MONTREAL, Dec. 10, 2018 (GLOBE NEWSWIRE) -- Harfang Exploration Inc. (“Harfang”) (TSX-V: HAR) is pleased to announce that many till samples collected during the Fall 2018 survey in the Mista showing area (Serpent Property) contain anomalous amounts of gold grains. The new exploration targets generated north (or up-ice) of the till survey led to the acquisition of 40 claims by map designation north of Mista (Figure 1).
A total of 27 samples were collected at an approximate spacing of 500 m in this till survey, covering a 2.6 km x 2.2 km area. The main objective of the survey was to test the geochemical signature of the Mista zone in the Quaternary deposits and to identify potential mineralized corridors in the western extension of the showing. Till results clearly demonstrate that the quantity of gold grains (including pristine grains) are more significant in the northwestern and southwestern portions of the survey. The gold-bearing samples (up to 11 gold grains in total) in the northwest contain scheelite (up to 30 grains), whereas those in the southwest (up to 17 gold grains in total) contain loellingite (up to 7 grains) suggesting two distinct sources. Both scheelite and loellingite are indicator minerals for gold deposits. Calculated concentrations of visible gold in heavy mineral concentrates range between 0.1 and 249.2 g/t Au for eight samples. This very high calculated grade is caused by a coarse gold grain reaching 1.43 mm x 0.55 mm x 0.50 mm. The current interpretation based on a southwest directed glacial dispersal train suggests two potential sources for the auriferous tills. One would be linked to the loellingite, while the other is associated to the scheelite. No exploration work has ever been done in the source region of the scheelite grains (Figure 2).
In light of these positive results obtained from the Fall till survey, Harfang will proceed with additional similar surveys. First, the extent of the Fall survey will be increased and completed with infill samples in order to delineate the sources of auriferous tills. Second, other areas of interest (e.g. the Langelier showing) will need to be covered with a similar survey.
Highly motivated by Cu-Au-Ag mineralizations at Mista and by gold-bearing tills, the Corporation is planning a geophysical survey in this part of the Serpent Property. Future fieldwork will also include prospecting and geological mapping. The recent claim addition between the Langelier and Mista showings gives Harfang the exclusive rights for exploration work on this outcropping land which has never been explored.
About the Serpent Property
The Serpent Property, wholly owned by Harfang and without NSR royalties, now contains 295 claims covering 15,267 ha. The property is located 80 km SSE of the Radisson locality and only 10 km east of the James Bay Road. Lithologies are dominantly associated to the Langelier Complex which includes foliated and gneissic tonalite and diorite interpreted as the Archean crustal basement onto which was deposited a volcano-sedimentary assemblage partially preserved on the property.
Two significant mineralized zones were discovered during recent exploration campaigns, namely the Langelier showing (91.48 g/t Au over 0.45 m [channel]) and the Mista showing (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 [channel]).
Quality Control
Till samples were collected by the Harfang team and sent to Overburden Drilling Management [ODM] (Nepean, Ontario). This laboratory proceeded with the grain count, with the identification of some indicator minerals, and with the determination of gold grain shape from the non-magnetic heavy mineral concentrates. Quantities of grains mentioned in the text and shown in figures are not normalized to 10 kg since all samples submitted to ODM had very similar weights between 12.2 and 14.5 kg.
About Harfang
