Other than the Donnelly, GJ and North (Camp) deposits, this is the most advanced copper-gold porphyry target on the GJ property.
Geochemical work, geological mapping, ground magnetic and shallow IP geophysical surveys have outlined a 5 km long by 850 m wide, open-ended structural corridor that has been investigated by prospecting, mapping, soil sampling and geophysics, and limited shallow drill testing over the easternmost 1.6 km.
Between 1970 and 1991, thirteen holes totaling 2,878 m were drilled in the Main and Cliff zones. At least 4 were abandoned due to bad ground; however the rest had long-low-grade porphyry Cu-Au intersections including:
- DDH 70‐2: 148.13 metres grading 0.13% Cu
- DDH 70‐3: 139.60 metres grading 0.07% Cu
- DDH 70‐4: 322.78 metres grading 0.13% Cu
- DDH 70‐5: 300.84 metres grading 0.12% Cu
- DDH‐90‐Q01: 87 metres grading 1,067 ppm Cu (0.11%) and 21 ppb Au and 12 metres grading 1,162 ppm Cu (0.12%) and 912 ppb Au
- DDH‐90‐Q02: 16.5 metres grading 1,168 ppm Cu (0.12%) and 16 ppb Au and 12 metres grading 1,435 ppm Cu (0.14%) and 140 ppb Au
- DDH 91‐1: 69.0 metres grading 0.276% Cu
- DDH 91‐2: 63.0 metres grading 0.190% Cu
- DDH 91‐3: 72.0 metres grading 0.140% Cu
Although historic, shallow drill results are low-grade, interpretation of geology, alteration, magnetic and IP geophysical results suggests a potential higher-temperature, higher-grade zone coincident with a magnetic and IP chargeability high may exist at depth below previous Main Zone drill holes.
Two deep holes (550 and 650 m depth) are recommended to test the target beneath the main zone.
Limited exploration work west of the existing geophysical surveys has extended the length of the QC porphyry system a further 1500 metres west where it remains open.
Rock and silt sampling in this West Zone portion of the QC copper-gold porphyry target has yielded significant gold values with indications that the area has a higher Au:Cu ratio than observed at the Main-Cliff Zone.
It is recommended that the soil sampling, prospecting and IP survey coverage be extended to the south and west to cover the remaining portion of the structural corridor, including the gold-rich West Zone area.
