Tunkillia Scoping Study Presentation - Seite 2
Basis of Study (Key Geological and Cost Estimation Factors)
This announcement has been prepared in compliance with the JORC Code 2012 Edition (JORC) and the ASX Listing Rules. All material assumptions on which the forecast financial information is based have been provided in this announcement and are also outlined in the annexed JORC table disclosures.
The capital cost estimate for the process plant and associated infrastructure has been prepared by GR Engineering Services Limited with a nominal accuracy of ±35%, with mining costs estimated by Mining Associates Pty Ltd at a scoping study level of accuracy from first principles on a bench-by-bench basis.
Production is based on Tunkillia's JORC Mineral Resources Estimate (MRE). The JORC MRE underpinning the production target have been prepared by a competent person in accordance with JORC, with ~66% of materials classified ‘Indicated' and ~34% ‘Inferred'. There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised.
~74% of the JORC Mineral Resources scheduled during the first five (5) years of the production target are classified as Indicated. Given a projected 1.9 year payback period (from start of production), Barton considers that Tunkillia's financial viability does not depend upon inclusion of Inferred Resources, and therefore that a reasonable basis exists for disclosing a production target including Inferred Resources.
Funding Requirements
The Scoping Study is based on the material assumptions outlined in this announcement. These include assumptions about the availability of funding. Barton's leadership has a strong track record of raising funding as required on attractive terms, and a significant combined professional track record in the and development of resources projects. However, while Barton considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the Scoping Study will be achieved.
