Aureus Mining Inc. (TSX: AUE / AIM: AUE) (“Aureus” or the “Company”) is pleased to announce that it has entered into an Agency Agreement and a Subscription agreement (each as defined below) in connection with the issue of 56,000,000 new common shares of the Company (“Shares”) for proceeds of approximately £10.1 million (approximately US$15.3 million) before expenses.

The Company has entered into an agency agreement (the “Agency Agreement”) with GMP Securities Europe LLP. and Numis Securities Limited (together the “Bookrunners”) and Edgecrest Capital Corporation (collectively the “Agents”), pursuant to which, subject to the conditions referred to therein, the Agents have agreed, on a reasonable endeavours basis, to procure purchasers for 26,760,234 new common shares of the Company (“Shares”) at a price of 18p per Share (the “Issue Price”) to raise gross proceeds of approximately US$7.3 million (approximately £4.8 million) (the “Offering”).

In addition to the Offering, Aureus is pleased to announce that it has entered into a subscription agreement with International Finance Corporation (“IFC”), the private sector arm of the World Bank Group, for a subscription, subject to the conditions therein referred to, of 29,239,766 Shares at the Issue Price to raise gross proceeds of approximately US$ 8.0 million (the “Subscription”).

The funds raised by the Offering and the Subscription will be used to fund a new mine plan at New Liberty, which should allow for increased flexibility and generate stronger cash flows, particularly in the early years of the Project’s production phase.

David Reading, President and Chief Executive Officer of Aureus Mining, said:

“The funds to be raised through the Offering and the Subscription will allow the Company to push forward with the new optimised mining plan, which is more in line with the current gold price environment and achieves significant additional and accretive benefits to all our shareholders and stakeholders through earlier cash flow generation, a lower cost profile and improved operational efficiencies. We would like to thank both our existing and new shareholders for their support in bringing New Liberty into full production.

“Despite the challenges posed by the Ebola outbreak, our construction and operations teams have worked tirelessly to continue the development of the New Liberty Project. The completion of the first blast represents a major milestone towards the first gold pour of the first commercial gold mine in Liberia.”

Impact of Ebola Crisis

The Ebola outbreak has had a significant effect on the Republic of Liberia with 8,700 Ebola-related cases and in excess of 3,600 deaths. Recently, considerable progress has been made in the fight against Ebola with the Republic of Liberia seeing a substantial decline in the number of new cases – only five new confirmed cases were reported in Liberia in the week to 1 February 2015, down from a peak of 300 new cases per week during August and September 2014.

While Aureus maintained construction activities throughout the peak of the Ebola crisis, first gold pour has been delayed from March 2015 to the end of May 2015 as a result of logistical and other difficulties beyond the Company’s control, with steady state production now scheduled for July 2015.

Whilst Aureus implemented stringent health protocols and procedures to ensure that construction activities could continue, the Ebola outbreak has resulted in:

  • Direct additional costs of approximately US$ 6 million;
  • Indirect additional costs associated with the delay and contractual commitments of approximately US$ 10 million at the project level; and
  • Indirect additional non-project costs of approximately US$ 2 million at Company level.

Hence, the Company estimates its total additional direct and indirect costs related to Ebola to be approximately US$ 18 million.

However, despite the delay to the construction schedule and the increased costs introduced by the difficulties of operating throughout the Ebola outbreak, the Company remained fully funded to complete the New Liberty plant construction and reach nameplate production capacity with its available cash resources and finance facilities prior to this announcement.

New Mining Plan Optimises Returns and Provides Greater Operational Flexibility

The Company remains funded for its current development plan as set out in the definitive feasibility study titled “New Liberty Gold Project, Liberia, West Africa Updated Technical Report” dated July 3, 2013 (“DFS”), which may be found under the Company’s profile at SEDAR.com. However, when taking into account the delay to the commencement of processing operations, the DFS does not optimise returns in the current gold price environment.

Since the DFS was completed in 2013, the Company has continued to conduct further evaluation including grade control drilling to produce a better geological understanding of the orebody. Utilising this information an optimal new mine plan has been produced.

The previously published DFS mine plan ceases to provide sufficient operational flexibility during the production phase and has an increased execution risk when considering potential operational outages. This is primarily due to the DFS mine plan being based on a single starter pit, minimising operational face lengths and also not allowing enough gold bearing ore to be built up on the stockpile to feed the plant in the event of an outage.

The new mine plan compensates for the delay and improves the Project’s economics. It reduces costs over the life of mine (“LOM”) and generates stronger cash flows, particularly during the ramp-up period and first six months of production, producing significantly increased free cash flow after debt servicing.

