East Africa Metal’s 70%-owned Harvest polymetallic VMS exploration project covers about 116 km2 in the Tigray region of Ethiopia, 600 km north‐northwest of the capital city of Addis Ababa.
The 20m x 20m spaced resource drill-out specifically targeted the gold and gold-silver oxide portion of the deposit and totalled 6 190m of drilling in 125 holes. The assay results have now been received for all drill holes in the programme. Preliminary results have also been received for four exploration RC drill holes at the Lihamat and Adi Asgedom gold prospects.
Highlights from resource drilling of the oxide component of the Terakimti VMS deposit include:
- 20m grading at 8.92 g/t of gold and 24.3 g/t silver, from a 24m drill depth (TRC085A);
- 14m grading at 5.29 g/t of gold and 169.7 g/t of silver, from a 33.0m drill depth (TRC095); and;
- 0m grading at 7.34 g/t of gold and 1.3 g/t of silver, from surface (TRC109).
Highlights from first pass exploration drill targeting at the Lihamat gold prospect, approximately 2.9km NE of Terakimti, include:
- 0m grading at 111.6 g/t of gold, from a 24m drill depth, and 4.0m grading at 4.45 g/t of gold from a 56m drill depth (LRC003).
The 20m x 20m spaced RC oxide drill program has been completed, and revision of the oxide portion of the initial independent gold/silver-base metal resource is in progress. The drilling has continued to highlight well developed zones of gold mineralisation along the length of the deposit. More detailed metallurgical testwork will follow the revision of the oxide resource.
Lihamat and Adi Asgedom
A total of 354 m of exploration RC drilling has been completed in three holes at the Lihamat gold prospect, approximately 2.9 km NE of Terakimti, and one hole was completed at the nearby Adi Asgedom prospect.
The drill holes tested mineralisation below artisanal workings which have exploited high-grade gold-bearing quartz veins.
All drill holes were composite sampled, where four individual one metre samples were composited together into one sample for assay. These will be individually sampled (riffle split) for all composite samples containing gold grade of greater than 0.3 g/t.
LRC003 at Lihamat intersected 4m grading at 111.6 g/t of gold, from a 24m drill depth, and 4m grading at 4.45 g/t of gold from a 56m drill depth. Additional splits (of individual 1m samples) will be conducted on the mineralised zones. The mineralisation is interpreted to be related to zones of quartz veining with disseminated pyrite within intense silica alteration of a quartz porphyry intrusion.
East Africa Metals intends to commence a diamond drill program in the last quarter of 2015, to conduct infill and extension drilling of the gold/copper resources at Mato Bula and Da Tambuk.
The company will continue to advance both the Harvest and Adyabo projects, through detailed metallurgical test work and engineering studies at Terakimti, following revision of the current resource, and upgrading of the resource at Adyabo through infill and extensional diamond drilling.
