First Mining Finance Corp. Completes Fall Drill Program at Pickle Crow Project

Highlights:

• Hole PC-16-306 intersected 1.28 g/t over 12.70 metres including 15.14 g/t over 0.70 metres in the middle vein zone of the No. 15 Vein.
• Visible gold was intersected in Hole PC-16-306 in the lower vein zone of the No. 15 Vein.

Note: Reported widths are drilled core lengths; true widths are unknown at this time. All assays are performed by Accurassay Laboratories of Thunder Bay, Ontario. Assay values are uncut.

A total of nine holes comprising approximately 1,300 metres were drilled during the fall 2016 program. The drill program targeted several shallow, high-grade vein and banded iron formation hosted targets in the core mine trend. The objective of this exploration program was to test extensions of known vein zones and discover new high-grade gold mineralization.

Gold mineralization was encountered in seven of the nine drill holes and visible gold was intercepted in the lower most vein zone of the No. 15 Vein structure. A 0.30 metre section of drill core from the lower vein zone which included the visible gold was not assayed as it was retained for display purposes, hence the reported intercept of 1.15 g/t gold over 8.19 metres excludes this interval and the 0.30 metre section was included at zero grade.

Commenting on the results, Patrick Donnelly, President of First Mining stated, "The recent drilling program at Pickle Crow demonstrates that there is widespread gold mineralization at the property. Given the success of this drilling program the Board of Directors has authorized a winter drilling campaign at Pickle Crow which is to be comprised of four additional holes totaling approximately 1,000 metres. We look forward to seeing how this second drilling campaign unfolds."

All assays are performed by Accurassay Laboratories of Thunder Bay, Ont. Samples were analyzed by using 50-gram fire assay with an atomic absorption finish. Samples greater than 10 grams per tonne or with visible gold were analyzed by 1,000-gram pulp metallic analysis with a gravimetric finish. All assays reported are uncut. Reported widths are drilled core lengths, and true widths are unknown at this time. Accurassay Laboratories is independent of First Mining and has no relationship with First Mining.

QA/QC Procedures

First Mining implemented the following QA/QC procedures for the Pickle Crow Gold Project drill program.

NQ diameter (47.6 mm) drill core is logged then sawn in half onsite, with one half bagged and labelled and the other half placed in core boxes to serve as a permanent record and stored in a secure on-site facility. All samples are shipped from the site via Manitoulin Transport to the Accurassay Laboratories facility in Thunder Bay, Ontario, for crushing, pulverization and pulp preparation. Accurassay Laboratories is independent of First Mining and has no relationship with First Mining.

All samples sent for analyses are prepared using a jaw crusher, which is cleaned with compressed air between samples, resulting in 70% of the sample passing through a 10 mesh screen. A 1,000 gram split of the crushed sample is then pulverized with 85% passing through a 200 mesh screen. Fire assays are performed using 50 grams of sample with assays equal to or greater than 5 g/t calculated gravimetrically, and lower grade samples measured by atomic absorption (AA). All samples greater than 10 g/t are additionally sent for screen metallics analysis using the remainder of the pulp (~950 grams of sample).

Blanks, standards (one high-grade, one mid-grade, and one low-grade), field duplicates (1/4 split cores), and crush duplicates are inserted sequentially at least every 8^th sample into the drill core samples before shipment. Standards consist of a high-grade (~13 g/t Au), a mid-grade (~5 g/t Au), and a low-grade (~1 g/t Au) gold standard from Geostats Pty. Ltd. of Fremantle, Western Australia, as well as blanks from Nelson Granite of Kenora, Ontario.

A more detailed description of the QA/QC procedures employed may be found in Section 14.2 (PC Gold Data Verification) of the NI 43-101 resource estimate for the Property entitled "A Mineral Resource Estimate for the Pickle Crow Property, Patricia Mining Division, Northwestern Ontario, Canada", dated June 2, 2011.
