Geotech of Ontario has been engaged by Micrex Development for completing an air-borne VTEM magnetic and electromagnetic geophysical survey at the Deadwood-Sunburst property in New Mexico. This property has enclosed the previous Deadwood Mine and its surrounding region.
The survey’s geophysical information will be added with the previous property data and will help for upcoming drilling campaigns. The company is expecting that the survey may be completed before this month end. It will announce the further data when it becomes available.
A wide constant vein system developed the early Deadwood mine and this system joins in the property’s south portion. A minimum of two shafts up to a depth of 180 m, many level drifts and strike of up to 300 m length were developed at Deadwood. The previous reports have shown that the material taken out from the mines are graded at around 0.127 oz/t gold, 6.96 oz/t silver.
During 2007, the company drilled a single hole, DW07-01 to a depth of 189.28 m at Deadwood. The hole was meant to undercut the previous mineralization present at the deadwood mine. The planned target depth was not achieved, because of the difficulties in the drill program. Micrex intersected 0.49 g/t gold and 28.19 g/t silver over 65.38 m in the hole DW07-01. The hole soon ended in the vein or fault zone and the mineralization may be exposed at depth.
Micrex cut well-grained, dispersed acanthite-argentite, chalcopyrite, galena, pyrite, and pyrrhotite in brecciated or silicified volcanic rocks, and calcite or quartz veins in the drill hole DW07-01. Amethyst or fluorite was present in numerous breccias and veins and calcite’s box-work textures. This interval has shown the system’s capacity of housing wide low-grade mineralization of gold and silver.
Dahrouge Geological Consulting of Alberta has been held by the company to direct this project.
