Highly Prospective Asmara Mineral Belt
East Africa Metals’ Harvest Project is 600 kilometres north of Ethiopia’s capital of Addis Ababa. It’s located in the highly prospective Asmara Mineral Belt in the southern part of the Arabian Nubian Shield (ANS). The Debarwa and Emba Derho volcanogenic massive sulphide (VMS) discoveries in Eritrea and SE of the Bisha deposit are 90 to 140 kilometres southwest. Bisha is now a producing gold-copper-zinc-silver mine with over 25 million tonnes at 1% copper and 0.7 grams per tonne gold of ore in reserves. Vein-related gold deposits are also typical of the ANS, including the giant >13 million ounce Sukari deposit in Egypt, the one million ounce gold discovery at Koka-Zara in central Eritrea and the 140,000 ounce per year gold producer at Lega Dembi in southern Ethiopia.
East Africa Metals acquired its interest in the Harvest Project through its acquisition of Tigray Resources in 2014. Tigray acquired a 70% interest in the project in 2011 through a joint venture with Ezana Mining Development, a private Ethiopian company. Harvest comprises three contiguous exploration concessions covering approximately 86 km2 , including Terakimti, Igub, and Hamlo (as at January 10, 2017). EAM, through its Ethiopian subsidiary company Harvest Mining PLC, has received a mining licence for the Terakimti Gold Heap Leach Project.
Multiple Trends of Copper-Gold-Silver-Zinc
The Harvest Project contains multiple trends of copper-gold-silver-zinc rich VMS systems and numerous artisanal bedrock gold workings on its three exploration licences. Until recently, the ground has not been subject to modern exploration. Exploration by Tigray in 2011-2013 has included drilling 84 diamond drill holes testing four prospects for a total of 17,765 metres, a heli-borne VTEM, magnetic and radiometric survey, ground gravity and electromagnetic (EM) surveys, over 90,000 surface soil, stream and rock chip samples, and regional to detailed geological mapping. State of the art technologies, including a Niton handheld XRF unit used for real-time base metal assay of drill core and surface geochemical samples, has allowed exploration to advance at a rapid rate.
Terakimti – Significant Results from Over 70 Drill Holes
The most advanced prospect on the Harvest Project is Terakimti, where over 70 diamond drill holes have been completed, with peak results of 73.80 metres of 3.80% copper, 1.30 grams per tonne gold and 14 grams per tonne silver, including 36.45 metres of 6.01% copper, 1.69 grams per tonne gold, 19 grams per tonne silver and 1.31% zinc in hole TD004. Significant base and precious metal mineralization has been intersected in the majority of drill holes completed. An initial 43-101 compliant mineral resource estimate was announced in January 2014 (details are provided below), and an updated oxide mineral resource estimate was announced on October 27, 2015. On August 11, 2016, EAM filed a mine permit application for the Terakimti oxide with the Ministry of Mines, Petroleum, and Natural Gas (MoMPNG), as well as applying for additional rights to related exploration targets on the Harvest ground. On December 6, 2017, the mine permit for the Terakimti Oxide Gold Project was granted.
Mayshehagne – Initial Drill Results Positive
Drilling at Mayshehagne, approximately 3.3 kilometres south of Terakimti, has intersected 20.70 metres of 4.97% copper, 1.10 grams per tonne gold, 31 grams per tonne silver and 8.20% zinc from 24.00 metres, including 12.80 metres of 7.72% copper, 1.70 grams per tonne gold, 50 grams per tonne silver and 12.70% zinc (hole HD002).
VTEM09 – Initial Drill Results Positive
A single drill hole at VTEM09, approximately 5 kilometres ENE and along strike of Terakimti, has intersected 10.69 metres of 3.47% copper, 4.20 grams per tonne gold, 91 grams per tonne silver, and 3.69% zinc from 19.81 metres, including 3.06 metres of 5.75% copper, 8.00 grams per tonne gold, 107 grams per tonne silver, and 0.70% zinc (hole TVD001).
