Riversgold Ltd (ASX:RGL) has found high-grade gold in rock chip samples grading up to 90 g/t gold at its Gemuk Mountain Project in Alaska, 15 kilometres northeast of its Luna-Quicksilver (LQ) prospect.
The company has also outlined a potential second highly-anomalous target zone with soil results up to 1.27 g/t.
Gemuk is at the north-eastern end of the North Fork fault, a regional structure which hosts outcropping high-grade gold mineralisation at the LQ prospect.
Riversgold managing director Allan Kelly said the results at Gemuk confirmed the importance of the North Fork fault and the Pluton fault as a focus for high-grade gold mineralisation.
“We now have at tenure over four high-grade gold occurrences within the North Fork fault over at least 32 kilometres of strike.
“Anyone of these prospects has the potential to develop into a large intrusion-related gold deposit and we look forward to continuing to outline the opportunities in the next field season.”
The company staked several state-owned mining claims over Gemuk in early 2018 following up a number of historical high-grade rock chip results grading up to 100 g/t gold.
These results were from within the Pluton fault, a structure parallel to the North Fork fault.
Recently completed rock chip, ridge and spur soil sampling over Gemuk has extended the area of mineralisation along the Pluton fault to around 2 kilometres while soil sampling has outlined a potential second zone of mineralisation south of Pluton.
Further sampling, along with detailed helimagnetic surveys, is planned for the 2019 field season.
