Crater Gold Mining Limited announced further results from the ongoing metallurgical test work on graphite mineralisation from the Golden Gate Graphite Project at Croydon in North Queensland. ALS Metallurgy Perth, have undertaken a flotation test on an 850 micron sample (composite 2) with an encouraging result obtained. A total of 89.4% of the graphite feed has reported to a rougher concentrate, with the concentrate being found to have a graphite grade of 76.9%.

At this stage, no attempt has been made to purify the graphite product as previous caustic baking of a lower grade graphite rougher concentrate has provided an excellent graphite purity of 98.9%. Testing of additional grain sizes will now be undertaken to determine the optimum grain size for on-going test work. An optimised flotation rougher concentrate of that selected grain size will then be prepared and screened to determine the graphite flake size distribution which will indicate its potential market value.

Based on previous petrographic examination, it is anticipated that the mix of graphite sizes possibly present may include fine-flake, through to large, jumbo and perhaps super jumbo flake sizes. If favourable results were obtained, test work would then be undertaken to establish if high value-added micronisation and/or spheronisation graphite production might be economically achievable. As previously announced to the ASX (High Graphite Recovery and Purity Obtained from Metallurgical Test Work, Golden Gate Graphite Project, 24 July 2019), the Company drilled two diamond core holes in the thick graphite mineralisation in the previously identified Golden Gate Graphite Project area in EPM 18616.

The purpose of this was to obtain fresh graphite mineralisation for metallurgical testing and to verify the previously reported drill intersections at the sites selected. The results obtained were as follows; Hole GGDDH 1701 62.7m @ 6.79% GC from 29.3m (cut off 3.4% GC incl 7.0m @10.07 % graphitic carbon (cut off 9.4% GC) Hole GGDDH 1702 53.9m @ 6.79% GC from 69.1m (cut off 3.1% GC) incl 14.0m @ 8.79% graphitic carbon (cut off 6.1% GC).
