Sustainable Mining Practices for Environmental Conservation.

Responsible mining with sustainable practices, including rehabilitation, metallurgical tests, and reduced environmental impact.

The wider strategy for Transition’s copper focus is to define sufficient resources to support development of a mining and/or production hub, that would be centrally located to any identified deposits, or group of deposits, within the Duck Creek Copper Project, (DCCP).

Transition’s DCCP includes over 200 high-priority targets. Twenty prospects have been drill-tested in total and require follow-up drilling. Six prospects were included in the July 2023 MRE, including Meteor, New Dollar, Cleopatra, Scorpion, Pioneer and Mountain Maid. Preliminary pit optimisation is shown for each. Also shown are prosects (cross-picks) and important zones of mapped surface mineralisation (light red).

July 2023 Mineral Resource Estimate (MRE)

Total Indicated and Inferred resources of:
5.44 million tonnes @ 1.45% Cu, 0.11 g/t Au
Containing 78,734 tonnes of copper and 19,631 ounces of gold.

Test-Work on Mineral Waste

Transition conducted preliminary test-work on 8 mineralised waste samples to measure their suitability for third-party processing via heap leach.

Costs would be recovered by upgrading the mineralised waste piles to a saleable end-product specification, with options for buyers including local, interstate, and overseas parties. The program would result in the rehabilitation of hundreds of contaminated and dangerous sites, local jobs and stimulus, excess revenue to Transition, and royalties to the State.

Copper Recovery Test Successful for Transition

The samples had an average grade of 1.97% Cu, and the grades matched the visual estimate from Transition’s geologists. The samples underwent crushing, pulverising, and assaying, and achieved an average copper recovery of 75% with an acceptable acid consumption of 45.67kg acid/t ore. Transition plans to undertake an expanded program across many more stockpiles based on these pleasing results.

WHY CHOOSE TRANSITION

Hub & Spoke Mining

The DCCP presents near-term production opportunities and includes important existing infrastructure such as sealed roads (currently used by haul trucks), and state rail (Mt Isa to Townsville) traversing within 2km of the proposed development area. The DCCP is within trucking distance of four operating copper concentrators (for ore deliveries), and the Mt Isa smelter (for concentrate deliveries). 

Waste Retrieval

The Company plans to retrieve mineralised waste from historical dumps within ML90088 and surrounding areas to produce a saleable copper ore end-product through mechanical methods.

Sustainability

The Queensland Government’s proposed new CopperString 2.0 mains power grid passes approximately 12km east of the planned development area, providing options for lower-cost energy solutions. Cloncurry provides an excellent support hub with a local and FIFO workforce and all modern ammenities.

Ore Retrieval & 
Rehabilitation Strategy

Transition plans to retrieve historical mineralised waste piles from various sites throughout its tenements and implement a three-phase plan for their retrieval, sale, and rehabilitation. The waste piles will be crushed and upgraded at ML90088 using cyclones or similar methods to produce medium or high-grade saleable ore.

Ongoing 
Production

Transition plans for small-scale mining and ore upgrading to extend operations and benefit community and environment

Ongoing Production

Transition plans to focus on identifying additional ore from existing mining licenses if the mineralized waste upgrading and ore-sales operation proceeds as planned. The company also intends to continue searching for suitable shallow oxide deposits for potential small-scale mining operations.

Exploration with a mind to production

All exploration methods incorporate best practices for eventual transformation of exploration data into JORC 2012 compliant  Mineral Resource Estimates and viable mine planning.

Upgrading Third-Party Ore

Transition may also look to upgrading third-party ore that would be delivered to ML90088 from surrounding areas. This ore would be predominately, if not entirely, of similar characteristics to ore from the original Chinaman Mine that now dominates the surface profile of ML90088.

“Costs would be recovered by upgrading the mineralised waste piles to a saleable end-product specification.”

Improved Environmental Amenity and Net Reduction

It is anticipated the operations at ML90088 (including upgrading of third-party ore), would result in improved environmental amenity and a net reduction of the current area of disturbance at ML90088.
