Thomson Resources Ltd. announced restated, polymetallic Mineral Resource Estimates (MRE's) in accordance with the "Australasian Code for Reporting of Mineral Resources and Ore Reserves" (the JORC Code as prepared by the Joint Ore Reserve Committee of the AusIMM, AIG and MCA and updated in December 2012) (2012 JORC Code) for the Strauss Kylo (including Kylo West) deposits, prepared initially by Mining Plus Pty Ltd. in 2017 for White Rock Minerals Ltd. WRM MRE's reported in WRM ASX announcements only contained gold and silver. As such, this is the first MRE for Strauss and Kylo which includes zinc and copper as well as gold and silver. The Thomson Strauss and Kylo polymetallic MRE's deliver an Indicated and Inferred Mineral Resource of 6.00 Mt at 1.17 g/t Au, 1.59 g/t Ag, 0.33% Zn, 0.06% Cu, for a contained 225 Koz Au, 306 Koz Ag, 19.8 kt Zn and 3.5 Kt Cu.

Metallurgical Recoveries and Test Work: As part of the WRM 2017 pre-feasibility study, WRM engaged ALS Metallurgy to undertake initial metallurgical test work on the Strauss, Kylo, Lady Hampden and White Rock deposits. The test work considered various processing routes including flotation to a concentrate for sale, flotation to a concentrate for subsequent cyanide leaching, and a whole ore conventional cyanide leach by CIL process. On the basis of this test work, the 2020 WRM PFS update assumed 83% recovery of gold, based on a conventional CIL plant for recovery of gold only .

This approach did not allow for recovery of the zinc in the Strauss and Kylo deposits. New England Fold Belt Hub and Spoke Centralised Processing Concept: The restatement of the Strauss and Kylo MRE's is a first step in reporting the Mt Carrington Project resources under the 2012 JORC Code. Mt Carrington hosts other predominantly silver +/- base metal bearing deposits where White Rock have previously announced significant silver (gold) MRE's including, Lady Hampden: silver -­ gold deposit, Silver King: silver -­ lead deposit, White Rock: silver-zinc deposits, Guy Bell: gold-zinc-copper deposit.

Thomson will now focus on restating the MRE's for these Mt Carrington deposits folding the contained silver-gold base metal into the larger resource base for the NEFBHS concept where Thomson has a stated objective of 100 Moz of AgEq aggregate resource base to potentially catalyse the central processing strategy. Thomson has recently reported updated MRE's for its 100% owned Tablelands projects, contain an aggregate silver-base metal resource base of 16.8 Mt at 101 g/t AgEq for a total of 54.4 Moz AgEq. In the context of Thomson's NEFBHS 100 Moz AgEq aggregate resource base objective, the Tablelands MRE's and the restated Strauss and Kylo polymetallic MRE's on an 100% basis (Thomson is earning up to a 70% project interest in Mt Carrington1) totals 22.8 Mt at 119 g/t AgEq for a total resource base of 87.1 Moz of AgEq, including a higher-grade subset of 12.2 Mt at 181 gt/AgEq or 70.9 Moz of AgEq .

The previously announce MRE's for the Mt Carrington Lady Hampden, Silver King and White Rock deposits11demonstrate sufficient contained silver-gold-base metals for Thomson to potentially achieve the aggregate 100 Moz AgEq objective for the combined NEFBHS concept. The Tablelands and Mt Carrington deposits combined now constitute Thomson's NEFBHS Projects, are located within a potential trucking radius and have geo-metallurgical compatibilities which may be amenable to similar mineral processing techniques. Thomson, together with CORE Resources, is well advanced on a metallurgical Process Study to investigate strategies for a centralised processing facility to process mineralisation from the NEFBHS deposits.
