- Auralia Mining Consulting complete initial Scoping Study at FGP, showing encouraging results.
- Existing Mineral Resources all open pit, free milling gold with high gravity gold recovery.
- Existing ~216K ounce Mineral Resource (Indicated & Inferred), reported in compliance with JORC (2012), with strong exploration upside.
- Open pit mining in 2002 - 2003 produced 95,865 tonnes @ 8.81g/t for 27,146 oz Au.
- Targeting low capital costs via processing through local toll treatment facilities.
- Classic to move onto PFS and exploration drilling in the near future.
The estimated Mineral Resources underpinning the Study have been prepared by a Competent Person in accordance with the requirements in the JORC Code (2012). Classic's study was completed with assistance from the following reputable industry consultant groups; Auralia Mining Pty Ltd (mine design, financial modelling); Entech Pty Ltd (resource review and mining); Australian Resource Consulting Pty Ltd (historical data compilation and review; exploration planning); Martinick Bosch Sell Pty Ltd (MBS Environmental) (baseline environmental, heritage); and Rockwater Pty Ltd (groundwater).
The results of the Study were positive and importantly provide strong encouragement for the Company to commit to the next stage of its exploration and development program.
Managing Director Mr Justin Doutch stated:
"Classic decided to accelerate the due diligence process and its own understanding of the FGP Project by engaging experts to assist with a Scoping Study concerning development and mining of the FGP. The results were encouraging and a clearer pathway to development and feasibility work has been mapped out. Classic aims to complete the acquisition of the FGP in the near-term and does not foresee any major issues or reasons as to why shareholders would vote against the proposed transaction. In the meantime, Classic will continue its planning and technical work so that it can hit the ground running as soon as the transaction completes. We see great potential at the FGP for increasing the Resource and rapid mine development leading to Classic becoming a gold producer in the near-term. We are also excited to be partnered with Hannans Ltd who are in turn, supported by major shareholders Neo Metals and Australian Contract Mining - I am sure there are synergies to be explored as we move closer to mining."
The Mineral Resource was first reported in the announcement of 1 March 2017 and following corrected announcement on 14 March 2017. The Scoping Study was based on both Inferred and Indicated Resources, with Inferred Resources making up 56% of the total tonnes and 63% of total ounces of the Mineral Resource. Because the Inferred Resources make up a fair proportion of the early phases of the proposed mining schedule, the level of confidence that Classic has with regards to the production targets and cash flow is insufficient for those targets to be publicly reported.
In addition, 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 determination of Indicated Mineral Resources or that the production target itself will be realised.
Auralia Mining Consulting Pty Ltd ("Auralia"), were engaged by Classic to carry out a Scoping Study on its FGP project, producing a high-level indicative mining and processing schedule utilising Whittle shells, inclusive of a high-level financial analysis. Given the level of study, and that Inferred Resources was used as an economic driver, no Ore Reserves can be reported from this Study.
The FGP consists of existing Mineral Resources of 4.8Mt at 1.3g/t for 216,000oz of gold Inferred and Indicated categories). Resources are located directly beneath an existing open pit and within un-mined, near-surface deposits. The Project presents an opportunity for near-term mining operations and production. The Scoping Study was designed to focus on open pit development and processing of the two gold Resources at Lady Ada and Lady Magdalene. The Study supports Classic's aim to complete a Preliminary Feasibility Study and apply for regulatory consents in 2017, with development targeted in 2017/2018.
Discussions with potential toll treatment facilities and contract miners are underway, with Classic expecting to firm up its development schedule and processing options over the coming weeks. There are numerous potential toll treatment facilities within trucking distance including Marvel Loch, Edna May, Greenfields (Coolgardie) and Norseman Gold.
Scheduling and Open Pit Operations
The Mineral Resource estimate and digital block models provided to Auralia by Classic were completed for the previous owner of the Project in March 2016 and were classified and reported in accordance with the JORC Code (2012). A dominant part of the Resources within the two deposits was classified as Inferred Mineral Resources.
Optimisations were undertaken by Entech with the results (data outputs and optimised pit shells) provided to Auralia. The data provided to Auralia was assumed to be complete and without omission, the inputs were reviewed by Auralia to assess their validity.
Mining operations for the Project are envisaged to utilise a standard truck and shovel configuration using a 100t Excavator (Komatsu PC1250 or similar) paired with 90t rigid body dump trucks (Cat 777 or similar). Ramp parameters used throughout the pit designs could allow single-lane traffic flow with passing bays located at each berm (every 10 or 20m vertically).
Specific waste dumps and ROM pads have not been studied at this stage, it is envisioned that the existing waste dump from the Blue Haze operation will be expanded to hold the Lady Ada waste, while a new waste dump will be constructed for the Lady Magdalene pit.
The Lady Magdalene proto pit was determined to likely have comparatively low "pre-strip" requirements, and could be the first focus of mining operations, to access sufficient material to meet the required processing throughput. There would be a five-month pre-strip period during which time only small parcels of material would be scheduled for mining. The delay in processing would allow the estimated throughput rate to be achieved from first material delivery. After a relatively short period from the start of the mining operations, there could be sufficient material available to allow production to commence in the Lady Magdalene 2 pit, and subsequently the Lady Ada pit. With production split between the Lady Magdalene 1 pit and the two other higher strip ratio pits, mining targets could potentially be achieved at a fairly constant strip ratio.
Comments and Next Steps for Classic at FGP
The immediate focus now is to undertake exploration and drilling programs, to increase confidence in the existing models, and to expand the Mineral Resources by unlocking the significant upside potential of the known Lady Magdalene and Lady Ada deposits, which are both open at depth. Other regional gold targets, generated through review and reinterpretation of existing mag data and auger/soil sampling data will also be tested. This work is scheduled to commence shortly and is aimed at delivering an updated Mineral Resource in Q1 2018.
The updated Mineral Resource is planned to feed into a Pre-Feasibility Study which will be commenced shortly and is due to be completed in Q2 2018. The Pre-Feasibility Study will aim to establish Mineral Reserves, classified and reported in compliance with the JORC Code (2012), and optimise the mining schedule, production rate and process flow sheet while reducing capital and operating costs. It will also go into greater detail in respect of processing options and costs and environmental factors.
Classic will also aim to release a more detailed summary of the Scoping Study outcomes, including economic/production outcomes over the coming 2 weeks.
The exploration program over the next 12 months will include:
- Infill and extension drilling to upgrade the Lady Ada and Lady Magdalene Resource area;
- Comprehensive metallurgical test work to optimise plant design;
- Exploration drilling of gravity targets;
- Additional environmental flora and fauna surveys (if required), and characterisation of waste and tailings material required for development approval; and
- Structural geology to interpret the regional structure and its controls on mineralisation.
- Geotechnical and hydrogeological studies and testwork.
