PROJECT AND CLIENT FOCUSED METALLURGICAL SUPPORT

SERVICES

Toll Treatment Campaign Management and Client Representation

JT's aim: Maximise ounce output and account for every ounce in a transparent way to all parties.

Toll treatment allows mines that have limited starting capital and/or a small resource to expedite cash flow without the cash intensive and timely process of plant development and construction.

JT’s provides independent and unbiased management services to ensure maximum return to the Project by focusing on mine to mill and blending strategies, plant optimisation, comprehensive reporting and metallurgical accounting and gold reconciliation practices. 

JT’s is the chosen Client representative for a number of private and small-tier publicly listed gold companies and with a Perth and Kalgoorlie base, we are well placed to provide this service.

Test Work and
Process Design Studies

JT’s have developed and maintained professional relationships with many of the laboratories and engineering firms across Australia and South Africa. Each of these offer specialised expertise for differing aspects of metallurgical processing.

Whether it be baseline or comprehensive testwork programs, research and development, pilot scale testwork or full turn-key projects, JTMS will be able to identify the clients’ metallurgical needs and shift the focus into the most suitable direction.

Onsite Metallurgical Contracting

JT’s offers short term metallurgical contracting to cover leave or complete a specific project or task.

Process Plant Optimisation and Audits

JT’s is able to work with onsite personnel to identify, define and generate a plan in optimising a plant or metallurgical accounting processes by:

  • Ensuring a thorough understanding of how current and future mining practices and geological and mineralogical aspects of the ore impact the overall process;

  • Working systematically through each facet of the plant to identify bottlenecks or problematic equipment or areas;

  • Training Operators and Metallurgists in maximising the performance of the plant;

  • Identifying and championing testwork which may be required;

  • Conducting thorough metallurgical accounting audits.

 

ABOUT

JTMS is a small niche metallurgical consultancy formed by two experienced metallurgists, Brant Tapley and

Nicholas Johnson.

 

Both Brant and Nick have been extensively involved in design phases, operation, and optimisation on a number of plants, over a number of commodities worldwide.

Our aim is to be actively involved with our clients in aiding their metallurgical needs. We strive to deliver outcomes which are in the best interest of our clients, whether it be in project development, metallurgical testwork programs or management over single and ongoing toll treatment campaigns. 

 

We have particular focus on Mine to Mill through engaging the mining and geology team followed up by comprehensive yet appropriately sized testwork programs to ensure maximum Project return. 

 

JT’s considers reporting to be an important aspect in all facets of what we do hence focus is applied to this to keep the Client completely up to date and to have the opportunity of being part of the solution.
