Tungsten Mining NL reported a major Mineral Resource Estimate update at the Mt Mulgine Project in the Murchison Region of Western Australia, approximately 350km north northeast of Perth. The Company owns 100% of the tungsten and molybdenum rights on a group of tenements that have been the subject of significant previous evaluation for tungsten and molybdenum. The Company also has the rights to all by-products from the mining of tungsten and molybdenum. Near surface Mineral Resources have been delineated at the Mulgine Trench and Mulgine Hill deposits, which have been the subject of ongoing evaluation by the Company. In April 2019, the Company commenced work on a Pre-Feasibility Study (PFS) for large scale mining operations at the Mt Mulgine Project. It is anticipated that one of the outcomes of the PFS will be that a significant portion of the Mulgine Trench Mineral Resource will be classified as Indicated, supporting the declaration of a maiden Ore Reserve for the larger Mt Mulgine Project. In July 2019, the Company commenced resource definition drilling at Mulgine Trench with results from the first 123 reverse circulation (RC) holes received by 22 November 2019. Resource consultants, Optiro Pty Ltd. (Optiro) were engaged to update the Mulgine Trench Mineral Resource and completed this exercise in December 2019. Mulgine Trench Mineral Resource The previous Mulgine Trench Mineral Resource estimate was completed by CSA Global in November 2014 for tungsten and molybdenum within 0.10% WO3 domains. This estimate was based on drilling on 80 metre to 180 metre spaced sections with 40 metre to 80 metre spaced holes on sections. Since the June 2014 Mineral Resource estimate, the Company has drilled an additional 143 RC holes for 21,157 metres and five PQ diamond holes for 560 metres. The reported Mineral Resource is constrained within limits defined by a pit shell with an ammonium paratungstate (APT) price of US$400 per mtu revenue factor. This pit shell was used to demonstrate that there are reasonable prospects for eventual economic extraction in accordance with the 2012 editon of the JORC Code. At a 0.05% WO3 cut-off grade, this has resulted in a 189% increase in tonnes and an increase in contained metal of 97% in tungsten and 211% for molybdenum. In addition, gold and silver grades were estimated into the block model and this defined 850,000 ounces of gold and 35 million ounces of silver. Tungsten-molybdenum mineralisation at Mt Mulgine is associated with the Mulgine Granite - a high-level leucogranite forming a 2km stock that intrudes the Mulgine anticline. The granite intrudes a greenstone sequence composed of micaceous schists, amphibolite and talc-chlorite schist which were formerly metasediments, mafic and ultramafic rocks respectively. Mineralogical and metallurgical studies on the range of ore types from the Mulgine Trench deposit show scheelite well liberated at coarse sized fractions, resulting in high grades and recoveries via simple gravity techniques. Molybdenum was liberated at finer sized fractions and showed high recovery and upgrades through a flotation circuit. "Sighter" leach tests completed on two composites of low grade oxide samples resulted in a high extraction rate for gold. In addition, historical test work showed that accessory minerals gold and silver were recovered into the sulphide flotation concentrate as by-products in the process of recovering molybdenum. The deposit was sampled using diamond drilling (DD) over several campaigns from 1970 to 1981 and numerous RC drilling programs targeting gold since 2001. Earlier campaigns were conducted by Minefields Exploration NL and Australian and New Zealand Exploration Company targeting tungsten-molybdenum mineralisation. The majority of this drilling was vertical with a total of 74 NQ and BQ diamond drillholes (8,517 m DD, 1,840 m pre-collars).
