The two holes penetrate variable microdiorite, minor monzonite or monzodiorite, diorite, tuff or local bedded tuffaceous sediments. Variable textures in the generally fine-grained units exhibit episodic intrusion events, intrusion breccias, hornfelsed host rocks, many crackled and all overprinted by chloritic or K-feldspar dominant alteration assemblages. Brittle brecciation generates a chaotic fragmental texture and late carbonate veins, veinlets, microfractures or stockwork occur throughout most rock types.
Below 5 to 10 m depth both holes 46 and 47 contain 1 to 2% pyrite. An 2 mm filigree grain of electrum occurs in a massive very fine-grained K-feldspar vein in hole 46 at 29.0 m otherwise gold is not visible in the remaining portions of the holes. K-feldspar also occurs as irregular patches or fillings, selvages, veins or dikelets surrounded by pervasive chlorite alteration where both assemblages normally contain disseminated pyrite, blebs or cut by pyrite fractures. In the higher-grade zone (>2 gpt Au) better grades are associated with common K-feldspar-pyrite alteration whereas chlorite dominate alteration ranges from >0.1 to 1 gpt Au. Blebs of chalcopyrite occur sporadically in the elevated gold zone particularly in the deeper hole 47 and may indicate deeper, more typical porphyry Cu-Au mineralization.
The style of the
Future drilling will be oriented southeast to test the depth extent of the grade and width beneath the zone and sub-parallel sections on either side of holes 46 and 47 to test the lateral extension of the gold zone. Petrology on select drill core and preliminary metallurgical testing on drill rejects will also be completed in the coming weeks.
