2018 Outlook

In addition to the ongoing resource upgrade and resource expansion drilling, the company filed Pre-Feasibility 43-101 Technical Report March 29, 2018, the results of which are highlighted in the Technical Studies Press Release dated March 21, 2018. A maiden Reserve of 893,000 ounces was declared for the Triangle Zone, within Measured and Indicated Resources of 1.3 million ounces with a further 1.3 million ounces of Inferred Resources. The technical report outlines an initial seven year mine life with production averaging 117,000 ounces per year. Exploration for 2018 is budgeted at $7 million.

Capital expenditures at Lamaque in 2018 are forecast to be $120 million, including $20 million of capitalized mine operating costs. The Company expects to extract roughly 200,000 tonnes of ore grading 8.03 grams per tonne gold, containing approximately 40,000 ounces and anticipates toll milling a portion of the ore and producing 25,000 to 35,000 ounces.

Commercial production remains forecast for 2019.

Geology and mineralization

The Lamaque project consists of the newly-discovered Triangle gold deposit located only 2.5km south of the historical world-class Lamaque and Sigma Mines, which are also on the property and produced over 10Moz of gold. The Triangle deposit is located in the Val d’Or mining camp, at the eastern end of the prolific Southern Abitibi Greenstone Belt. The deposit is an Archean greenstone-hosted orogenic lode gold deposit. Gold is found within quartz-tourmaline-carbonate veins, which are hosted within a series of sub-parallel sub-vertical shear zones centered around a steeply plunging cylinder-shaped porphyritic diorite (“The Triangle Plug”), which intrudes the mafic volcanic stratigraphy of the Val d’Or formation. Individual gold bearing veins and associated alteration are on average 4-5m thick, sub-vertical and extend 500-700m horizontally and vertically and have a fully diluted average grade of approximately 7 g/t Au. To date, seven structures have been identified by drilling from surface to around 1,000m vertical depth. Secondary structures or splays from these principal shear zones can also host significant gold but are typically less extensive and more discontinuous. A recent deep drilling program has been successful in demonstrating the mineralized system extends to at least 2km below surface.


The Triangle deposit is typical of the high-grade orogenic gold deposits found in the Val-d’Or camp and the greater Eastern Abitibi region. Numerous exploration targets occur within the Lamaque project area, both at depth at the Triangle deposit and associated with other nearby occurrences. 34,000 meters of exploration drilling is planned in 2018 to test those targets.
