Name of the Project
Twin Hills gold project.

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.

On February 19, 2024, Osino announced that it had received a proposal from a foreign-based mining company, Yintai Gold, for the acquisition of all the issued and outstanding common shares of the company, as well as all the issued and outstanding securities convertible into common shares for a cash consideration of C$1.90 for each common share through a plan of arrangement.

Osino’s board of directors unanimously determined, after consultation with its financial and legal advisers, and based upon the unanimous recommendation of the special committee of the board, that the new offer constituted a "superior proposal" in accordance with the terms of the DPM Arrangement Agreement between Osino and DPM.

DPM chose not to amend the terms of the DPM Arrangement Agreement in light of the superior proposal.

On February 25, 2024, Osino and Yimtai announced that that they had entered into a binding arrangement – the Yintai Arrangement Agreement – pursuant to which Yintai will acquire all the outstanding common shares of Osino. At the closing of the agreement, Osino’s portfolio will comprise only gold-related assets in Namibia, primarily the Twin Hills gold project, and the exploration projects Ondundu and Eureka.

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
None stated.
