Orefinders Commences Metallurgical Scoping Testwork on Mirado Stockpile
Orefinders Resources Inc. (TSX.V: ORX) reports that a preliminary metallurgical scoping testwork program has commenced on selected stockpile mineralization at Orefinders 100% owned Mirado project, where 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 (gpt Au).
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
Bill Yeomans, P. Geo., President and CEO, states that, “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.”
The technical information contained in this news release has been reviewed and approved by Kevin Piepgrass, P.Geo, Vice-President Exploration for Orefinders, who is a Qualified Person as defined in “National Instrument 43-101, Standards of Disclosure for Mineral Projects.”
