- 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.
Ore is free milling
and is treated on-site by conventional crush-grind-carbon in pulp processing to produce gold-silver dore.
Willow Creek gold is reported to be free milling
with greater than 80 percent recovery by gravity alone and recoveries up to 95 percent reported from gravity and flotation processing.
An additional benefit is contamination free milling
that results from the lack of component wear.
At Tulkubash (including mostly free milling
mineralization), resources are believed to be increased by 56% to 501K ounces from 321K ounces, with the sulphide (refractory) section of the resource also increasing by 25% to 5.09 million ounces.
Consultant John Wells, who oversaw the test work, said the Goliath gold samples gave "excellent" recovery which is "indicative of free milling
, clean, non-refractory ore." He said the results can support the development of a concentrator design, capital and operating costs at a scoping or pre-feasibility study stage.
In the area of gold, extensive experience has been gained in all aspects of gold metallurgy, from conceptual studies and pilot scale testwork through to process design and plant commissioning of both 'free milling
' and complex/refractory operations.
