Copper Hill Drilling Update – GCHD472, GCHD473 & GCHD474
- GCHD472, on section 5400N and completed at 486 metres, contains many well-mineralised intervals within a broad zone of 426 metres grading 0.39% copper and 0.39g/t gold.
- The 426 metre mineralised zone is defined by a 0.2% copper cut-off grade
- GCHD473, to test extensions to the high-grade hole GCHR107 on section 5450N, has been completed at 507 metres having drilled well mineralised ‘Crowded’ Tonalite Porphyry containing chalcopyrite in extensive quartzmagnetite ‘M-veins’, quartz-chalcopyrite ‘B-veins’ and sheeted quartz veins.
Assays are awaited.
- Drilling GCHD474, on section 5300N, commenced on Monday, 20th October.
GCHD472 returned high copper and gold grades in the central section of Copper Hill down-dip from previous high grade core and reverse circulation drilling results.
PQ and HQ core sample assays have been returned from the ALS laboratory in Orange.
Substantial, higher grade intervals, using a 0.4% copper cut-off grade, are set out below. All results are tabulated in full at the end of this report:
The porphyry copper-style mineralisation occurs within micro-tonalite and ‘crowded’ tonalite porphyry as laminated quartz-magnetite vein stockworks with chalcopyrite, pyrite and gold.
The central zone from 30 to 308 metres includes, using a 0.2% copper cut-off grade, a higher grade zone of 56 metres grading 0.62% copper and 0.53 g/t gold from 32 metres downhole, and 78 metres grading 0.54% copper and 0.74 g/t gold from 110 metres downhole.
