The drillhole included higher grade assay intervals including 23.4 metres grading 2.12% copper, 0.7 gram gold and 6.2 grams silver (2.51% copper-equivalent); 64 metres of 1% copper, 2.17 grams gold and 2.9 grams silver (2.12% copper-equivalent); and 22.5 metres of 1.15% copper, 2.95 grams gold and 3.6 grams silver (2.67% copper-equivalent).
