MAS GOLD Extends Mineralization at its 100% Owned Greywacke Property

Vancouver, May 6, 2021 – MAS Gold Corp. (TSX.V: MAS) (“MAS Gold” or the “Company”) is pleased to provide a summary of assay results from the 2021 winter drill program undertaken on its Greywacke Lake Property in the La Ronge Gold Belt, Saskatchewan. A total of 2,912.9 meters were drilled in 15 holes completed.

The 2021 Greywacke Lake winter drill program was designed to provide infill and step out data points in preparation for an upgraded Greywacke North resource estimate and to test for extensions of gold mineralization at the Greywacke South, Central and Lyons showings.


Greywacke North deposit:

  • DDH GW21-128 and GW21-129 (Figures 1, 2, 5 & 6) confirm high grade mineralization:
    • DDH GW21-128 hosts 7.36 g/t over 9.9m*
    • DDH GW21-129 hosts 3.79 g/t over 5.53m
  • DDH GW21-136 (Figure 1, 3 & 5) continues Au mineralization at depth:
    • 1.39 g/t Au over 10.12m; including 2.19 g/t Au over 3.12m.

Greywacke South Zone:

  • DDH GW21-142 (Figure 1, 4 & 5) shows continued the down dip extension:
    • 3.8 g/t over 8.16m; including 5.7 g/t over 2m and 10.87 g/t over 1m.
  • DDH GW21-141 (Figures 1 & 5) designed to test for mineralization within the Greywacke Central zone, intersected Au mineralization of:
    • 2.34 g/t Au over 1.5 m.

David Tupper, Vice President of Exploration, comments, “The 2021 winter drill program provides MAS Gold with important new analytical data and new material from mineralized intercepts for upcoming metallurgical analysis work to be incorporated into an upgraded resource estimate for the Greywacke North deposit. The updated resource estimate and the new metallurgical work are key to supporting the recently announced Preliminary Economic Assessment (PEA), which will be completed in late 2021.

Mr. Tupper continues “The 2021 results also point towards the potential of the Greywacke South zone as an area that could add to the known resources of the property.”

2021 North Lake Winter Drill Program

The core sampling of the North Lake Deposit has now concluded with all 2,196 samples sent to TSL Laboratories in Saskatoon, Saskatchewan. MAS Gold expects assay results on all 10 diamond drill holes over the coming weeks. The objective of the program was to expand the resource at depth by targeting down dip extensions of the deposit


Au analysis is by fire assay,;Au values <3000 ppb were reanalyzed with Gravimetric finish

Sample Quality Assurance / Quality Control

Sample intervals were laid out with the objective of capturing homogenous lithology and not cross any significant alterations with the sample guideline of a minimum samples size of 0.50m and a maximum sample size of 2.0m. All core is logged, tagged, photographed, cut and stored in a secure facility on the Greywacke Lake Property.

Samples were marked on core with assigned sample number from a pre-numbered sample tag. These markings and stapled sample tags were placed at the start of the intervals. Drill core was cut using a core saw with a diamond bit blade using fresh flowed water to ensure no possible contamination between samples. Care was taken to ensure that the same half of the core was sampled for the entire sample interval to maintain consistency and no biases in the assay results. Core duplicates were generated by quarter sampling core.

MAS Gold utilized TSL labs which is a registered laboratory with a current ISO accreditation. TSL is accredited to international quality standards through the International Organization for Standardization/ Internal Electronic Commission (ISO/IEC), ISO17025 (Testing and Calibration Laboratories).

All rock sample preparation conducted by TSL at their preparation facility in Saskatoon, SK. Rock samples were dried, crushed to 95% passing 1.70 mm, creating ~1000g sample. Sample is then split and pulverized to 95% passing 106 microns. The pulveriser was cleaned using a sand wash after every samples as to avoid any potential contamination.

Core analyzed by TSL was handled at their facility in Saskatoon, SK. Core samples were analyzed for gold using FA/AA of 30g as well as multi-element ICP-MS with a multi-acid digestion. Gold Assays returning greater than 3 g/t (ppm) where analyzed using gold fire assay with gravimetric finish. Reject pulps are saved and stored for potential, future metallic screening or other analyses.

An independent QAQC program was conducted by inserting duplicates, certified reference materials, and pulp blanks. This was used to test for natural variability/sampling bias / testing the lab for homogeneity during sample preparation processes within the lab as well as testing the precision and any possible contamination from the lab. Additionally, TSL labs also includes an internal QAQC duplicate on gold analyses. Roughly ~12-13% of samples (e.g., ~12-13 samples out of 100 samples) are external QAQC samples.
