Thomson Resources announced its JORC 2012 Mineral Resource Estimate (MRE) for the Webbs high-grade silver base metal deposit, prepared by AMC Consultants Pty Ltd. (AMC). This is the first MRE for Webbs reported in accordance with the 2012 edition of the JORC code and delivers total Indicated and Inferred mineral resource of 2.2 Mt at 205 g/t AgEq for a total 14.2 Moz AgEq at a 30 g/t Ag cutoff, comprising 9.7 Moz Ag, 23.9 kt Zn, 11.9 kt Pb, and 3.3 kt Cu. The Webbs MRE is the fifth and final resource update for Thomson's Tablelands Group of 100% owned deposits representing a full restatement of the Webbs, Conrad, Silver Spur, Twin Hills and Mt Gunyan resources within a 10-month period.

Combined, these deposits contain total Indicated and Inferred resources of 16.8 Mt at 101 g/t AgEq for a total of 54.4 Moz AgEq. Metal recoveries used in the calculation of the AgEq grades for Thomson's MRE were based on previous metallurgical test work undertaken by SVL in 20136. These tests assumed processing via a standalone, conventional processing pathway of grinding to 212 micron, and standard flotation and cleaner process to produce a silver and base metal concentrate.

This test work delivered favorable recoveries and metal grades, however it was noted in the metallurgical report that the concentrate also contained elevated levels of arsenic. The company is working with CORE on arsenic mitigation strategies for the Webbs mineralisation in the context of the company's Hub and Spoke Process Pathway study, that include concentrate blending and hydrometallurgical processing options to address this issue. The new Webbs MRE has been independently prepared for Thompson Resources Ltd. by AMC Consultants Pty Ltd. (AMC) and reported in accordance with the 2012 JORC Code for reporting of Mineral Resources.

The Webbs MRE at a 30 g/t Ag cut off delivered an Indicated and Inferred Mineral Resource of 2.2 Mt at 140 g/t Ag, 0.15% Cu, 0.55% Pb and 1.10% Zn, containing 9.7 Moz Ag, 3.3 kt Cu, 11.9 Kt Pb and 23.9 kt of Zn. On a AgEq basis, the combined Webbs resource totals 14.2 Moz AgEq in 2.2 Mt at an average grade of 205 g/t AgEq.
