- Pre-production activities at the Williamson open pit in advance of ore production in November 2019, with Williamson then providing the baseload of free milling ore
for the remainder of FY2020.
Production in FY20 will be focussed on free milling ore
bodies prior to Blackham transitioning to Stage 1 of its Sulphide Expansion Project, which is planned to commence production during FY21.
The company president and chief executive officer, Lewis Lawrick, said, 'The execution of these agreements will allow us to proceed as planned with custom milling ore
from our Pine Cove mine at Crew's Nugget Pond milling facility without delay.
The cutoff grade for the mine was about 4.3 kg/t (125 oz/ton) Ag and 40% Pb, and thousands of tons of milling ore
were either discarded or left unmined.
By this time, the 3.68 Moz South Pipeline resource consisted of 50.5 Mt of leach oxide material with an average grade of 0.75 g/t Au, assuming a cut-off grade of 0.34 g/t Au; 16 Mt of oxidised milling ore
averaging 3.77 g/t Au at a cut-off of 1.7 g/t; and 2.9 Mt of carbonaceous material with an average grade of 5.5 g/t Au at a cut-off grade of 3.4 g/t Au.
Perth, Australia (ABN Newswire) - Blackham Resources Ltd (ASX:BLK) (FRA:NZ3) (OTCMKTS:BKHRF) Current operation focused on safely and consistently mining & processing 2Mtpa free milling ore
at reduced costs
The technical report shows that Escondida ore hosts grades more than 3.4 g/t gold (g/t Au) as milling ore
. Using this cut-off, the high-grade part of the Escondida represents reserves of 289,000 tonnes of milling ore
at an average drill-indicated grade of 10.54 g/t Au as of December 31, 2008.
