Passport Metals Inc. Identifies Copper Manto at Gilda Copper – Gold Propertyadmin
Passport Metals Inc. announce that it has identified a copper bearing manto on its Gilda Joint Venture Property located 25 kilometres north east of the regional mining centre of Copiapo in Region III, Chile. Phase I exploration consisted of excavator trenching, road building, mapping and sampling. Preliminary bedrock chip and grab sampling in a newly discovered manto returned copper grades from 0.475% to 3.454% from a total of 5 samples.
The manto lies on a flat to gentle slope and bed rock exposure is limited. There are two small exposures at surface and an adit. Two bedrock chip samples were taken from the adit. They ran 2.271% Cu over 0.75 metres and 3.159% Cu over 0.75 metres. The manto is relatively flat lying and is about 1 metre wide in the adit.
Grab samples were also collected from the adit and from oxide material next to two surface exposures that are approximately 45 metres southwest and 60 metres northeast of the adit. The grab sample from the adit ran 3.454% Cu. Two grab samples from the oxide material ran 1.815% Cu and 0.475% Cu respectively.
The area hosting the manto is cut by a number of vertical quartz veins and faults, suggesting the manto could be considerably thicker in the areas that cross the vein structures.
Passport plans to open the manto both along strike and down the relatively flat dip at regular intervals with an excavator. All excavator trenches will be mapped and sampled in preparation for drilling of the high priority target areas within the manto in the 4th quarter of 2008.
