Newcastle Minerals has completed a 1,050 m diamond drilling program, totaling four holes at its Chester Project, which is situated in northwestern Ontario, Canada.
The company has encountered intermediate intrusive rocks that are mainly hornblende diorite and rarely intermediate to mafic volcanics at all the drilled holes. In general, the hornblende diorite was immense, medium green-grey, medium-to coarse-grained and has about 40% to 50% feldspar and 50% to 60% hornblende. The intermediate intrusive rocks were extremely fine grained and generally amygduloidal for numerous metres at the lower and upper contacts with the immediate intrusive and through the fine-to medium-grained that is immense in units’ core.
There were weak sulphide mineralization existing all through the rocks that was encountered and was typically connected with variable fracturing and alteration degrees.Chalcopyrite, pyrite, pyhrrotite and possibly sphalerite are the major sulphides encountered normally in trace amounts rarely up to 1% or 2% over some metres.
Alteration includes mainly variable sercite, quartz-carbonate, and chlorite alteration and veining with weak to moderate irregular fracturing zones with local brecciation. Moreover, local potassic and hematite alteration was present along with the quartz-carbonate veining.
The company has sent 221 cut drill core samples in total to Accurassay of Thunder Bay, Ontario for assaying. It has executed the drilling program under the direction of Mr. Des Cullen, who belongs to Clark Exploration Consulting of Ontario and Chenier Diamond Drilling of Sudbury, Ontario carried out the drilling.
