Khao Soon Tungsten Project (PAM 100%)

Khao Soon Tungsten Project

Project Summary

Exploration Target (JORC 2012, Drill Supported) defined, 15 – 29Mt @ 0.2% to 0.4% WO3

  • Historic Khao Soon Tungsten Mine estimated average grades of 2-4% WO3
  • Over 10 individual prospects, combined prospective strike length ~10km
  • Mineralised zones from surface with peer group leading drill intersections
  • Strong drilling results broadly support Exploration Target model

Project Overview

Khao Soon mine production to 1979:

  • Historic production grades est. at 2-4% WO3
  • In 1974 USGS personnel reported that the high grade material
  • being mined has an estimated wolframite content of 20%

To date 41 diamond core holes for a total of 3,514m

  • Drilling highly successful, discovering near surface intersections containing good tungsten grades over considerable widths.
  • Drill supported Exploration Target (ET) 15-29Mt @ 0.2%-0.4% WO3 defined in accordance with the JORC Code (2012)
  • ET generated with information from drill holes KSDD001-022
  • ET model supported by recent drilling (KSDD023-041, 1,602m)

Hard rock tungsten (wolframite) mineralisation generally hosted in high grade breccia

Extensive oxide hosted tungsten mineralisation:

  • Tungsten in thick profiles at/near surface
  • Likely vectors to underlying hard rock WO3 mineralization
  • Best intersections include:
    • KSDD001 – 51.5m @ 0.50% WO3 from 0m, incl. 12.8m @ 1.07% WO3 from 14.8m
    • KSDD021 – 14.55m @ 0.47% WO3 from 0m, incl. 7.3m @ 0.62% WO3 from 0m
    • KSDD024: 13.1m @ 0.51% WO3 from surface, incl. 4.6m @ 0.97% WO3 from 8.5m
