Table 2. Drill Hole Locations

Gold observed during the current drilling program at Goldlund occurs both as fine disseminations in quartz vein stockworks and as more discrete larger grains up to 2 mm spatially associated with pyrite in the quartz veins. Calaverite, a gold telluride mineral, has been noted occasionally in higher grade intervals on fracture surfaces in the quartz veins. Higher grade gold distribution in the granodiorite dike is often, but not always, associated with zones of more intense quartz stockworking and potassic alteration. Figure 2 above displays a cross-section of the geology and gold mineralization with drill holes GL-17-02 to GL-17-08.

QA/QC Procedures

The QA/QC program for the 2017 drilling program at Goldlund consists of the submission of duplicate samples and the insertion of certified reference materials and blanks at regular intervals. These are inserted at a rate of one standard for every 20 samples (5% of total) and one blank for every 30 samples (3% of total). The standards used in the 2017 program consist of 5 different gold grades ranging from 1 to 9 g/t, and are sourced from CDN Resource Laboratories in Langley, BC. Blanks have been sourced locally from barren granitic material.

Field duplicates from quartered core, as well as 'coarse' or 'pulp' duplicates taken from coarse reject material or pulverized splits, are also submitted at regular intervals with an insertion rate of 4% for field duplicates and 4% for coarse or pulp duplicates. Additional selected duplicates are being submitted for screened metallic fire assay analysis and to an umpire lab for check assaying. SGS also undertake their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration.

ABOUT THE GOLDLUND PROJECT

The Goldlund deposit is situated within a land package of approximately 280 square kilometres (28,000 hectares) referred to as the Goldlund Gold Project. The Property has a strike-length of over 50 kilometres in the Wabigoon Subprovince. Goldlund is an Archean lode-gold project located in northwestern Ontario, approximately 60 kilometres from the township of Dryden. The claims that make up the land package cover the historic Goldlund and Windward mines.

On January 9, 2017, the Company announced an initial mineral resource estimate for Goldlund. At a 0.4 g/t Au cut-off grade, the Goldlund deposit contains pit constrained Indicated Resources of 9.3 million tonnes at 1.87 grams per tonne or 560,000 ounces of gold. At a 0.4 g/t Au cut-off grade, the Goldlund deposit contains pit constrained Inferred Resources of 40.9 million tonnes at 1.33 grams per tonne or 1,750,000 ounces of gold. The technical report for this resource estimate has been filed on SEDAR and is also available on the Company's website at www.firstminingfinance.com.
