WATCH: iTech Minerals’ (ASX: ITM) Managing Director Mike Schwarz takes the latest episode of Ask iTech on the road to show investors the importance of the game-changing soil sampling results at the Falchion Prospect. (4 min)
HIGHLIGHTS
- Soil sampling returns outstanding peak values of 12.1g/t Au (SS26002, Sabre) and 9.1% Sb (FS26070, Falchion) in laboratory assays
- 48 of 182 samples returned >0.1 g/t Au, including 9 samples >1 g/t Au; 21 samples returned >0.1% Sb in laboratory assays
- Field-portable XRF (pXRF) results correlate strongly with laboratory assays for As (ρ = 0.91), Sb (ρ = 0.87) and Pb (ρ = 0.81), validating pXRF as a rapid, low-cost first-pass targeting tool
- Arsenic is confirmed as the most effective pathfinder for gold -pXRF. As correlates with laboratory Au at ρ = 0.83, almost matching laboratory As (ρ = 0.86)
- Antimony shows a moderate-to-strong correlation with gold (laboratory ρ = 0.72), consistent with a coherent Au-Sb-As epizonal mineral system
- Soils define new zone of mineralisation at Falchion, extending strike to over 180m
- Results support the roll-out of systematic pXRF supported soil geochemistry across the 13km of structures identified in the recently flown drone magnetics
- Drilling results from first phase of drilling due in next 2-3 weeks
These results are a gamechanger for how we explore at Reynolds Range. The process has demonstrated that pXRF soil geochemistry gives us reliable, real-time vectors to gold–antimony mineralisation in the field, at a fraction of the cost and turnaround time of laboratory-only programs. The survey has already identified a new zone of mineralisation at Falchion.
With 13 kilometres of prospective structures identified in the recently flown drone magnetics, and the broader 42-kilometre Stafford Gold Trend beyond that, we now have a tool that lets us screen this enormous search space quickly and effectively - defining and infilling anomalies within a single field campaign and ensuring our drilling is targeting the highest-quality gold–antimony targets.
