NEW LIBERTY GOLD MINE: OPERATIONAL UPDATE
Aureus Mining Inc., (“Aureus” or the “Company”), the TSX and AIM listed West African Gold Producer, provides the following operational update for the New Liberty Gold Mine (“New Liberty” or “Mine”) in Liberia.
- Comminution circuit (consisting of the primary and secondary crushers and ball mill) now operating at design throughput capacity;
- Ongoing optimisation programme to focus on improving the performance of the gravity and Carbon in Leach (“CIL”) circuits to achieve production performance in accordance with design specifications;
- Issues experienced during the final phase of commissioning in the gravity and CIL circuits have affected plant recoveries resulting in reduced gold sales;
- Gold production achieved during 2015 was 17,172 ounces, against a target of 27,000 ounces, and 3,663 ounces of gold have been produced to date in 2016;
- The Company has entered into discussions with its banks to obtain a deferral of the first bullet repayment, scheduled for 31 January 2016.
Operations Update and Commercial Production
Since the resumption of processing operations at New Liberty on 30 October 2015, over the last 81 days the ball mill has been operating at an average of 82% of its designed capacity, including planned downtime for ongoing optimisation. The criteria for the declaration of Commercial Production, which has previously been communicated to the market, has been reached, however, Aureus has experienced issues during the final phase of commissioning in the gravity and CIL circuits of the plant, affecting plant recoveries and resulting in an impact on cash flow and therefore does not feel it is prudent to officially declare commercial production at this point.
The Company continues to focus on fine-tuning and improving the operational performance of the gravity circuit and further optimising CIL leach kinetics, with various options being evaluated and systematically implemented in order to improve overall plant performance to within design specifications.
It is anticipated that plant performance will improve to design levels by the end of Q1 2016, when the Company intends to declare full commercial production at New Liberty once the entire process plant is operating at full design capacity and in a manner consistent with management expectations.
Mining operations at New Liberty are progressing, with fresh ore run of mine (“ROM”) stockpiles currently standing at 83,509 tonnes at a grade of 2.78 g/t and oxide and transitional stockpiles of 75,248 tonnes at a grade of 1.35 g/t. To date, the New Liberty process plant has processed 386,262 tonnes of ROM fresh sulphide ore and lower grade oxide material resulting in 19 shipments of gold doré from New Liberty for smelting and refining at the MKS PAMP refinery in Switzerland, totalling 20,835 ounces of gold. The average achieved price for gold sold is US$ 1,113 per ounce.
Gold production achieved for the calendar year 2015 was 17,172 ounces, against a target of 27,000 ounces, and 3,663 ounces of gold have been produced to date in 2016, with production since mid-December hampered by issues experienced during the final phases of plant commissioning. Performance from the gravity circuit of the plant has not yet reached design specifications, resulting in overall gold recoveries of approximately 70% throughout December 2015 and early January 2016. The Company has implemented various initiatives to address these issues – there has recently been a subsequent improvement in the performance of the CIL circuit, with further improvements expected over the coming weeks.
Updated Mine Plan
Several Life of Mine (“LoM”) options for New Liberty are currently being evaluated by the Company to align production to the current gold price environment. It is anticipated that this review process will be completed by the end of February 2016, upon which time further updates will be communicated.
Bank Debt Repayment Being Rescheduled
Following discussions with FirstRand Bank Limited, acting through its Rand Merchant Bank division (“RMB”), Nedbank Limited (“Nedbank”) and the Export Credit Insurance Corporation of South Africa Limited (“ECIC”), (collectively, the “Lenders”), who are progressing through their credit approval process to obtain approval for a deferral of the first debt repayment (which is scheduled for 31 January 2016) and thereafter will work with the Company to agree upon an appropriate debt repayment schedule in conjunction with the Updated Mine Plan.
The Company has sought Lenders approval for deferral of the first debt repayment as it currently has insufficient cash resources available to pay both the first debt repayment and continue to make payments to suppliers as they fall due. It is anticipated that revenue generated from future gold production should ensure that suppliers continue to be paid and operations can continue at New Liberty.
Appointment of Financial Advisor
Aureus is finalising the appointment of a Financial Advisor to conduct a strategic review to assess potential options that may be available to Aureus.
Commenting, David Reading, President and Chief Executive Officer of Aureus Mining, said:
“The commissioning phase of New Liberty has brought some unexpected challenges, however, the recent progress being made and improved performance of the process plant are encouraging. I am confident that the various process improvements that our experienced operations team are systematically implementing will continue to improve the overall plant performance towards design specifications.
“We look forward to receiving the final approvals from Nedbank, RMB and the ECIC and would like to thank them for their continuing support and we look forward to agreeing a new repayment schedule in due course.”

Readers are cautioned not to place undue reliance on forward-looking information as actual results could differ materially from the plans, expectations, estimates or intentions expressed in the forward-looking information. Forward-looking information speaks only as of the date on which it is made and, except as may be required by applicable law, Aureus disclaims any obligation to update or modify such forward-looking information, either as a result of new information, future events or for any other reason.
With respect to forward looking information contained in this news release, assumptions have been made regarding, among other things: general business, economic and mining industry conditions; interest rates and foreign exchange rates; mineral resource and mineral reserve estimates; geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral resources and mineral reserves) and cost estimates on which the mineral resource and mineral reserve estimates are based; the parameters and assumptions employed in the New Liberty Technical Report, (including but not limited to, those relating to construction, future mining and operating costs, processing and recovery rates, net present values and internal rates of return, timing for the commencement of production, tax and royalty rates, future gold prices, metallurgical rates, pit design, operations and management, grades, the base case analysis and the proposed budget for further exploration plans and objectives); the supply and demand for commodities and precious and base metals and the level and volatility of the prices of gold; market competition; the ability of the Company to raise sufficient funds from capital markets and/or debt to meet its future obligations and planned activities; the business of the Company including the continued exploration of its properties; the political environments and legal and regulatory frameworks in Liberia and Cameroon with respect to, among other things, the ability of the Company to obtain, maintain, renew and/or extend required permits, licences, authorizations and/or approvals from the appropriate regulatory authorities and the ability of the Company to continue to obtain qualified staff and equipment in a timely and cost-efficient manner to meet its demand. Assumptions used in the preparation of such information, although considered reasonable by Aureus at the time of preparation, may prove to be incorrect.
Any mineral resource and mineral reserve figures referred to in this press release are estimates and no assurances can be given that the indicated levels of minerals will be produced. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. While the Company believes that the mineral resource and mineral reserve estimates in respect of its properties are well established, by their nature mineral resource and mineral reserve estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable. If such mineral resource and mineral reserve estimates are inaccurate or are reduced in the future, this could have a material adverse impact on the Company. Due to the uncertainty that may be attached to inferred mineral resources, it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
