ON EXPLORATION

  • Azure Minerals Ltd. plans to start a 100 diamond hole, 5,000 m drill program at its Oposura property in Sonora during October, once the permits have been received. “Drilling by previous explorers of 85 surface holes tested the mineralised zone over an area of approximately 1,400m (east-west) x 400m (north-south) (see Figure 1). Early drilling by Azure will twin some of these historical holes to assess whether they can be used in defining the deposit and estimating the mineral resource”. With all the historical and recent work compiled Azure has derived an exploration target of 2.5 M tonnes @ 10% – 12% Zn+Pb.
  • Prospero Silver Corp. has received from SEMARNAT the permit to drill the Petate property in Hidalgo. Drilling is to start on September 17th, 2017, with 12 holes to test four targets: Apartadero SE, Apartadero Central, Tajo and Petate #3. “High-level epithermal alteration is exposed over a 5×4 km area with highly anomalous gold and silver hosted in extensive outcrops and float of steep to strata-bound jasperoid.”
  • Radius Gold Inc. released high-grade channel sampling results from the recently optioned Amalia property in Chihuahua. At the Campamento zone, where a 150 m by 300 m zone of intense silicification, brecciation and stockwork veining has been mapped, results include 62 m @ 0.43 g/t Au, 98 g/t Ag; 14 m @ 1.47 g/t Au, 167 g/t Ag; including 7 m @ 2.37 g/t Au, 239 g/t Ag.
