Mawson Drills 17.7 Metres at 3.7 g/t Gold and 0.7% Antimony Including 2.2 Metres @ 15.8 g/t Gold and 3.3% Antimony at Sunday Creek in Victoria, Australia

Vancouver, Canada — Mawson Gold Limited (“Mawson” or the “Company”) (TSX:MAW) (Frankfurt:MXR) (PINKSHEETS: MWSNF) is pleased to announce assay results from two further drill holes (MDDSC011-12) and multi-element data for remaining holes drilled by Mawson from the 100%-owned Sunday Creek project in the Victorian Goldfields of Australia. Holes were drilled below the historic Apollo and Gladys mine areas. The project is an epizonal-style gold prospect located 56 kilometres north of Melbourne and contained within 19,365 hectares of granted exploration tenements.

Highlights: 

  • Diamond drillhole MDDSC0012, the deepest hole and Mawson’s best drill result to date at Sunday Creek, was drilled 110 metres vertically belowthe historic Apollo mine workings and intersected thick and high-grade mineralized intervals over a combined width of 36.4 metres @ 2.4 g/t gold (“Au”) and 0.4% antimony (“Sb”) (2.8 g/t gold equivalent (“AuEQ”)) from 177 metres (without a lower cut) (Tables 1-4, Figures 1 and 2): Better intervals included (lower cut of 0.3 g/t Au cut over 2.0 metre width, with higher grades reported with a 5 g/t Au cut over 1.0 metre):
    • 13 metres @ 1.7 g/t Au and 0.14% Sb (1.9 g/t AuEQ) from 177 metres
      • including 0.8 metres @ 11.4 g/t Au and 0.9% Sb (12.3 g/t AuEQ) from 178.0 metres
    • 17.7 metres @ 3.7 g/t Au and 0.7% Sb (4.4 g/t AuEQ) from 196.0 metres
      • Including 10.4 metres @ 5.4 g/t Au and 1.0% Sb (6.4 g/t AuEQ) from 203.0 metres
        • 0.2 metres @ 37.3 g/t Au and 12.0% Sb (49.2 g/t AuEQ) from 207.0 metres and
        • 2.2 metres @ 15.8 g/t Au and 3.3% Sb (19.2 g/t AuEQ) from 209.0 metres
  • The high-grade tenor of the epizonal Sunday Creek is now becoming evident with full gold and antimony assays available for all Mawson drill holes for the first time, with the opportunity to develop similar high-grades as seen in adjacent mining operations such as Mandalay Resource’s Costerfield mine or Kirkland Lake Gold’s Fosterville mine.  Better results to date from Mawson’s drilling include:
    • 2.0 metres @ 18.6 g/t Au and 0.5% Sb (19.1 g/t AuEQ) from 74 metres in MDDSC010
    • 0.3 metres @ 82.8 g/t Au and 13.8% Sb (96.5 g/t AuEQ) from 54 metres in MDDSC002
    • 0.1 metres @ 52.6 g/t Au and 7.5% Sb (60.0 g/t AuEQ) from 124.0 metres in MDDSC005
  • Diamond drillhole MDDSC0011, the most northerly hole at the Gladys, intersected moderate thickness and grade mineralization on the margins of the Gladys structure (Tables 1-4, Figures 1 and 2) including 1.0 metres @ 3.1 g/t Au from 100.0 metres;
  • Fourteen drill holes (MDDSC001-014) for 2,487 metres have been now completed at the Sunday Creek gold project. Drilling continues;
  • A 2,500-point soil sampling program at Sunday Creek has commenced extending east-northeast from drilling areas to test the 11 kilometre trend of historic epizonal dyke-hosted mineralization within Mawson’s tenured areas.

Michael Hudson, CEO, states: “Sunday Creek is shaping up as one of the best discoveries to emerge from the new wave of gold exploration in Victoria, with this new drilling delivering our best and deepest result from the project. Impressively, we see a broad zone of mineralization (36.4 metres @ 2.4 g/t Au and 0.4% Sb) that includes multiple high grade sheeted veins including 0.2 metres @ 37.3 g/t Au and 12.0% Sb and 2.2 metres @ 15.8 g/t Au and 3.3% Sb. MDDSC012 is the first drill hole to test beneath old mine workings, and demonstrates that high-grades continue to depth. Drilling continues with the Company looking to bring in extra drill capacity. As we continue to extend the system in all directions, the chance to find further high-grade blow outs at Sunday Creek remains an exciting opportunity.”

