Overview and locality

The Lamaque Complex operation consists of the Triangle gold deposit located only 2.5 km south of the historical world-class Lamaque and Sigma Mines, which are also on the property and produced over 10 Moz 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 4-5 m thick, sub-vertical and extend 500-700 m 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 1,000 m 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 2 km below surface.

A brief history

Lamaque Complex

The Triangle and Ormaque orogenic gold deposits are part of the Lamaque Mining Complex.
Historically, the Sigma and Lamaque mines produced a combined 10 Moz Au and occur within a 2.5 km radius of Triangle and Ormaque.
Integra Gold Corporation discovered the Triangle deposit in 2010. Eurasia Minerals Corporation purchased Integra in 2017 and advanced development to commercial production in March 2019.
Subsequently, during summer 2019, Eurasia Minerals Corporation discovered the Ormaque deposit.
Exploration is focused on supporting the conversion of resources in the deeper veins at Triangle and at Ormaque.
Exploration is also targeting and drill testing for new Inferred Resources in the existing mine infrastructure area, as well as exploring for satellite deposits in the district that can feed the Sigma mill.
