HARFANG EXPLORATION ANNOUNCES SIGNIFICANT GOLD, COPPER AND SILVER IN CHANNEL SAMPLING ON ITS SERPENT PROPERTY, JAMES BAY (QUÉBEC)

Montréal, October 11, 2018. Harfang Exploration Inc. (“Harfang”) (TSX-V: HAR) is pleased to report the results of the Summer 2018 exploration campaign on its Serpent property in James Bay. Channel sampling completed in August on two mineralized showings returned significant gold, copper and silver values. The Langelier showing assayed 91.48 g/t Au over 0.45 m in a boudinaged quartz vein (with visible gold) enclosed in a diorite-hosted shear zone. The Mista showing assayed 1.12% Cu, 0.23 g/t Au and 8.68 g/t Ag over 10 m, including 2.09% Cu, 0.45 g/t Au and 16.4 g/t Ag over 4 m in a quartz vein associated to foliated and sheared tonalite and diorite. Both showings are found in the Langelier Complex (figure 1).

The Langelier showing corresponds to an ENE-WSW shear zone hosted in foliated to gneissic quartz-bearing diorite. The sheared corridor extends for at least 75 m and is up to 2 m wide. It contains folded and boudinaged quartz veins with visible gold. Grab samples collected in 2018 in the structure returned up to 17.79 and 54.75 g/t Au. Grab samples are selected samples and are not necessarily representative of the mineralization enclosed on the property.

The Mista showing refers to quartz veining in foliated to highly sheared tonalite and diorite. The mineralized structure, reaching up to 10 m, strikes in a WNW-ESE direction for at least 280 m (figure 2). Channel sampling was done across the width of the largest quartz vein whose edges could not be excavated by manual trenching. Quartz veins at the Mista showing are characterized by recrystallized quartz and interstitial sulfides such as chalcopyrite with traces of bornite, covellite, chalcocite, pyrite and/or pyrrhotite. Grab samples collected in 2018 on this showing returned up to 3.04% Cu, 1.93 g/t Au and 20.0 g/t Ag.

Harfang discovered the Langelier and Mista showings in 2017 and results, grading up to 4.11 g/t Au and 2.11% Cu in grab samples, were published in a press release dated on October 11, 2017. Several other mineralized sites (>0.1 g/t Au and >0.1% Cu) exist along similar structural corridors in other underexplored sectors of the property.

These encouraging results prompted Harfang to continue its field investigation this Fall season. More prospecting will be accomplished along the kilometric long structural corridors outlined so far on the property. Small-scale soil and till surveys will be completed in the immediate surroundings of both showings. Our main objective with these surveys is to test the geochemical signature of the known mineralization before proceeding to larger scale surveys or any other exploration programs. Uncommon in the James Bay territory, this type of mineralization could represent a new metallogenic setting.

About the Serpent property

The Serpent property, wholly owned by Harfang, contains 255 claims covering 13,197 ha. It is divided into two blocks of claims. The property is located 80 km SSE of the Radisson locality and only 10 km east of the James Bay Road. Its eastern limit is contiguous with the Sakami gold project (Quebec Precious Metals Corporation). Lithologies are dominantly associated to the Langelier Complex which includes foliated and gneissic tonalite and diorite interpreted as the Archean crustal basement onto which volcano-sedimentary assemblages were deposited.

Quality control

All rock samples were sent to Laboratoire Expert (Rouyn-Noranda) to be analyzed for chemical elements Au-Ag-Cu-Zn-Pb. These five elements were analyzed by atomic absorption following pyroanalysis for gold and four acid total digestion for other metals. Samples with gold values above 1 g/t were reanalysed by gravimetry. For channel samples, the results obtained following these methods were used for the calculation of mineralized intervals. The sampling procedure and interpretation of the results were done by qualified employees using a QAQC program conformed to the best practices in the industry including the use of standards and blanks.

About Harfang

Harfang is a mining exploration company whose primary mission is to discover new gold districts in the province of Québec. Harfang’s development model is based on the generation of new mining projects and on the establishment of partnerships with major exploration and mining companies to advance its exploration projects.
