Jake Creek, Nevada
DataLocation: Between the north Carlin Trend & Getchell Trend, North Central Nevada
Size: 14,405 acres
SummaryEvolving Gold holds an undivided, 100% interest in the Jake Creek project. The Jake Creek property is approximately 14,405 acres and is located in the western foothills of the Snowstorm Mountains on the edge of the Northern Nevada Rift. It is between the north Carlin & Getchell Trends, approximately 9km east of Newmont's Twin Creeks Mine.
Two drill programs have been completed, one in November 2010 and the second between August and December 2011. Gold mineralization generally occurs in the Tertiary volcanic rocks above the unconformable contact with Paleozoic sedimentary rocks. Gold-bearing zones contain elevated concentrations of arsenic-selenium-antimony-mercury-silver, typical of other well-documented epithermal, volcanic-hosted gold systems in this region. Mineralization is associated with adularia and clay alteration, and has a low silver to gold ratio like that at the nearby Ken Snyder and Sleeper deposits in Nevada.
JC-013, the eastern-most hole, encountered multiple zones of banded quartz-sooty pyrite epithermal veins associated with sulfidized basalt dikes. The gold system exceeds a diameter of 550 meters, and remains open to the north, south and east. Drill results are summarized below.

Other Exploration Activities
- A mercury vapor survey was completed in 2008. JC-001 and JC-005 were located based on mercury vapor and regional gravity anomalies.
- A combination detailed and semi-regional gravity survey was completed in late 2010 to follow up the mineralization in JC-005.
- Assays of 2011 surface samples collected from a portion of the project area known as the Panorama prospect returned anomalous gold values, establishing the area as a new exploration target.
- An airborne magnetic survey was completed in Spring 2012. The data set revealed features of interest that will be targeted in future drilling campaigns.
Future PlansPermits are in place for three drill pads at Panorama and for two additional pads near the original discovery area. Angled holes are planned at Panorama to intersect quartz veins exposed at the surface. Angled holes are also planned to the east and southeast of JC-013 to test features revealed in gravity and aeromagnetic data and to test the extent of epithermal veins and basalt dikes.
2010-2011 Summary of Results:
- Drill hole JC-005 intersected 45.7 meters at 0.97 gpt Au (150 ft at 0.028 opt Au), including 28.9 meters at 1.33 gpt Au (95 ft at 0.039 opt Au), and 1.5 meters at 11.3 gpt Au (5 ft at 0.330 opt Au). Drill hole JC-001 intersected multiple zones of anomalous gold, with grades to 0.36 gpt Au (0.011 opt Au) from 380 meters down hole to the end of the hole at 700 meters. Holes JC-002 through JC-004 remain to be drilled.
- The high grade intersection in drill hole JC-005 is at a depth similar to that mined at the nearby Ken Snyder mine in the Midas district.
- Drill holes JC-001 and JC-005 tested geophysical and mercury vapor anomalies.
- The Jake Creek property is located on the western margin of the Northern Nevada Rift in a relatively unexplored area of north-central Nevada. The Twin Creeks mine (Newmont Mining Corp.) is approximately nine kilometers west of Jake Creek, and the Clover property of Atna Resources is contiguous to the southeast.
- Volcanic hosted gold mineralization at Jake Creek is associated with silicification, adularia and clay alteration, typical of epithermal gold deposits, and has a low silver to gold ratio similar to the nearby Ken Snyder and Sleeper deposits in Nevada.

All drill hole averages are weighted averages, weighting each assay interval according to the core length for that assay interval. All assay intervals are included in the average, with no bottom cut-off. True widths of mineralization in these drill holes, at this stage of exploration, are not precisely known. Gold assays were completed by SGS Canada Inc. in Toronto, using a 30 gram charge, fire assay, with an ICP finish.
