Yasnoye is a prospect within the large Afanasevskoye license, situated c.30km west from the Albyn RIP plant. It is a former small scale underground mine, which in the 1950s mined high grade, shallow dipping, narrow quartz veins (up to 32.6g/t and 0.12 to 3.0m thick).
A geochemical survey completed by Petropavlovsk confirmed a possible 3km mineralised extension of the deposit. Five trenches were developed to explore this structure beyond the area mined in the past. Initial assay results from one of the trenches confirmed the presence of a subparallel, shallow dipping gold bearing structure, with intersections of 12.2m at 4.72g/t, 6.0m at 3.09g/t and 6.0m at 2.37g/t.
These results confirm that gold is not only associated with the quartz veins but also found in the wall rock - 2016 trenching identified grades up to 2.0-3.0g/t here. As historical exploration only targeted the visually identifiable quartz veins, the lower grade ‘halo’ gold mineralisation was not adequately sampled or explored. Therefore there remains a possibility that Yasnoye could contain larger scale, low grade mineralisation that may be suitable for open pit extraction. The 2017 exploration programme budgets for further focused exploration works to be carried out to verify this concept.
