Giant plans for additional Majuba metallurgical testwork

The Announcement -A New Metallurgical Test Program

Giant Mining has announced that it will carry out additional metallurgical test work at Majuba Hill, aiming to update and expand on older, historical metallurgy studies done on the property.
This new program intends to more precisely assess how copper, silver, and gold recover across the oxide, transition and sulphide zones of the porphyry system — offering a more robust technical understanding than the older data.

What the Program Will Do - Domains & Processing Options

The metallurgical programme will test all mineralization domains — oxide, mixed (transition), and sulphide — to get a full picture of the deposit’s potential. It also plans to evaluate multiple processing routes: heap-leach, flotation, and/or vat-leaching, plus downstream circuits for silver and gold — to understand which method or combination yields the best recoveries for each metal.

Strong Drill History Evidence of High-Grade Copper & Silver

Historical drilling at Majuba Hill has shown compelling high-grade copper and silver intercepts. For example, drill hole MHB-30 reportedly returned 74.0 ft averaging 2.6% Cu and 30.1 g/t Ag — within a broader 218 ft averaging 1.35% Cu and 73.4 g/t Ag.
These results underscore that Majuba Hill is not just a low-grade bulk deposit, but has zones of significant grade — which makes metallurgical test-work especially valuable for unlocking full project potential.

Historical Metallurgy Encouraging but Preliminary

Earlier metallurgical testing (on historical drill and oxide samples) suggested that oxide material may be amenable to conventional heap-leach with copper recoveries up to ~81–85% under favourable conditions.
Flotation tests on sulphide/complex material returned silver recoveries in the range of ~44.5% to ~74.9% (depending on conditions), showing promise but leaving room for improvement especially for gold — which requires modern recovery methods that the new program intends to evaluate.
Because those older studies pre-date the company’s involvement and were done under older standards, they are treated as preliminary; the new metallurgical work aims to deliver more reliable, QA/QC-compliant data.

Strategic Timing — Metal Prices & Growing Demand

The timing of the new test-work comes when copper, silver, and gold have recently hit record or near-record prices — making the project’s economics potentially more attractive.
Given global push for critical metals (for energy transition, infrastructure, etc.), a robust, well-documented copper–silver–gold deposit at Majuba Hill could become increasingly valuable — making the test-work a strategic move.
