finish on 50 grams of material. Repeats were carried out by fire assay followed by gravimetric testing on each sample containing 3.0 g/t gold or more. Total gold analyses (Metallic Sieve) were carried out on samples that showed a great variation in gold content or the presence of visible gold.
