"PLEASE CLICK BELOW ON A MINING CAMP"
The La Virgen Valley Production Camp currently encompasses two high grade operating silver mines, Chivo Mine - Largest & Highest Silver Grade Mine in the district and the San Ramon Mine - High Lead & Zinc Grade. Ore is transported to the 500 tpd processing plant in the Guadalupe mining camp for processing which currently operates at 343 tonnes per day (tpd).

Chivo Mine
Chivo is the largest and highest grade producing mine in the district. It is the second mine put into production by the Company's team. Chivo was identified as a high priority exploration target in late 2005 when sampling in an old small mine working and on surface returned high grade values of 1,095g/t Silver over 1.25m TW and 2,640 g/t Silver over 0.85m TW respectively. In 2006, IMPACT began drilling and by 2008 had completed 46 drill holes outlining the high grade Chivo Silver Shoot over an area of 300m long and 200m deep. Commercial mining began in January 2008. The zone remains open for expansion in all directions. Currently, Chivo provides the majority of the production.

San Ramon Mine
San Ramon is located 1.3 km south of the Chivo Mine and supplements production from Chivo The main mineral shoot is typically 60m long by 3m wide and hosts high grade silver ores.
Mining continues to expand at San Ramon as the Company also developed underground access to a parallel structure, the Chaparrita Vein. During the third quarter of 2009, a new wide zone of silver-rich stockwork breccia style mineralization was discovered on level 5.5 and is expected to increase production at the mine.
At San Ramon two drill programs have taken place mainly prior to intial production. The holes were drilled to both determine the size of the San Ramon Mine and to plan for future mining. The most significant results returned from both programs include the following:

EXPLORATION
Cometa Navideno/Santiago Vein
Earlier sampling of the historic Santiago mine workings by IMPACT returned average values of 235g/t silver and 0.31g/t gold across 0.9m (TW) ranging up to a high of 1,320g/t silver and 0.99g/t gold across 0.3m (TW). Earlier results from this Shoot reported a median value of 680g/t Ag and 0.3g/t Au over 0.90m to a high of 1,128g/t Ag and 0.2g/t Au over 1.9m. Two holes were drilled here in 2005. One of the holes returned 7.26% zinc, 7.45% lead, 75g/t silver and 0.59g/t Au across 0.65m about 120m below the old mine workings.
Los Reyes Zone
Finding other clusters of large veins situated next to a producing mine allows IMPACT to readily and quickly integrate them into production. An example is the Los Reyes Zone, located 600 metres east of the Chivo Mine. It is a thick vein system that trends parallel to the silver-rich Chivo Zone. Highlights from an 11-hole drill program include the following:
