Gold-Silver Mining Projects New Contract in Nayarit, Mexico
Premium Exploration, Inc. is pleased to announce it has signed contracts for options to acquire 100% of the Rosamorada and Dos Amigos properties, located in Nayarit State, Mexico.
Rosamorada demonstrates good potential to host bulk tonnage gold-silver deposits amenable to low-cost open-pit mining methods. The Rosamorada project consists of 300 hectares at approximately 100m elevation, within two kilometers of the Pan American highway and less than one kilometer from an active rail line. A high-tension powerline crosses the property.
Geological mapping at Rosamorada by Premium revealed quartz veining and stockwork over low hills covering an area 1000m by 300m. Samples were collected from surface outcrops, sub-crops or were composite samples of representative locally-derived float where outcrop as not exposed. Outcrop exposure at Rosamorada represents less than 5% of the claim area. Twenty-five samples were collected from the stockwork zone, of which 13 returned greater than 200 ppb gold, and four returned greater than 20 ppm silver; 12 samples returned greater than 0.5 g/t gold equivalent, and eight samples returned greater than 0.7 g/t gold equivalent, using a 55:1 silver to gold ratio. Gold equivalent grades are calculated using a gold to silver ratio of 1:55 based on recent gold to silver ratios. One float sample, which contained visible sulfide minerals encapsulated in quartz, returned 2393 ppb gold and 437.5 ppm silver (9.7 g/t gold equivalent). Silver values could be understated due to leaching and downward mobilization of silver from the surface.
