Tijirit (Au)

About Tijirit

The Tijirit Gold Project is located in northwestern Mauritania, 25 kilometers southeast of Kinross’ Tasiast Gold Mine. The project is an orogenic gold camp with development stage gold deposits within multiple pits. The 26-year mining permit consists of a single 150 square-kilometer area with significant exploration upside with multiple styles of structurally controlled gold mineralization and multiple untested structural targets. A feasibility study is scheduled for completion in 2024.

Feasibility Study

A feasibility study has been launched to assess the potential for developing Tijirit. The study envisages a base case scenario of a 1,000-tpd processing plant. The proposed initial flowsheet will comprise a conventional primary crush and SAG milling circuit, followed by gravity gold recovery and leaching.



2018 PEA


  • Pre-tax NPV of $94.9M and 28.4% IRR at an 8% discount rate a gold price of $1,250/oz
  • After-tax NPV of $69.0M at an 8% discount rate with an IRR of 23.5%
  • Production of over 580,000 ounces of gold over a +7-year mine life, at an All In Sustaining Cost (AISC) of $726/oz
  • Payback: 1.8 years (after-tax)
  • Potential for improved economics through increased resource definition



Technical reports

Technical Report for the Preliminary Economic Assessment of the Tijirit Project in Mauritania – March 9, 2018

Tijirit Project NI 43-101 Technical Report with Resource Estimate Update – January 19, 2018


The project is located in northwestern Mauritania, some 275 kilometers north of the capital Nouakchott, and 25 kilometers southeast of the Tasiast Gold Mine (+15 M oz Au).


Year-round access to the Tijirit project is assured from Nouakchott by a paved road that runs over 200 kilometers north. From there, a dirt road runs 105 kilometers northeast along the Akchar dune bar.

Surface area

The Tijirit mining permit covers 156 km².

Tijirit Location


Gold mineralization at Tijirit is structurally controlled concentrating along local faults and shear zones spatially associated with lithological contacts between iron formations, various metasedimentary sequences, and intermediate and mafic metavolcanic and meta-igneous rocks. Gold is locally visible, mostly as native hydrothermal grains within quartz carbonate veins, silicified zones within sheared metabasites, associated with sulphides in metasediments or within quartz veins and alteration halos proximal to meta-igneous rocks.

At present, multiple styles of gold mineralization have been identified at Tijirit, all of which are structurally controlled and are not constrained to BIF only. However, iron-rich lithologies such as BIF still likely played a vital role in gold-distribution at camp-scale.

The Eleonore zone is characterised by at least four en-échelon, high-grade gold deposits (Eleonore South, Central, North and East) elongated along a major NNE-structural corridor in which NE-SW splay appears to play an important role.



A 25,000-meter drill program has been completed on Tijirit that includes 3,000m of diamond drill infill and 22,000m of RC drilling. The infill program will be dedicated to converting inferred resources into measured and indicated resources for the Tijirit feasibility study. The exploration drilling will focus on expanding the mineral resources statement.
