The 100% Erdene-owned Altan Arrow gold-silver prospect is situated on the Bayan Khundii license, 3.5 kilometres north of the Bayan Khundii project, at the intersection of proposed major deep-seated structures.
Initial exploration by Erdene in 2013 confirmed the presence of high-grade gold and silver within epithermal quartz veins and breccias, and the potential for broader mineralized zones. Erdene geologists subsequently identified an approximately 1 square-kilometre area of anomalous gold-silver mineralization in quartz veins that returned up to 57 g/t gold in hand samples and 1 metre of 31.4 g/t gold and 6 metres of 4.5 g/t gold in initial trenching.
In 2017, the Company completed structural mapping south of the main northeast-trending structure that hosts the originally targeted epithermal veins and breccias. The Company identified an east-west trending cross-structure with associated gold-in-soil anomalism. Follow-up surface sampling and geological mapping of the soil anomaly in Q3 2017 resulted in the discovery of surface quartz vein rubble that returned 27 g/t gold.
The Company’s Q4 2017 drill program included two holes to test this east-west structure. Hole AAD-11 intersected multiple anomalous gold zones spread over the 100 metre length of the hole (45 degree angle), including a shallow gold-bearing epithermal vein at 11 metres vertical depth that returned 1 metre of 39 g/t gold and 8 g/t silver.
Prior to the Q4 2017 drill program, the only hole completed along this east-west structure was AAD-03, approximately 300 metres east of AAD-11. Hole AAD-03 intersected 2 metres of 23.5 g/t gold at 50 metres vertical depth. Hole AAD-12, completed in Q4 2017, was a 150 metre deep hole drilled to test the continuity of that intersection at depth, and returned 2 metres of 70.1 g/t gold and a second intersection of 2 metres of 1.3 g/t gold within 100 metres of surface.
