American Tungsten & Antimony (ASX:AT4) said surface sampling at its Tennessee Mountain Tungsten Project in Nevada, US, has defined a broad tungsten anomaly across the project area and confirmed high-grade tungsten mineralization at the historic Garnet Mine, according to a Tuesday Australian bourse filing.
The company said channel samples from the Garnet Mine returned 4,713 parts per million tungsten, or 0.6% tungsten trioxide, over one meter and 4,191 parts per million tungsten, or 0.5% tungsten trioxide, over 2 meters from outcropping skarn.
A peak rock chip result of 20,693 parts per million molybdenum, or 2.1% molybdenum, was also returned at the Garnet Mine, with three further samples grading between 2,055 and 4,352 parts per million molybdenum, consistent with a fertile, intrusion-related tungsten-molybdenum skarn system, the filing added.
A maiden 29-hole, roughly 3,000-meter drill program has been designed to test the depth and lateral extensions of the skarn system at the Garnet Mine, it added.
