Name of the Project
Star-Orion South diamond project.

Location
The project is situated in the Fort à la Corne diamond district of central Saskatchewan, Canada.

Project Owner/s
Star Diamond Corp.

Project Description
A preliminary economic assessment (PEA) has determined that an estimated 66-million carats of diamonds could be recovered from a surface mine over a 34-year life-of-mine.

The PEA envisages the development of two openpits, initially Orion South, followed by Star, using conventional openpit methods.

Conventional hydraulic excavators and haul trucks create a starting “key” for three bucket wheel excavators to remove the sand and clay overburden from the kimberlite. Conveyor belts will transfer the sand and clay from the excavators to the nearby overburden waste area. The exposed kimberlite will be lightly blasted and conventional hydraulic shovels will load the rock into trucks. These trucks will transfer the rock to an in-pit feeder and the kimberlite will be delivered to the processing plant using a conveyor belt.

The processing facility will have the capacity to process 45 000 t/d of kimberlite using autogenous milling, followed by screening, X-ray transmission diamond recovery and dense-media separation of heavy mineral concentrate.

The recovery section will use X-ray technology, with grease as the scavenging technology to recover the low-luminescence diamonds. The diamonds will be sorted into parcels in the on-site sorting facility.

Potential Job Creation
Not stated.

All-in Sustaining Costs/All-in Costs
Not stated.

Net Present Value/Internal Rate of Return
The project has an after-tax net present value, at a 7% discount rate, of $2-billion and an internal rate of return of 19%, with a payback of 3.5 years after the start of construction.

Capital Expenditure
Preproduction capital expenditure is estimated $1.41-billion.

Planned Start /End Date
Not stated.

Latest Developments
Star Diamond has started legal proceedings against Rio Tinto Exploration Canada (RTEC) to protect its interest in the Star-Orion South project.

Star Diamond last month flagged possible legal action over RTEC’s purported exercise in November 2019 of its four options under the option and joint venture agreement of June 2017, claiming that it did not comply with the terms of the agreement.

Exercising the four options would give RTEC a 60% interest in the Star-Orion project.

Key Contracts and Suppliers
SGS Canada, DRA Americas and ENGCOMP Engineering and Computing Professionals (PEA).
