In 2002, Nevada Pacific Gold re-staked the property and completed additional geologic mapping and rock chip sampling. Gold, now Mc Ewen Mining, acquired Nevada Pacific's interest in the prospect by means of a merger, but conducted little additional field work and allowed their claims to lapse in September 2012.

In 2005, they drilled 23 holes, confirming the style and grade of mineralization in 16 of the holes. Of the holes completed in the three historic campaigns, half intersected more than (30 meters) 100 feet of mineralization averaging more than 0.342 g/tonne (0.010 oz/ton) gold at a cutoff of 0.171 g/tonne (0.005 oz/ton).

All holes intersected long intervals of anomalous material except for two drilled off the range front that did not reach bedrock.

Preliminary cyanide leach analyses indicate the likelihood of favorable metallurgy. - Confirm, delineate, and expand the zone of gold mineralization by core drilling within and adjacent to the area drilled to-date. -- Reconnaissance drilling to explore for additional zones of mineralization within the 1.5 by 1.0 kilometer (0.9 by 0.6 mile) biotite-pyrrhotite alteration zone associated with the polyphase intrusive complex that appears to have caused gold deposition.

Gold is confined to a narrow ±1-foot (0.3 m) wide band in the footwall of the vein, averaging about 1.64 oz/t gold along the length of the tunnel, with several channels across the vein returning assays of more than 100 oz/t gold.
