en.Wedoany.com Reported - iTech Minerals (ASX: ITM) has confirmed that portable X-ray fluorescence (pXRF) can serve as a rapid exploration tool for preliminary target delineation at the Reynolds Range Project in the Northern Territory.

The company collected 182 soil samples from the Sabre and Falchion exploration areas, with analysis results showing peak gold content of 12.1 g/t and peak antimony content of 9.1%.

Laboratory data indicate that 48 samples exceeded 0.1 g/t gold, including nine samples exceeding 1 g/t; additionally, 21 samples had antimony content exceeding 0.1%.

Field portable XRF results showed strong correlation with laboratory analysis: arsenic correlation coefficient ρ=0.91, antimony ρ=0.87, and lead ρ=0.81, confirming the reliability of this technique in preliminary target delineation.

Arsenic is the most effective indicator element for gold mineralization, with a correlation coefficient of ρ=0.83 between pXRF arsenic and laboratory gold content. Antimony showed moderate to strong correlation with gold (ρ=0.72), supporting the consistency of the gold-antimony-arsenic epithermal mineralization system.

Managing Director Mike Schwarz stated: "These results have changed our exploration approach at the Reynolds Range. This process demonstrates that pXRF soil geochemistry can provide reliable real-time vectors for gold-antimony mineralization in the field at a fraction of the cost and turnaround time of a purely laboratory-based program."

The soil sampling program identified a new mineralization zone at Falchion, with strike length extending to over 180 meters.

The anomaly includes the highest antimony result in the program—sample FS26070 with antimony content of 9.1%, along with strongly anomalous arsenic at 1011 ppm and gold content up to 314 ppb.

Mike Schwarz added: "The recently completed drone magnetic survey identified a 13-kilometer-long favorable structure, in addition to the broader 42-kilometer Stafford Gold Trend. We now have a tool to rapidly and effectively screen this vast search space."

The company plans to systematically conduct pXRF-supported soil geochemical surveys along priority targets within the Stafford Gold Trend, utilizing real-time pXRF arsenic data (supplemented by antimony and lead) for field anomaly delineation.

Drilling is scheduled to resume at the Reynolds Range on July 20, 2026, with first-phase drilling results expected to be released within the next two to three weeks.

iTech Minerals is an Australian exploration company advancing critical mineral projects, including the Eyre Peninsula Graphite Project in South Australia and gold-antimony exploration at the Reynolds Range Project in the Northern Territory.
