Name of the Project
Twin Hills gold project.

Location
Namibia’s prospective Damara sedimentary mineral belt, between the towns of Omaruru and Karibib, in the Erongo region.

Project Owner/s
Dundee Precious Metals (DPM) entered into a definitive agreement to acquire TSX-V-listed Osino Resources Corp and, in turn, Osino's high-quality, long-life Twin Hills openpit gold project, along with other exploration assets, in December 2023.

Project Description
A definitive feasibility study (DFS) has proposed the development of a low-risk, technically simple openpit mine using contract mining.

Life-of-mine (LoM) gold recovery is estimated at 92% using three-stage crushing, ball milling, gravity separation, pre-oxidation and carbon-in-leach plus filtration, and dry-stack tailings deposition.

The carbon-in-leach metallurgical plant will process five-million tonnes a year of mineralised material over a 13-year LoM.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 5% discount rate, of $742-million and an internal rate of return of 34%, with a payback of 2.2 years.

Capital Expenditure
The initial capital cost of the project is estimated at $365-million.

Planned Start/End Date
Initial gold production is expected in 2026.

Latest Developments
Dundee intends to advance all remaining engineering activities for Twins Hills to reach a construction decision by the third quarter of 2024.

Over this period, the company plans to pursue opportunities to refine and optimise the mining, construction and execution aspects of the project, given DPM’s experience in the development and operation of its existing portfolio.

In parallel, DPM will also be reviewing the construction timeline, which is currently targeting first production in the second half of 2026.
