Northern Graphite Announces Metallurgical Test Program
October 29, 2018 (Source) — Northern Graphite Corporation (TSXV: NGC) (OTCQX: NGPHF) (the “Company”) announces that SGS Canada Inc. (“SGS”) has initiated a comprehensive metallurgical test program on ore from the Company’s Bissett Creek project to confirm the results of previous studies which identified a number of promising opportunities to reduce capital and operating costs and further improve project economics. This work must now be brought up to the standards required in a full feasibility study. The metallurgical program is expected to take approximately 16 weeks and is part of a high-level review of project economics being undertaken by G Mining Services Inc. prior to updating the Company’s feasibility study.
Gregory Bowes, CEO, commented that: “The Bissett Creek project already has solid economics at current prices because of a reasonable capital cost and production that will be almost entirely high value, large/XL/XXL flake concentrate.” He added that: “Our strategy is to develop a project that has a realistic production level relative to the size of the market, focusses on high margin, low risk markets and provides a reliable, secure source of western supply for customers.”
Test work previously carried out over the last year by SGS and/or BGRIMM, a premier Chinese institute in the field of mining and metallurgical technology, have identified a number of opportunities to potentially improve the economics of the Bissett Creek project. These include:
- Grinding the ore fine enough in the SAG mill so that it can be sent directly to flotation without having to go through regrinding and rougher flotation. This would result in the removal of a large ball mill and one flotation circuit from the flow sheet which will reduce capital costs by approximately CDN$5 million and also reduce operating costs.
- Increasing the yield of large/XL/XXL flakes (+80/+50/+35 mesh) in the overall concentrate to 93 per cent (with 73 per cent being XL/XXL) which is believed to be the highest in the industry.
- Increasing the average concentrate purity from 94.5 to 97 or 98 per cent through the addition of a small stirred media mill. This technology was not available at the time of the original feasibility study.
- Removing a small sulphide regrind and cleaner circuit from the flow sheet saving both capital and operating costs. The process includes a sulphide flotation step which removes enough sulphides from the tailings to render 97 per cent of them non-acid generating. The resultant sulphide concentrate will now be sent directly to a special tailings facility without further processing.
The SGS test program will include standard comminution tests including SMC, ball mill grindability and abrasion testing, an assessment of single stage grinding, flotation and polishing grind optimization, and the evaluation of a stirred media mill versus a polishing mill. A number of locked cycle tests will be carried out to mimic continuous operation and the fully optimized conditions will be tested on nine variability composite samples. Over 120 drill holes were included in the composites to ensure good spatial representation throughout the deposit and representation from different periods during the mine life.
About Northern Graphite
Northern Graphite is a Canadian development company with a 100% interest in the Bissett Creek graphite deposit which is located in southern Canada, relatively close to all required infrastructure. The Company has completed a full FS, a PEA which includes a Phase 2 expansion, and has secured its major mining permit. The Bissett Creek Project has a relatively low initial capital cost, a high profit margin and low marketing risk resulting from its extremely good flake size distribution, and a realistic production level that can easily be expanded when market conditions warrant.
