Name of the Project
Cascabel copper/gold/silver project.

Location
Northern Ecuador.

Project Owner/s
Exploraciones Novomining, an 85%-owned subsidiary of SolGold.

Project Description
A prefeasibility study (PFS) has concluded that Cascabel has the potential to be a large, low-cost and long-life mining operation based on achievable, proven and tested mining and processing assumptions.

The mine is expected to produce a clean copper/gold/silver concentrate, to be sold to Asian and European smelters as part of a project construction financing package.

The project has an initial mineral reserve of 558-million tonnes containing 3.3-million tonnes of copper grading 0.58%, 9.4-million ounces of gold grading 0.52 g/t, and 30-million ounces of silver grading 1.65 g/t over an initial 26-year life-of-mine (LoM), with a potential LoM upside of more than 50 years following the initial LoM.

Access to the Alpala underground mine is expected to be through twin declines,  starting from a boxcut near the surface and the first lift near the 300mRL. Block cave mining will be applied to the underground resource while all horizontal development will be undertaken using conventional drill-and-blast methods. The vertical development for the main ventilation rises will be excavated using blind sinking methods.

The crushed ore from the underground primary crushers will be conveyed to the surface and fed to the secondary crushing circuit. The product from the secondary crushing area will be transferred to the fine ore stockpile, and subsequently reclaimed to the high-pressure grinding rolls (HPGR) circuit.

The product from the HPGR circuit will be transferred to a grinding circuit comprising ball mills that operate in closed circuit with a hydrocyclone cluster.

The project is initially expected to produce about 132 000 t/y of copper, 358 000 oz/y of gold and one-million ounces of silver (212 000 t/y copper equivalent), with peak copper production of 210 000 t/y (319 000 t/y copper equivalent).

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has an estimated pretax net present value, at an 8% discount rate, of $5.2-billion and an internal rate of return of 25.3%, with a payback of 4.7 years from the start of operations.

Capital Expenditure
$2.7-billion for the initial cave development, first process plant module and infrastructure.

Planned Start/End Date
Construction of the mine is expected to start in 2025, with operations starting in 2030.

Latest Developments
SolGold has announced that it has completed the contractual negotiations and agreed upon a term sheet with the government of Ecuador in preparation for the execution of the exploitation agreement for the Cascabel project.

The agreement, together with existing legislations and regulations, establishes the legal and financial terms and conditions required for the project's development.

In the following months, SolGold must apply to change the Cascabel's official status from exploration phase to exploitation phase. The company has up to six months after the approval of the Phase Change Application to execute the Exploitation Agreement with the Government of Ecuador.