The principal benefits of the new mine plan relative to the existing DFS plan are listed below:

  • Stronger cash generation, particularly in the early stages of the Project, which will provide more cash for exploration and working capital
  • Greater operational flexibility through the creation of two starter pits, providing increased face length and stockpile management and giving greater confidence that production targets will be met
  • Increased Run of Mine (“ROM”) ore stockpiles ensure against any unforeseen production disruption
  • Reduction in mining cash costs based on more efficient mining by utilizing the layout of the mining infrastructure, such as the waste dumps

The new mine plan involves a revised mining sequence, now running from East to West, which utilises two shallower starter pits at Kinjor and Larjor. This provides increased operational flexibility due to the increased workable face lengths and allows access to areas of high grade ore earlier in the LOM. A drainage berm surrounding the open pit, which is constructed from waste rock, has also been incorporated into the new mine plan. The construction of this berm not only shortens the haulage distance for waste rock, but also lowers the Project execution risk in the wet season by safely reducing water ingress into the pit, minimising the pumping required to keep the pit fully operational throughout the wet season. For further details, please see the link below:

New Mine Plan Fundamentals

The new mine plan also incorporates increased efficiencies in the mining fleet and schedule, including “hot seat change over” at the start and end of shifts and the use of temporary haulage ramps to the north of the pit to minimise waste haulage distances. This enables more waste rock to be removed and ore to be mined and processed earlier in the mining schedule. The new mine plan also has the incremental benefit of the current low fuel prices, which helps to reduce the overall mining cost.

The incorporation of two starter pits combined with the increased mining and trucking efficiencies has allowed the Company to develop a more refined stockpile strategy than that outlined in the DFS. The increased early tonnage in the new schedule allows the Company to create a larger stockpile of ore on the ROM Pad, thus enabling higher ore grade material to be blended and fed to the process plant earlier than in the original schedule. This also provides an additional safeguard to any potential problems in the pit by having more ore material available for processing. The stockpile blending strategy facilitates a consistent grade of ore to be fed to the process plant. Additional oxide material will be blended with sulphide ore during dry seasons, improving plant throughput by some 15%.

The change in the mining schedule results in the completion of mining operations four months earlier than planned in comparison to the DFS when maintaining all other material parameters. The revised production profile is more appropriately aligned to the current gold price environment and the basis of the new plan is that 10% more ore material is mined and 35% more gold is produced in 2015 in comparison to the delayed DFS mine plan (described below). These revisions more than adequately compensate for the delay in processing operations caused by the Ebola outbreak.

The key Project parameters comparing the existing DFS mine plan to the delayed DFS mine plan and the new mine plan can be summarised as follows:

A series of graphs comparing the new mine plan against the DFS mine plan are presented below:

New Mine Plan v DFS Mine Plan

The total cost associated with implementing the new mine plan is approximately US$ 15 million and relates to the increased pre-strip mining activities occurring over the delay period. The total cost can be summarised as follows:

Additional costs of new mine plan US$ million
Mining labour and ancillary costs 1.9
Heavy mining equipment hire 7.9
Support equipment hire 0.6
Fuel 2.1
Blasting consumables 1.7
Other consumables 0.8
15.0

As at 31 December 2014, the Company had cash resources of approximately US$ 33 million and US$ 20 million of undrawn debt finance facilities, having drawn down US$ 80 million of the debt finance facilities. Net proceeds of the Subscription and Offering will be used to finance the new mine plan with the remaining funds coming from the Company’s existing cash resources. The existing debt finance facilities and remaining existing cash resources will finance the completion of the construction of New Liberty and fund general working capital.

Grade Control Drilling

Reverse-Circulation (“RC”) grade control drilling has been completed for the Year 1 mining schedule. The assay results show excellent correlation with and confirm the original Resource model interpretation and the revised wireframe shows slightly higher grade and more volume in some areas of the deposit. The Year 1 pit in the new mine plan focuses on mining the high grade intersections in the near-surface area of Larjor and this detailed grade control drilling will help to enhance grade management and enable better spatial definition of the high grade zones.

Further details on the Year 1 Grade Control Programme are available below:

Grade Control

Reserve Statement

The Reserve for the new mine plan is consistent with that used in the DFS mine plan and has only been subject to scheduling changes in the way that it is mined. All other parameters remain unchanged.

The Reserve statement for the National Instrument 43-101 (“NI 43-101”) compliant DFS for the New Liberty Gold Project was based on the Resource statement that was announced on 1 October 2012. The Reserve statement was compiled by AMC Consultants (“AMC”) with contributions from DRA Mineral Projects (“DRA”) for metallurgical recovery and processing costs and initial capital numbers. The Reserve estimate was undertaken by AMC in accordance with the requirements of NI 43-101.

