Exploration at Hargraves is focused on increasing resources and preparation of a mining plan for commercial development.
Encouraging drill hole results returned from earlier work at the North Big Nugget Hill Deposit, part of Hargraves, are being followed up with deeper drilling and exploration along strike.
Stage 2 drilling will test the mineralisation to 150 metres vertically below surface and to the north where the system remains open.
Ongoing drilling and new modelling of high grade zones could lead to an increase in the current Resource at Big Nugget Hill. Currently, it sits at 2.2 Mt at 3.1 g/t Au for 221,000 ounces of contained gold.
Stage 1 drilling at Big Nugget Hill
Fifteen diamond drill holes totalling 1,642.8 metres were completed in Stage 1 drilling at the North Big Nugget Hill Deposit.
Drill hole results were received for all holes. The drilling program is testing the potential for shallow, bulk tonnage-style gold mineralisation first suggested by a diamond hole drilled in 1988 which returned 211 metres at 0.5 g/t from 30 metres, including 23.5 metres at 1.1 g/t from 30 metres.
Gold mineralisation occurs in a zone of multiple quartz veins and breccias that trends northerly and dips steeply west. The zone is persistent along strike and dip and is interpreted to extend to surface.
So far it has been traced for 300 metres north of the Big Nugget Hill gold resource and remains open to the north and at depth.
Detailed structural modelling of the high grade zones of the Big Nugget Hill deposit by KRC Mining Consultants is in progress.
Initial results have indicated that the mineralisation is well-controlled and far more persistent than previously interpreted.
It is expected that this work will extend the Big Nugget Hill resource and provide infill drill targets. It will also provide a more robust framework for resource modelling and mine design.
Managing director of Hill End Gold, Philip Bruce said, "Drilling at the north end of the Big Nugget Hill deposit continues to intersect open-ended wide zones of persistent bulk tonnage-style gold mineralisation at shallow depth.
Recent detailed structural modelling done as part of this program has revealed a far better continuity of the high grade zones in the Big Nugget Hill Deposit than previously interpreted.
This will lead to a new resource model for the Big Nugget Hill deposits on which a new resource estimate can be based."
Current JORC Resources are measured at 3,995,000 tonnes grading 5.4 g/t Au for 557,000 ounces of gold that are located at Big Nugget Hill, Hawkins Hill / Reward and Red Hill.
