Chase Mining intersects shear zone of around 150 metres at Lorraine Mine Gold Project

An extended 6-hole diamond drilling program for 2,928 metres has been completed targeting gold mineralisation at the project in Quebec, Canada.

Chase Mining Corporation Ltd (ASX:CML) has intersected a well-developed shear zone of around 150 metres in diamond drilling targeting gold at the Lorraine Mine Gold Project in southwest Quebec, Canada.

This builds on a highly encouraging series of results returned from the six-hole program for 2,928 metres, which has now been completed.

Well-developed shear zone

The intermittent well-developed shear zone in hole CM-20-06 drilled about 300 metres west of the No 1 drill pad totals around 150 metres in width from about 296 metres to 450 metres downhole.

It contains several wide zones of intense silica-carbonate alteration, with quartz veining and sulphides.

Chase’s diamond drilling intersected the original Footwall Contact Target Zone (FCTZ) and the newly discovered silica-carbonate alteration/breccia zones with sulphides in all six holes.

Targeting gold

This program was targeting the gold (plus silver and possible copper) mineralisation reported from historic sampling and limited drilling associated with the 6-Level development of the Lorraine Nickel Mine.

An initial program of four holes planned for 1,570 metres was increased and was successfully completed overnight with six holes drilled for a total of 2,928 metres.

Program extended

The additional drilling followed a 103-metre extension of hole CM-20-02 to test the deeper prospectivity following an intersection of a footwall breccia zone in CM-20-01.

Minor visible gold associated with intense silica-carbonate alteration in hole two was intersected at a greater depth and as a result the company deepened the remaining holes and re-entered hole CM-20-01 to deepen it.

Quartz-sulphide veining and brecciation was intersected in all holes in several zones to about 500 metres depth, which was the maximum depth of drilling.

This is 75-100 metres into the footwall basalts to the Lorraine nickel-copper massive sulphide body and east of and below the mining void.

Historic intercept

Historic underground drilling from the ‘west end’ of the 6-Level drift returned a narrow gold intercept of 1.5 metres at 1.72 g/t gold in ‘altered basalt’ with quartz-carbonate-epidote veins with disseminated pyrite and chalcopyrite.

This was approximately 200 metres west of hole CM-20-04 at the same level.

To test this, hole CM-20-06 targeted the possible continuation of the FCTZ and was drilled on to test the footwall basalt sequence 200 metres west of the Lorraine Nickel Mine.

As well as intersecting the FCTZ at about 175 metres to 186 metres and several siliceous alteration zones to 296 metres, the hole then intersected an intermittent well-developed shear zone from around 296 metres to 450 metres downhole.

Additional potential

Samples from the program will be submitted for gold analyses following completion of the detailed core logging and sampling, which is expected to be finalised later this week.

Discovery of the deeper footwall alteration zone/s in all holes including minor visible gold in hole-2 which is separate from the original FCTZ opens additional potential for gold mineralisation to be hosted at the Lorraine Mine site.

The visual success of Hole CM-20-06 about 200 metres at depth west of hole CM-20-04 adds potential size to the project.
