San Marco Resources Inc. (TSXV:SMN) announced the receipt of preliminary results of a petrographic study completed on a 1 meter x 2.5 meter panel sample taken from the old Tompiate underground workings on the Angeles property in the Sonora State, Mexico.
As quoted in the press release:
A representative cut of this sample was sent to ALS Chemex for assaying and results are:
• 11.20 g/t gold; 54.8 g/t silver; 1.98% copper and 4.21% combined lead/zinc
Early mineralogical results indicate native gold exists as very fine particles (free and associated with tiny quartz crystals), also copper (chalcopyrite and copper oxides chrysocolla and malachite), lead (galena and Pb oxide wulfenite) and zinc (sphalerite and Zn oxide smithsonite).
