- Indicated pit constrained resources of 560,000 ounces of gold - Inferred pit constrained resources of 1,750,000 ounces of gold - 27,000 metre infill and expansion drilling campaign at Goldlund expected to commence by end of January 2017
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan. 9, 2017) - First Mining Finance Corp. ("First Mining" or the "Company") (TSX VENTURE:FF)(OTCQX:FFMGF)(FRANKFURT:FMG) is pleased to announce the release of an initial Resource estimate for its Goldlund Gold Project ("Goldlund" or the "Project") located near the town of Sioux Lookout in northwestern Ontario. The Company assumed control of the Goldlund project through its amalgamation with Tamaka Gold Corporation ("Tamaka") on June 17, 2016. The Resource estimate was prepared by WSP Canada Inc. ("WSP") of Sudbury, Ontario and has an effective date of September 20, 2016. A technical report for this initial Resource estimate for Goldlund, prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"), will be filed by the Company on SEDAR within 45 days of the date of this news release.
Highlights of the Goldlund Deposit
- 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 Company expects to commence a 27,000 metre drilling campaign at Goldlund by the end of January 2017. The goal of the drilling campaign is to upgrade and expand the Mineral Resources at the Goldlund deposit.
Keith Neumeyer, Chairman of First Mining stated, "In comparing the Goldlund project to the rest of our portfolio, we believe that Goldlund has the potential to become one of our cornerstone projects. We believe that we have the potential to expand the Goldlund resource with additional drilling and the project is also adjacent to existing infrastructure such as a highway and electricity, which make this project highly compelling. Going forward I'm excited to see how the results from our 2017 winter drilling campaign at Goldlund unfold as we seek to further define the resource on this 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"). 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, which are currently owned by First Mining through its wholly-owned subsidiary, Tamaka. The Goldlund deposit is currently defined by surface and underground diamond drilling, together with underground development.
The Goldlund deposit can be classed as an Archean orogenic or lode gold system, although not the classic type of single or multiple veins of quartz-ankerite-pyrite in greenstone terranes typical of eastern Canada. Gold mineralization at Goldlund, as currently understood, is contained in a stockwork system of 1 to 20 centimetre wide quartz-carbonate-pyrite veinlets hosted by a parallel set of northeast striking, steeply dipping granodiorite and rhyolite porphyry dikes 15 to 60 metres in width in basaltic volcanic rocks. The vein stockworks are restricted to the more brittle granodiorite dikes and rapidly diminish in thickness and frequency outward from the granodiorite-basalt contact. The gold-bearing, stockworked granodiorite dikes vary in thickness from 14 to 60 metres in width, dip 80° to the southeast and can be traced over a 3 kilometre strike length, whereas in the vertical, the dikes have been explored in drillholes to a depth of 400 metres. The dikes themselves occur at outcrop over an 18 kilometre strike length and will be the subject of future exploration in the Goldlund property package.
First Mining compiled all the data used in completing the Mineral Resource from original source drillhole documents and from plan and section originals and copies. Goldlund has been tested by 1,816 historic drillholes and underground shafts, ramps and drifts. However, only drillholes within the areas of interest and with exploration potential were included in the database. In addition to the drillhole database, a dataset containing underground wall sampling intervals was included. Wall sampling was conducted as continuous samples on both walls and at times at chest and back heights. The wall sampling data was converted into drillhole format to supplement the dataset.
All resource estimations were conducted using Surpac version 6.6.
Based on historical data and samples collected by First Mining, a specific gravity of 2.81 was assigned to the volcanics and a specific gravity of 2.72 was assigned to the mineralized dikes.
Three-dimensional wireframe models of mineralization were developed for the seven zones based on: geology, alteration, a gold cut-off of greater than 0.2 g/t and a minimum 2 metre horizontal width. Areas of drift development in mineralization were also created. Sectional interpretations were digitized in Datamine Studio software, and these interpretations were linked with tag strings and triangulated to build the three-dimensional solids by First Mining. WSP imported the Datamine solid files into Surpac for use.
The mineralized zones are generally contiguous, however, due to several transverse faults throughout the Project, mineralization may often be terminated or shifted along these planes in one or more directions.
The seven zones (Zones 1 through 8, no Zone 6), which are part of the Mineral Resource, were sampled by a total of 60,844 drillhole intervals and 279 wall sample intervals.
Individual block models were established in Surpac for all seven zones using one parent model as the origin.
Drillhole spacing varies with the majority of the drilling tightly spaced from 30 metres. A block size of 10 x 10 x 10 metres was selected in order to accommodate the more closely spaced drilling and the narrow nature of the mineralization.
Sub-celling of the block model on a 1 x 1 x 1 allows the parent block to be split once in each direction to more accurately fill the volume of the wireframes, thus more accurately estimate the tonnes in the resource.
The interpolations of the seven zones were completed using the estimation methods: nearest neighbour (NN), inverse distance squared (ID2) and ordinary kriging (OK). The estimations were designed for four passes. In each pass, a minimum and maximum number of samples were required as well as a maximum number of samples from a borehole in order to satisfy the estimation criteria.
A pit shell was generated using the Lerch-Grossman (LG) algorithm in Whittle. Table 3 is a summary of the parameters used in the pit optimization process. WSP has concluded that the optimized pit shell suggests a resource using a 0.4 g/t cut-off and a US$1,350 gold price with a 5.8 strip ratio would be acceptable.

| Item | Unit | Amount |
| Gold Price | US$/troy Ounce | 1,350 |
| Mining Cost (open pit) | US$/tonne of material | 2.00 |
| Processing cost | US$/tonne of material | 12.90 |
| G&A Costs | US$/tonne of material | 2.50 |
| Mettallurgical Recovery | Percent | 93% |
| Pit Slope | Degrees | 48 |
The Goldlund database has gone through several validations including 10% of the total database extant prior to 2010. The error rate of the initial dataset was found to exceed 1%. The entire dataset was subsequently examined and corrected and a second review returned no errors.
A total of 100% of the assay data received between 2011 and 2014 were checked against the digital assay certificates with no discrepancies found. The same is true of collar coordinates, survey data, and lithology intervals.
The drillhole data database underwent a final validation during loading into Surpac 6.6. Any errors identified in the routine were checked against the original logs and corrected.
From 2011 to 2014 a total of thirty one surface drillhole collars were confirmed by the author using a Garmin hand-held GPS unit having an accepted resolution of ±5 metres. An additional 10 collar locations were verified by a different QP in 2013 using a similar GPS unit.
In 2010 and 2013 a total of thirty five samples of mineralized drill core were collected and delivered by the author to Actlabs and Accurassy in Thunder Bay for preparation and analysis.
The check samples reproduced the grades in the Goldlund drillholes as accurately as would be expected in an Archean lode gold deposit.
Pulps from a further thirty mineralized intervals in the 2013-2014 drill program were collected and delivered by WSP to ALS Minerals in Sudbury, Ontario for analysis for gold using a 50 gram aliquot in a FA/AA finish. In addition a QC test was performed on each sample to test the pulp fineness.
WSP concluded the sampling practices applied at Goldlund meet current industry standards and that the sample database provided is suitable to support the resource estimation.
