MEXICO – The San Antonio gold deposit in Sonora is now believed to contain 300,000 oz of gold, as estimated by sole-owner ZARUMA RESOURCES of Toronto. Measured and indicated resources estimates include material recoverable by both underground (244,000 oz) and open pit (36,700 oz) methods.
The area of drilling is the Realito structure. Estimates of underground measured and indicated resources total 1.74 million tonnes at an average of 4.37 g/t Au, plus an inferred resource of 162,000 tonnes at 3.97 g/t Au. The measured and indicted open pit resources total 551,000 tonnes averaging 2.08 g/t Au; and there is also an inferred resource of 72,000 tonnes at 2.13 g/t Au. In addition San Antonio includes an estimated 6.6 million tonnes at 0.76% Cu.
The current study did not include mineralization at Cerro Sapuchi, located 1 km north of the Realito structure, since no recent work has been completed on that resource. That resource estimate, based on work completed in 1996, was 1.4 million tonnes at 2 g/t Au, containing 89,000 oz of gold, although the calculation was not done to NI 43-101 standards.
A program is being planned to expand the reported Realito resource, where the mineralization strike is open to both the east and west. In addition, regional surface exploration work is continuing in areas of large gold soil, rock chip and geophysical anomalies. Promising targets are located along the Corina-Mina Grande-Cerro Sapuchi trend and between the California and newly drilled Centenario zone of the Realito structure. In the latter area an exploration hole was drilled on an IP anomaly that had been enhanced by remodeling of data, and intercepted several mineralized intervals, including one with 1.35 metres at 8.82 g/t Au close to surface.
