6 terms

annualized production rate technical

"targeting an annualized production rate of approximately 500,000"

gold equivalent ounces technical

"approximately 500,000 gold equivalent ounces"

Gold equivalent ounces express the combined output or reserves of a mine by converting other metals (like silver, copper or zinc) into the amount of gold they would be worth at current market prices, so everything is shown as a single “gold” number. For investors this provides a common yardstick to compare production, value and growth across projects that produce multiple metals—like converting several currencies into one familiar money unit.

feasibility-stage technical

"the feasibility-stage Diamba Sud Gold Project in Senegal"

Feasibility-stage is the early phase when a project, clinical study, or business idea is being tested to see if it can work in practice, covering technical, regulatory, and financial questions. For investors, this stage matters because it signals high uncertainty and risk but also the chance for large upside if key hurdles are cleared—think of it like a prototype test drive that determines whether a full launch is worth the bigger investment.

final investment decision technical

"subject to a positive final investment decision"

A final investment decision is the point at which a person or organization chooses to move forward with a particular project or purchase after reviewing all the necessary information and options. It is like deciding to buy a house after considering all the costs, benefits, and alternatives. This decision is important because it determines whether and when the investment will be made, impacting future financial plans and outcomes.

Mineral Resource estimates technical

"current Mineral Resource and Mineral Reserve estimates"

Mineral resource estimates are scientific calculations of how much of a particular metal or mineral likely exists in a specific underground deposit, expressed in quantities and quality based on drilling, sampling and geological models. Investors use them like a preliminary inventory or treasure map: they indicate potential value and help size exploration and development decisions, but they are not guaranteed marketable reserves and usually require further work to confirm economic viability.