Mawson has drilled strong gold results from multiple sheeted vein structures within a 200 metre by 150 metre area (Figure 1) with over 500 metres strike to test between historic mines, before drilling will step out to test the broader 11-kilometre historic mine trend. The high grade and free gold epizonal mineralization targeted by historic miners is now becoming evident from Mawson’s diamond drilling. A full suite of gold and antimony assays are now presented for the first time in Table 1 below shows better high-grade results from individual structures.

At Sunday Creek, historic gold mining occurred between 1880-1920 over a greater than 11 kilometre trend. Drilling during 1990-2000s focused on shallow, previously mined surface workings, covering an area of 100 metres in width, 800 metres length but, only to 80 metres average depth. As such, the entire field remains open along strike and to depth. Apollo was the original deepest shaft to 100 metres in the late 1800s in a series of sheeted stibnite-rich veins, predominately hosted within a felsic dyke that broadly controls gold distribution. Two diamond drill holes (MDDSC0011-12) from the Gladys and Apollo areas are reported here (Tables 1-4, Figure 1):

Mineralization at Sunday Creek is hosted in late-Silurian to early-Devonian-aged shales and siltstones containing a series of dykes of felsic-intermediate composition. Gold is concentrated mainly in and around the EW to NE-SW trending felsic dykes, within predominately NW oriented brittle multiple sheeted veins and cataclastic zones. Individual high-grade quartz-stibnite veins at Apollo and Golden Dyke, and cataclastic zones at Gladys were the focus of historical mining at Sunday Creek. These zones have been proven to continue to depth by Mawson. Broader vein-hosted and cataclastic mineralization grading less than 15 g/t gold appears untouched by the historic miners.

Mawson has now completed fourteen drill holes (MDDSC001-014) for 2,487 metres at the Sunday Creek gold. Drilling continues. Assays from 12 out of the 14 completed holes have been released. Geophysical surveys (3D induced polarization and ground magnetics) have been completed. A 2,500-point soil sampling program at Sunday Creek has commenced extending east-northeast from drilling areas to test the 11 kilometre trend of historic epizonal dyke-hosted mineralization within Mawson’s tenured areas.

Technical and Environmental Background

Tables 1–4 provide collar and assay data. The true thickness of the mineralized interval is interpreted to be approximately 70% of the sampled thickness. Gold-only intersections are reported with a lower-cut of 0.5 g/t gold over a 2.5 metre width except on the edge of calculated intervals where 1 metre @ >2.0 g/t gold was applied. No upper cut-off was applied.

A diamond drill rig from contractor Starwest Pty Ltd was used in the program. Core diameter is HQ (63.5 mm) and oriented with excellent core recoveries averaging close to 100% in both oxidized and fresh rock. After photographing and logging in Mawson’s core logging facilities in Nagambie, intervals were diamond sawn in half by Mawson personnel. Half core is retained for verification and reference purposes. Analytical samples are transported to On Site Laboratory Services’ Bendigo facility which operates under both an ISO 9001 and NATA quality systems. Samples were prepared and analyzed for gold using the fire assay technique (25 gram charge), followed by measuring the gold in solution with flame AAS equipment. Samples for multi-element analysis use aqua regia digest and ICP-MS methods. The QA/QC program of Mawson consists of the systematic insertion of certified standards of known gold content and blanks within interpreted mineralized rock. In addition, On Site inserts blanks and standards into the analytical process.

Gold Equivalent Calculation

It is the opinion of Mawson that all the elements included in the metal equivalent calculation have a reasonable potential to be recovered. The gold equivalent (AuEq) was calculated based on commodity prices as 21 March 2021. The Au Eq. formula is as follows: Au Eq. (g/t) = (Au g/t) + (XX * Sb%), where XX = (US$5,600/100) / (US$1,750/31.1035) and the gold price = US$1,750/oz and antimony price = US$5,600/tonne.
