Scorpio Mining Corporation announced that Quantec Geoscience Ltd. has completed a 48-line kilometre Titan-24 DCIP survey centered over the San Rafael area of the Platte River Project in Sinaloa, Mexico.
The survey was initiated in June of 2010 and covered a 3 x 3 kilometre area using 100-metre dipole spacing on 200-metre spaced lines. The preliminary results of the survey show high chargeability and low resistivity anomalies lying east and northeast of the drill-defined San Rafael massive sulphide deposit. The geophysical response correlates well with that of the San Raphael, and is at comparable depths of generally 50 to 200 metres below surface. Interpretation suggests however, that these are somewhat larger anomalies with stronger chargeability than San Rafael, and extend to depths in excess of 500 metres. The anomalies, which extend roughly 300-1000 metres to the northeast of the San Rafael, are considered to be high priority drill targets and will be drill tested immediately. Several other geophysical anomalies have been interpreted from the survey and will be evaluated and prioritized as results from initial drilling are received. A 3,000-metre drill program has been approved for initial testing and a drilling contract has been awarded. Drilling is expected to begin by the first week of Sept 2010 with initial assay results expected four weeks thereafter. HQ and NQ size diamond drill coring will test to 500-700 metre depths. A petrographic and mineralogical study of the San Rafael related mineralization types (San Rafael Upper zone, Main zone, 120 zone and El Cajon deposit) by Eva S. Schandl, Ph.D., has determined that the San Rafael Main zone mineralization is comparable to the uppermost part or distal part of volcanic massive sulphide “VMS” type deposits. The Upper zone sits just above the Main zone, with the 120 zone feeding into the Upper and Main zones. The El Cajon zone sits on the periphery of the 120 zone. NI 43-101 compliant mineral resources have been estimated for all of these zones over a relatively small area and at shallow depths (see news release dated Oct 15, 2009). All of these zones have been drilled out at 25-50 metre drill spacing and remain open to expansion. In addition, preliminary metallurgical work has been completed on the Main and 120 zones and indicates normal metal recoveries. Peter J. Hawley, CEO reports, “Given the amount of mineralization outlined to date over a relatively small area of the San Raphael deposits, this newly identified, larger and more intense geophysical anomaly presents a very promising drill target. In addition, the geological and mineralogical setting supports a potential VMS setting, which bodes well for additional discoveries in the area.” |
