TMAC Resources drills 1.8 m of 193.3 g/t Au at Doris

2019-08-14 09:59 ET - News Release

Mr. Jason Neal reports

TMAC ANNOUNCES GROWTH OF DORIS BTD EXTENSION ZONE AND FIRST RESULTS FROM DORIS REGIONAL PROGRAM

TMAC Resources Inc. has provided an interim exploration update, including surface exploration drilling results at Doris and initial drilling results from the Doris regional program, including high-grade gold intercepts within 15 metres of surface.

Doris BTD extension (drilling from underground)

TMDBE-19-50046:

  • 193.3 grams per tonne (g/t) gold (Au) over 1.8 metres;
  • And 42.0 g/t Au over 0.6 metre;
  • And 333.0 g/t Au over 0.6 metre.

TMDBE-19-50500:

  • 15.6 g/t Au over 4.4 metres.

TMDBE-19-50501:

  • 105.8 g/t Au over 1.5 metres.

TMDBE-19-50507:

  • 110.8 g/t Au over 10.8 metres;
  • And 7.5 g/t Au over 3.1 metres.

Doris Valley highlights (drilling from surface)

TMRDC-19-00002:

  • 3.7 g/t Au over 0.4 metre;
  • And 7.7 g/t Au over 7.5 metres;
  • Including 11.8 g/t Au over 4.3 metres.

TMRDC-19-00003:

  • 5.3 g/t Au over 4.8 metres;
  • Including 12.5 g/t Au over 1.6 metres.

TMRDC-19-00004:

  • Nine g/t Au over 8.5 metres;
  • Including 15.4 g/t Au over 2.3 metres.

TMRDC-19-00005:

  • 4.6 g/t Au over 1.3 metres;
  • And 97.6 g/t Au over 0.3 metre.

Jason Neal, president and chief executive officer of TMAC, stated: "We continue to have strong drilling results in the growing Doris BTD extension zone, including in one hole 110.8 grams per tonne of gold over 10.8 metres. Additionally, initial drill results in a new zone we are calling Doris Valley, as part of our Doris regional program, are intriguing and we are evaluating our follow-up strategy. At Doris Valley, assays from two holes in the vicinity of good surface grab samples included promising intercepts within the first 15 metres from surface. The first encountered nine grams per tonne of gold over 8.5 metres, including 15.4 grams per tonne of gold over 2.3 metres, and a second had 5.3 grams per tonne of gold over 4.8 metres, including 12.5 grams per tonne of gold over 1.6 metres. There is obviously more work required to follow up on this initial success, but this highlights the potential to grow our mineral inventory through even modest exploration investment."

Doris -- exploration drilling

Subsequent to the July 15, 2019, second quarter exploration news release, surface exploration drilling continued at Doris, north of the known deposit in the Doris Valley. Near-surface drilling was targeted below historical surface outcrop samples, which included 62.5 grams per tonne of gold and 113.1 grams per tonne of gold and drilling at depth was targeted 325 metres north along the potential strike of the Doris BTD extension zone. To date, five holes have intersected the Doris deposit stratigraphy, with mineralized quartz veins at the iron-titanium tholeiite/magnesium tholeiite contact suggesting the Doris BTD stratigraphy continues at least 375 metres along strike to the north. Highlights from assays received from initial drilling include near-surface drill hole TMRDC-19-00004, returning nine grams per tonne of gold over 8.5 metres, including 15.4 grams per tonne of gold over 2.3 metres, and deeper drill hole TMRDC-19-00002, returning 7.7 grams per tonne of gold over 7.5 metres, including 11.8 grams per tonne of gold over 4.3 metres with visible gold noted. Assay results from the initial five drill holes are summarized in an attached table and drill hole locations are illustrated. Additional drilling is required to determine the relationship to the known Doris deposit and if this a continuation of the Doris North BTD extension, a fault offset block, or a new mineralized zone. These results represent a significant stepout from the currently defined mineral resources and increases the company's confidence in the long-term sustainability of Doris operations.

Also, at Doris mine, underground expansion and infill drilling is continuing on the high-grade Doris BTD extension zone and additional assays have been received since the July 15, 2019, news release. Highlights from the underground expansion drilling program include drill hole TMDBE-19-50046, returning 193.3 grams per tonne of gold over 1.8 metres, 42.0 grams per tonne of gold over 0.6 metre and 333.0 grams per tonne of gold over 0.6 metre and drill hole TMDBE-19-50501 returning 105.8 grams per tonne of gold over 1.5 metres. Highlights from infill drilling at the south end of the zone, near the current underground access development, include drill hole TMDBE-19-50507 returning 110.8 grams per tonne of gold over 10.8 metres and 7.5 grams per tonne of gold over 3.1 metres. Assay results for BTD extension drill holes received since the previous news release are summarized in an attached table. Underground infill and expansion drilling on the BTD extension will continue through the remainder of 2019.

Sample preparation, analysis and quality assurance/quality control

For the Doris drilling campaigns, samples were prepared at ALS Laboratories in Yellowknife, NWT, and assayed at its Vancouver, B.C., laboratory (an ISO/IEC 17025 accredited lab for gold analysis). Analysis for gold is completed on sawn half-core samples (NQ) using 50-gram fire assay with atomic absorption (AAS) finish. Samples with higher-grade gold (greater than 100 grams per tonne) are reassayed using the pulp and fire assay with gravimetric finish procedures. Samples with visible gold and surrounding samples are analyzed using screen metallics (1,000 grams of material is screened to 100 microns, with all plus-100-micron material analyzed and two samples of minus-100-micron material analyzed by 50-gram fire assay with AAS finish, results are averaged based on weight). Chip samples and select drill hole samples from Doris were prepared and analyzed at the internal laboratory located at the Doris mine site (non accredited lab), operated by SGS SA. Analysis for gold is completed using 30-gram fire assay with atomic absorption (AAS) finish. Samples with higher-grade gold (greater than 10 grams per tonne) are reassayed using the pulp and fire assay with gravimetric finish. Samples with visible gold are selected to go directly to fire assay with gravimetric finish. The company control checks include the insertion of standard reference materials and blank samples to monitor the precision and accuracy of the assay data.

About TMAC Resources Inc.

TMAC Resources operates Hope Bay located in Nunavut, Canada. The property and operations are remote but not isolated, serviced by both a port and airstrip.
