Matsa Resources Limited
Matsa Resources Limited ("Matsa" or "the Company" ASX: MAT) is pleased to report highly positive results from its recently completed Mining Study for the proposed Stage 2 mining operations at the Company's Fortitude gold deposit within the 100%-owned Lake Carey Gold Project in the Eastern Goldfields of Western Australia.
The study shows that the Stage 2 mining is attractive with a potential cash surplus of A$21.8M over a period of 22 months with a modest capital investment of only A$6.6M. A sensitivity analysis indicates that the project is robust with potential for improvement to the financial model as new optimisations come to hand. Finalisation of discussions with key parties and completion of the tender process may deliver further improvements.
Metallurgical test work indicates that Fortitude ore is amenable for treatment at any of the nearby processing facilities, and will deliver very good-to-excellent gold recoveries with no deleterious elements. Matsa is currently assessing processing options for the treatment of ore from Fortitude, and is in discussions with AngloGold Ashanti Australia Limited (AGAA), which is currently treating gold ore from Matsa's nearby Red October underground gold mine under a five-year Ore Purchase Agreement between Matsa and AGAA.
Matsa Executive Chairman Mr Paul Poli said:
"Based on the positive outcomes of the Stage 2 Mining Study, we will now immediately move ahead with plans to tender for the mining contract, finalise ore purchase and treatment options and secure project financing to facilitate the commencement of the Stage 2 mining operations at Fortitude. In conjunction with our ongoing mining operations at the Red October underground gold mine, the proposed Stage 2 mining of Fortitude has the potential to deliver significant cash flows for the Company and value for our shareholders."
Summary Details of the Stage 2 Mining Study are included in this announcement
Fortitude Stage 2 Mining Study Summary

- Assumed gold price of A$2,150
- Production 1.029M t @ 1.8g/t (58,080 oz contained) with 54,400 recovered ounces of gold
- Total movement of 5.85M bcm's
- Waste to ore ratio 14.4
- Operating cash cost per ounce A$1,628

Importantly, all regulatory and statutory approvals are already in place which permits immediate commencement of mining activities. Tenders for the mining are to be called as well as finalisation of ore purchase/treatment options, which are well advanced.
Upon completion of drilling in 2016 and subsequent modelling and depletion of the resource due to the Stage 1 Trial Mining, the Indicated Mineral Resource at Fortitude is 2,945,000t @ 1.8g/t (170,400 oz). The total Indicated and Inferred Mineral Resource estimate for Fortitude now stands at 5,449,000
- 2.0g/t (342,600 oz). Cut-Offgrade
The Mineral Resource has been reported at a cut-off grade of 1 g/t. This is reasonable considering the style of the deposit, the proximity to process facilities and to the selection of open cut mining equipment and methods used.
Fortitude Project Background
Matsa's Fortitude deposit is located in the southern portion of the prolific Laverton Tectonic Zone (LTZ). The deposit is located just 25km south of AngloGold Ashanti Australia Ltd's Sunrise Dam Gold Mine (10Moz), 60km south of Gold Fields Ltd's Granny Smith Gold Mine (11.6Moz) and 12 km southeast of Matsa's Red October Gold Mine (0.342Moz).
The Fortitude deposit was discovered in 1998 during regional exploration by Aurora Gold Ltd. The project was acquired by Midas Resources Ltd in 2002 who divested it to Fortitude Gold Pty Ltd in 2014.

The bulk of historic work was completed by Aurora and Midas who drilled 523 RC, AC and diamond drill holes into the deposit area. Also completed was a number of prefeasibility and feasibility studies into a heap-leach/dump leach operation and the viability of constructing a 600tpa CIL treatment plant.
Matsa purchased the Fortitude project from the receivers of Fortitude Gold Pty Ltd in 2016 (refer to the ASX announcement of 21st July 2016). Matsa subsequently completed an audit of the Resource figures and the Mineral Resource estimate was confirmed as a JORC 2012 compliant Mineral Resource (refer to the ASX announcement of 1st September 2016). Matsa subsequently commenced a diamond drilling program to provide drill core for metallurgical, geotechnical and resource definition purposes (refer to the ASX announcements of 15th November 2016 and 14th December 2016).
Matsa has also previously completed the required heritage, hydrogeological, flora, fauna, community consultation and geotechnical studies which were included in the mining proposal at the trial mining stage which was approved by DMIR's in 2017. Matsa successfully conducted the Stage 1 trial mine during the 2017/2018 years which was completed in May 2018 (refer to the ASX announcement of 19th June 2018).
Study Scope
A mining study at Fortitude gold deposit commenced in July 2016 to evaluate the technical and financial viability of mining the Fortitude deposit. Trial mining was successfully undertaken in 2017/2018 with ore from the trial mine taken to AGAA's Sunrise Dam Gold Mine processing plant and this current study evaluates the financial and technical viability of mining the remainder and larger part of the gold deposit (Stage 2) using a conventional open pit operation.
The Ore Reserve Estimate data, economic evaluation and Stage 2 Mining Study has been comprehensively reviewed by Matsa senior management.
The study is classified as a Scoping study with a confidence level of +/-20%.
Geology and Mineralisation
Gold mineralisation at Fortitude is associated with the Fortitude Shear Zone, a north-northwest striking shear which extends the length of the project. Ductile shearing and mineralisation is focussed within an intermediate volcanic unit adjacent to relatively undeformed mafic rocks.
Gold mineralisation forms continuous steeply dipping quartz lodes along the Fortitude Shear and is accompanied by pervasive wallrock siderite-sericite-silica alteration and vein quartz (locally +/- carbonate) with pyrite +/- arsenopyrite in the deeper sulphide zones.
Vein intensity, siderite/sericite alteration and sulphide minerals are indicative of better Au grade.
Mineral Resource Update
Matsa has updated the Mineral Resource estimate to allow for depletion due to the Stage 1 trial mining.
Total Indicated and Inferred Mineral Resources for the Fortitude gold project now stands at 5,449,000 @ 2.0g/t for 342,600 oz (Refer Table 1).
