First Mining Announces Exploration and Infill Drilling Results for Its Goldlund Gold Project

VANCOUVER, B.C., Feb. 08, 2018 (GLOBE NEWSWIRE) -- First Mining Gold Corp. (“First Mining” or the “Company”) (TSX:FF) (OTCQX:FFMGF) (Frankfurt:FMG) is pleased to announce the exploration and infill drilling results, comprising 14 drill holes, from its diamond drill program within Zones 1 and 5 (See Tables 1 and 2) at First Mining’s 100% owned Goldlund Gold Project (“Goldlund”), located near the town of Sioux Lookout in northwestern Ontario, Canada.

Drilling Highlights:

• Hole GL-17-128 intersected 3.0 metres of 10.76 grams per tonne gold
  • including 1.0 metre of 30.27 grams per tonne gold
• Hole GL-17-119 intersected 16.0 metres of 1.15 grams per tonne gold
  • including 2.0 metres of 3.69 grams per tonne gold
• Hole GL-17-126 intersected 10.0 metres of 1.50 grams per tonne gold
  • including 2.0 metres of 3.58 grams per tonne gold

Note:  Assaying for the 2017 and 2018 Goldlund drill programs are being done by SGS Canada Inc. (“SGS”) at their laboratories in Red Lake, ON. and Burnaby, BC.  Reported widths are drilled core lengths; true widths are unknown at this time.  Assay values are uncut.

The 2017/2018 drilling campaigns at Goldlund are designed to accomplish four significant objectives:

• Convert Inferred resources within the resource area (Zones 1, 5 and 7) into the Measured and Indicated resources category;
• Test drill deeper exploration targets within Zone 7;
• Identify and add additional mineralization within areas that are adjacent to the current resource boundary; and
• Test drill additional exploration targets within other areas (outside of the current resource boundary) within the Goldlund Gold Property.

On February 5, 2018, the Company released results of the four deep Zone 7 holes (GL-17-010, GL-17-051, GL-17-106 and GL-17-108). All four holes demonstrated that gold mineralization at Goldlund continues to considerable depths.

The 14 drill hole results (Figure 1) presented in this news release are from the following Zones:

• GL-17-114; GL-17-115; GL-17-118 and GL-17-119 are infill holes targeting the area between Zones 1 and 5. All four holes intersected gold mineralization;
• GL-17-116; GL-17-117 and GL-17-123 to GL-17-128 are also infill drill holes that are located within Zone 1. Six of the eight holes intersected gold mineralization; and
• GL-17-120 and GL-17-121 were exploration drill holes that were targeting potential additional hanging wall mineralization outside of the current resource area, south of Zone 5. Neither of these holes intersected gold mineralization.

In February 2018, First Mining will complete the remaining infill holes within Zones 1 and 5 and will then commence drilling regional exploration targets that are outside the current resource boundary.

Jeff Swinoga, the Chief Executive Officer of First Mining, stated, “These latest drill holes were designed to provide greater confidence in the gold mineralization which is currently confined within a strike length of only 2 to 3 kilometres, whereas the total estimated strike length is estimated to be approximately 30 kilometres. Our next focus will be to carry out exploration drilling on several highly prospective and underexplored areas of the Goldlund property.  I am very excited to see how these future drill results will support our confidence in the continued gold mineralization along strike at Goldlund.”

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 below displays a cross-section of the geology and gold mineralization for drill holes GL-17-125 to GL-17-127, and GL-17-116.

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.

Dr. Chris Osterman, P.Geo., COO of First Mining, is the “qualified person” for the purposes of National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and he has reviewed and approved the scientific and technical disclosure contained in this news release.

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 that was prepared by WSP Canada Inc. in accordance with NI 43–101.  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 g/t Au, 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 g/t Au, or 1,750,000 ounces of gold.  The technical report for this resource estimate, which is titled “Technical Report and Resource Estimation Update on the Goldlund Project” and is dated February 7, 2017, is available under the Company’s SEDAR profile at www.sedar.com, and is also available on the Company’s website at www.firstmininggold.com.

Cautionary Note to United States Investors

This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws.  Unless otherwise indicated, all resource and reserve estimates included in this news release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101”) and the Canadian Institute of Mining, Metallurgy, and Petroleum 2014 Definition Standards on Mineral Resources and Mineral Reserves.  NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission ("SEC”), and mineral resource and reserve information contained herein may not be comparable to similar information disclosed by U.S. companies.  In particular, and without limiting the generality of the foregoing, the term "resource” does not equate to the term "reserves”.  Under U.S. standards, mineralization may not be classified as a "reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.  The SEC's disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources”, "indicated mineral resources” or "inferred mineral resources” or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves” by U.S. standards in documents filed with the SEC.  Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.  U.S. investors should also understand that "inferred mineral resources” have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility.  It cannot be assumed that all or any part of an "inferred mineral resource” will ever be upgraded to a higher category.  Under Canadian rules, estimated "inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies except in rare cases.  Investors are cautioned not to assume that all or any part of an "inferred mineral resource” exists or is economically or legally mineable.  Disclosure of "contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves” by SEC standards as in-place tonnage and grade without reference to unit measures.  The requirements of NI 43-101 for identification of "reserves” are also not the same as those of the SEC, and reserves reported by the Company in compliance with NI 43-101 may not qualify as "reserves” under SEC standards.  Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
