The Copper Queen prospect has no exposed mineralization at the surface but contains copper sulfide skarn at depth and an incompletely confirmed copper-molybdenum sulphide porphyry system at greater depth. The Champion and Longshot Ridge prospects, however, have numerous widespread exposures of copper skarn mineralization, both in surface outcrop and abundant old mine workings. The majority of recent exploration efforts on the New York Canyon property have focused on the extensive oxide copper skarn mineralization at Longshot Ridge. This mineralization is the subject of the current report. The copper mineralization and associated alteration at Longshot Ridge are products of an extensive copper-rich skarn system formed in carbonaceous sediments of the Luning, Gabbs and Sunrise Formations. Small amounts of copper occur also in stockwork veinlets in felsic porphyry intrusive sills and dikes. The copper mineralization consists almost entirely of secondary copper minerals, principally malachite, azurite, chrysocolla and copper wad, in order of abundance. Additionally, some copper-rich limonite (goethite) has been reported. The oxide copper minerals apparently are the products of supergene weathering and oxidation of primary copper sulphide minerals present in the original skarn. Because limestones tend to buffer any solution carrying copper in the supergene environment, copper can be enriched as much as 300 to 400 percent by this supergene weathering process. Oxide copper deposits formed in a similar manner in many copper districts throughout the southwest US, have contributed substantially to the copper produced from the associated primary copper deposits in these districts. About 90 percent of the Longshot Ridge mineralization is within the two upper units of the Gabbs Formation. Drilling reveals that the strongest, thickest and most continuous mineralization occurs in a NE-trending zone, 200 feet wide by 1300 feet long, which is crossed by two NW-trending structurally-controlled high grade zones, each about 100 feet wide and from 400 to 700 feet long.

This hole ended in strong copper mineralization. Drill hole 04-03 was a vertical hole drilled to a depth of 433 ft. While drilling the hole, it was recognized that previous drill holes in the vicinity had encountered significant mineralization at the contact of the overlying oxidized Gabbs Formation and the underlying Luning Formation, and this hole was exteneded to test this target. This drill hole (04-03) intersected 370 ft. of 0.314% copper (from 25 ft. to 395 ft.) including 140 ft. of 0.549% copper (25 ft. to 1.65 ft.) and 35 ft. of 0.709% copper (70 ft. to 105 ft.)
