Drill-testing of a copper-molybdenum porphyry system has wound down at General Minerals’ (TSE) Vizcachitas property, 80 km northeast of Santiago, Chile.
In a previous drill program, all five holes encountered copper and molybdenum mineralization. One hole returned an intercept of 66.5 metres averaging 0.74% copper and 0.066% molybdenum, while a second returned 30.75 metres averaging 0.92% copper and 0.016% moly. The remaining holes intersected copper grades ranging from 0.1% to 0.3% over widths of up to 300 metres.
The known area of potassic and quartz-sericite alteration measures 3 sq. km.
Bulldozer trenching has exposed a leached cap of copper oxide mineralization and breccia-hosted copper sulphide and molybdenum mineralization.
The trenched showing, called the South zone, lies 650 metres south of the previous limit of known mineralization.
>From two South zone trenches, General Minerals has taken 82 continuous, 1-metre channel samples, with oxide material values ranging up to 0.62% copper and 114 parts per million (ppm) molybdenum. Typical copper values range between 0.1% and 0.3%.
Oxide material values from 22 continuous channel samples averaged 0.21% copper and 54 ppm molybdenum, while 44 continuous channel samples from partially leached hydrothermal breccia averaged 0.15% copper and 100 ppm molybdenum.
Current drilling will determine the nature and extent of the mineralization.
