Barrian Mining Corp. (Barrian) has announced drill target selections for the upcoming 1800 m (5500 ft) reverse circulation (RC) drilling programme at the Bolo Gold property. The programme is designed to expand the footprint of drill-defined gold mineralisation of the mine fault trend, both along strike and at depth. Planned South Mine Fault (SMF) Zone step-out drilling will extend to the north and south of previous drill intercepts that graded 3.24 grams per tonne (g/t) gold over 30.5 m within a broader zone of mineralisation averaging 1.28 g/t gold over 133 m in drill hole BL-38, and 1.1 g/t gold over 90 m including 40.9 m of 2.05 g/t gold* from surface in drill hole BL-39. Drilling will also test a new discovery target, identified by the recently completed induced-polarization (IP) and resistivity geophysical survey.
Kris Raffle, P.Geo., Director and QP stated, "The 2019 drilling programme has the potential to expand the historically drilled footprint of SMF Zone mineralisation. We eagerly anticipate commencement of the 2019 Bolo drill programme, which is designed to build on favourable results from previous drill campaigns by incorporating the recently acquired IP/resistivity geophysical survey results. The newly identified geophysical anomaly west of the SMF Zone is particularly intriguing given its potential to represent a new discovery sub-parallel to the main Mine Fault trend".
The SMF Zone forms part of a +1.1 km combined gold and silver in RC drill hole and conductive geophysical anomaly coincident with the Mine Fault trend. North of the SMF Zone, geophysical results indicate that previous drill holes often failed to adequately test the Mine Fault conductive anomaly. The planned step-out drilling at SMF targeting the conductive anomaly has the potential to add up to 200 m of mineralised strike length, with the potential for additional expansion during subsequent programmes. The geophysical results also suggest significant vertical continuity of conductive anomalies at the SMF Zone ranging from between 250 - 400 m depth, the limit of the geophysical inversion. The planned drilling, in part, targets the down-dip extension of previously defined mineralisation coincident with these geophysical anomalies. The geologic and geophysical evidence suggests that the previously drilled gold and silver zones at Bolo could be inter-connected along Mine Fault trend structure.
New discovery drilling is planned for an untested, + 500 m linear conductive anomaly located approximately 150 -200 metres west of the SMF Zone. The anomaly is near surface, of similar amplitude to the Mine Fault anomaly, and ranges from 80 - 200 m wide and 100 - 150 m in vertical extent. It is sub-parallel to the Mine Fault Trend and may be part of the same fault system that hosts a distinct silver and gold mineralised zone at the Uncle Sam prospect.
