Tembo Gold (TSXV:TEM) announced the results from its preliminary metallurgical testing conducted on 32 samples during an artisanal mining sampling program. The company’s Tembo project in the Lake Victoria goldfield in Tanzania is expected to yield 90-95% gold.
Tembo Gold (TSXV:TEM) announced the results from its preliminary metallurgical testing conducted on 32 samples during an artisanal mining sampling program. The company’s Tembo project in the Lake Victoria goldfield in Tanzania is expected to yield 90-95% gold.
As quoted in the press release:
The study consisted of the following:
- Gold (Au) and sulfur (S) assays were conducted on each sample. Based on the gold results, the samples were grouped into three composite samples: low grade 0 to 3g/t Au, medium grade 3 to 6g/t Au, and high grade 6 to 60g/t Au.
- Test work to determine the amenability of the mineralized material to gravity recovery.
- Grading analysis to determine the gold distribution across the size fractions.
- Heavy Liquid Separation (HLS) to determine the amount of free gold or gold that would respond to gravity recovery.
- Chemical analysis to determine the compositions of ore and metallurgical test products.
- General mineralogical characterization of the ore by XRD and QEMSCAN.
- Identification and quantification of gold minerals, including native gold, gold telluride etc. in the gravity concentrate.
- Exposure and mineral association analysis of particulate gold grains in the gravity concentrate.
- Grain size distribution analysis of gold grains in the gravity concentrate.
- Test work to determine gold recovery by direct cyanidation.
- Diagnostic leach test of gravity tails in order to determine the gold deportment in gravity tails.
The average grades of the three composites, low grade, medium grade and high grade were 1.83g/t, 6.22g/t, and 18.26g/t gold and 0.7g/t, 1.5g/t and 1.8g/t for silver respectively.
President & CEO of Tembo Gold, David Scott, stated:
These preliminary gold deportment study and metallurgical response results on near surface gold mineralization being exploited by artisanal miners suggest that gravity recovery and direct cyanidation of shallow gold mineralization at the Tembo project will return high recovery. Tembo will continue to test artisanal ore and once sufficient gold intersections have been achieved from the current drill programs, conduct gold deportment test work on in situ mineralization encountered.
