  • The thickener mechanical installation has been completed and painting is now in progress, while the electrical installation is over 80% complete in this area.
  • Direction testing of all drives is ongoing in the plant area with 80% of the spillage pumps and all thickener underflow pumps checked and ready to start.
  • Piping and electrical wiring in the CIL, elution, milling and detox circuits are currently underway.
  • The oxygen plant area and gold room are in an advanced state of preparation.
  • Work on the Tailings Storage Facility ("TSF") is progressing to schedule with current storage capacity sufficient for the first 15 months of processing operations.

Other highlights include:

  • The Komatsu PC2000 excavator was commissioned during March and is now working in the Larjor pit.
  • Mining activities are advancing well and have focused on the weathered eastern and western ends of the Larjor pit, where mining levels are being mined down to the 65 RL elevation.
  • Mining has also commenced in the weathered zone of the Kinjor starter pit, with the first flitch on the 67.5 to 65 RL elevation of the Kinjor starter pit now completed.
  • All mined oxide material has now been stockpiled ready for processing.
  • Grade Control drilling has shown excellent reconciliation with the resource model, confirming the robust nature of the orebody.
  • The flood bund around the Larjor pit has been completed ahead of the wet season, protecting the mining pit from water ingress during the approaching wet season.
  • Work is continuing to progress on the sumps and water diversion bunds within the pit ahead of the wet season.
  • The MonuRent supplied mining equipment training simulators have been installed and commissioned to increase operator efficiency and allow for the safe training of new Liberian equipment operators.

Health & Safety

  • No lost time injuries ("LTIs") have been recorded on site during 2015, which brings the total LTI free hours to 1,015,605. It has been 168 days since the last LTI on site.

Ebola

Significant progress has been made by the Republic of Liberia during 2015 in the fight against Ebola, with Liberia now close to being declared Ebola free.  After a period of over three weeks without a confirmed case of Ebola in the country, there was a single confirmed case reported in the Monrovia area in the week ending 22 March.  However since this time there has been a further two weeks with no new confirmed cases reported, and as at 5 April 2015 no other counties within Liberia have reported a confirmed case within the past 42 days.  There have also been no confirmed cases of Ebola in the counties within Guinea and Sierra Leone adjacent to the Liberian borders in more than 42 days.

About Aureus Mining Inc.

The Company's assets include the New Liberty gold deposit in Liberia (the "New Liberty Gold Project," "New Liberty" or the "Project"), which has an estimated proven and probable mineral reserve of 8.5 Mt with 924,000 ounces of gold grading 3.4 g/t and an estimated measured and indicated mineral resource of 9,796 Kt with 1,143,000 ounces of gold grading 3.63 g/t and an estimated inferred mineral resource of 5,730 Kt with 593,000 ounces of gold grading 3.2 g/t. A Definitive Feasibility Study ("DFS") has been completed on the Project and construction is well progressed. The Project is expected to have an 8 year mine life and annual production of 119,000 ounces for the first 6 years of production. The Company has financed the Project's equity and debt funding requirement. The foregoing mineral reserve and mineral resource estimates and additional information in connection therewith are set out in the Company's technical report dated March 25, 2015 and entitled "New Liberty Gold Project, Bea Mountain Mining Licence Southern Block, Liberia, West Africa, Definitive Project Plan."

The New Liberty Gold Project is located within the Southern Block of the 100% owned Bea Mountain mining licence.

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.
