Mangazeisky Silver Project


Mangazeisky Silver Project, Russian Federation

One of the highest grade silver project in the world; low cost, high return that is currently in the construction phase with silver commissioning currently underway

Highlights

  • 100% owned Mangazeisky Exploration licence covers a 35 km mineralised structural corridor, located approximately 400 km north of Yakutsk in the Republic of Sakha, Russia;
  • In September 2013, the Company was granted a 20-year Mining Licence to the Vertikalny deposit; and in September 2016, the Company was awarded a 7-year extension for its Exploration Licence, with no reduction in size and no minimal work requirement.
  • High grade NI 43-101 resources as of August 2017:
    • Reserve of 858 kt grading 809 g/t Ag and containing 22.31 Mozs of Silver;
    • Indicated resource of 1.304 Mt grading 1,079 g/t Ag and containing 35.95 Mozs Silver; and
    • Inferred resources of 1.495 Mt grading 504 g/t Ag and containing 23.46 Mozs Silver.
  • Strong Potential for additional high-grade feeder pits, within six km of Vertikalny deposit there are NI 43-101 MRE on three deposits and Russian compliant resources on many additional targets;
  • In August 2017, the Company announced an Updated Feasibility Study on the Vertikalny deposit and an amended PEA on the Mangazeisky North deposit, the Technical Report was filed on SEDAR under the Company’s profile.
  • As September 2017, the Project is significantly advanced with construction and the hot and cold commissioning work is well underway.

Location and Infrastructure

The Mangazeisky Silver Project is located in the north-central potion Yakutia Russia, approximately 400 kms north of the capital city of Yakutsk (population 300,000). The economic development of the region around the Mangazeisky Project is low with little or no infrastructure with limited access to the site, including seasonal winter road from December to April and for the remainder of the year the project is accessible primarily by helicopter or fixed wing aircraft from either Yakutsk or Batagai.

The closest village to the Mangazeisky Project is Sebyan-Kuel which is located approximately 50 km south. The village of Sangar, located 240 km southwest of the Project, is the administrative centre for the district of Kobyask Ulas within which lies the Mangazeisky Project.

Mineralisation and Geology

The Mangazeisky Exploration Licence area is located within the Verkhoyansk mobile belt of northeastern Yakutia. The fold-and-thrust belt forms part of a major orogenic system separating the Siberian North Asian Craton to the west from the immense expanse of accreted terrains, which form most of the Russian Far East.

The belt extends for 2,000 km from the Laptev Sea to the Sea of Okhotsk. The belt is made up of a rock package that is greater than seven km in thickness and is comprised of Late Precambrian to Triassic rocks deposited along the paleo‑Pacific margin of the Siberian Craton. This margin developed as a consequence of rifting events which occurred in the Late Precambrian and again during the Late Devonian to Early Mississippian periods. Deformation events during the Late Jurassic to Early Cretaceous periods were accompanied by low-grade metamorphism in the internal parts of the belt and the emplacement of high-level granitic bodies. During the Tertiary period, strike-slip faulting occurred within the fold-and-thrust belt. The central part of the belt is dominated by a thick monotonous succession of Carboniferous and Permian turbidites which are metamorphosed to lower greenschist grade. Granodiorite and granite plutons intrude the core of the range and are associated with extensive gold-bearing quartz vein systems.

The silver mineralization is epigenetic. To date, Mangazeisky host four types of mineralisation:

  1. Vertikalny deposit – narrow steep dipping veins that cross-cut stratigraphy, feature grades in excess of 1,000 g/t Ag over widths ranging up to 3 metres
  2. Mangazeisky N &S deposit – strata-bound silver-bearing, quartz-carbonate-sulphide structures with lead, zinc by products with grades greater than 900 g/t Ag
  3. Nizhny Endybal deposit – thicker linear-type stockwork with carbonate-silver sulphosalt mineralisation
  4. Porfirovy prospect – rhyolite porphyry area associated with quartz, quartz-carbonate and quartz-sulphide veining
