Orefinders Resources Inc. (TSXV:ORX) commenced a preliminary metallurgical scoping testwork program on selected stockpile mineralization at the Mirado project. Three separate stockpiles contain a current NI-43-101 compliant mineral resource of 20,742 tonnes with an average grade of 4.41 grams per tonne gold.
As quoted in the press release:
Metallurgical Test Program
Four 30 kilogram samples were submitted to SGS Minerals Services in Lakefield, Ontario. Metallurgical testwork currently underway will include the following studies:
- Bond work index determination
- Gold assaying by pulp and metallic for low, medium and high grade material
- Whole rock analysis, ICP multi-element, total sulphur and arsenic analysis
- Specific gravity determination
- Bond ball mill grindability test using the standard 100 mesh closing screen
- Gold recovery evaluated in standard bottle roll cyanidation tests
- Environmental characterization of leach residues
Orefinders Resources President and CEO, Bill Yeomans, said:
It is anticipated that metallurgical scoping test work on material stockpiled from the Mirado gold deposit will be completed before year end. The information gained from this study will assist us in determining how the stockpiled material at Mirado should be processed in order to maximize gold recovery. Using a 2 gpt Au cut-off, the average grade of 20,742 tonnes of stockpiled material is 4.41 gpt Au, which is sufficiently high enough for Orefinders to consider trucking this material should a compatible custom mill be identified. If successful, the Mirado stockpile has the potential to provide Orefinders with a significant non-dilutive financing to the company.