The total mineral reserve estimate of 923,716 oz of gold grading 3.4 g/t is comprised of 704,600 tonnes grading 4.4 g/t (for 99,470 oz) in the proven mineral reserve category and 7,789,500 tonnes grading 3.3 g/t (for 824,246 oz) in the probable mineral reserve category, as detailed in the table below. The proven mineral reserve and probable mineral reserves are contained within open pits of depths between 180 and 220 metres below surface. The ore body is still open at depth.

The Reserve estimate can be summarised as follows:

Mineral Reserve Classification Tonnes Gold (g/t) Contained Gold Koz
Proven Mineral Reserve 700,000 4.4 99
Probable Mineral Reserve 7,800,000 3.3 825
Total Proven Mineral Reserve and Probable Mineral Reserve 8,500,000 3.4 924

Notes:

1. The Mineral Reserve was estimated by construction of a block model within constraining wireframes and based on measured mineral resources and indicated mineral resources

2. The Mineral Reserve is reported at a cut-off grade of 0.8 g/t Au and ore grading between 0.8 and 1.0 g/t cut-off is stockpiled for processing towards the end of the mine life

3. A dilution skin of 0.5 m added and a minimum mining width of 2.5 m was applied

4. The Mineral Reserves were estimated based on the updated NI 43-101 Mineral Resource

5. The cut-off grade of 0.80 g/t was used for pit optimisations and were based on a gold price of US$ 1,300 / oz

6. A 93 % metallurgical gold recovery was used

7. Due to rounding, some columns or rows may not add up exactly to the computed totals

New Mine Plan – Accretive to All Stakeholders

The new mine plan de-risks the production phase of the Project, particularly in the earlier part of the production period, due to the following factors:

  • Increases expected LoM cash generation by US$ 51 million
  • Reduces expected All-In Sustaining Cash Cost1 by 7%
  • Accelerates expected cash flow with an expected additional 28,000 ounces of gold produced in first year of production

Operational Update – New Liberty Open Pit Pre-Stripping Initiated, First Blast Completed and Plant Build 75% Complete

Further to the commencement of pre-strip mining operations in October 2014, mining of first ore in the Larjor pit has commenced. Mining activities have focused on the upper levels of the Larjor pit, where mining levels are being established within the pit boundary. Gold bearing oxide, fresh ore and mineralised waste is currently being stockpiled in preparation for the commencement of processing. For these mining and pre-strip activities a Komatsu PC1250 excavator was matched to Caterpillar 740 Articulated Dump Trucks (“ADT”). The main fleet consisting of Komatsu 785 Dump Trucks have arrived on site and has been commissioned on time for taking over from the existing ADT fleet during the first quarter of 2015.

First Blast

The first two blast blocks were completed in the Larjor area of the New Liberty Open Pit on 24 January and 28 January 2015. Each blast block was made up of approximately 300 blast holes and each resulted in the blasting of 25,000 tonnes of waste rock, achieving excellent fragmentation. This fresh rock is now being used for construction purposes, which includes the construction of a protective flood bund around the Larjor pit area.

For further details of the first blast, please see gallery below:

Construction Update Jan15

Plant Construction

Construction activities at the Project are progressing well with the Engineering, Procurement and Construction Management (“EPCM”) contract 75% complete as of 16 January 2015. The Primary and Secondary Crushers and Ball Mill are now fully installed and awaiting power for directional testing.

A milestone was recently achieved when the reagent mixing area, plants and all pipe racks were handed over to the structural steel, mechanical, plate work and piping (“SMPP”) contractor for construction.

Other Highlights

The accommodation blocks at Camp David for visitors and junior and senior employees have been completed and are now occupied. The potable water plant has been commissioned and work has started on the sewage plant. The plant administration buildings are now also fully completed and the offices are occupied by both the EPCM contractor and owners teams. The plant stores and workshop have also recently been completed and are ready for occupation.

Orders for reagents have also been placed with suppliers and the first batch of reagents is currently shipping to site in preparation for the commencement of processing operations.

Details on the overall construction progress are included in the following illustration:

With respect to forward looking information contained in this news release and the documents hyperlinked herein, 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.

Actual results could differ materially from those anticipated in the forward looking information contained in this news release and the documents hyperlinked herein as a result of the risk factors, including: risks normally incidental to exploration and development of mineral properties; the inability of the Company to obtain required financing when needed and/or on acceptable terms or at all; risks that the cost of implementing the New Mine Plan and the operating cash costs of the New Liberty Gold Project exceed those estimated in the New Mine Plan; risks related to operating in West Africa; health risks associated with the mining workforce in West Africa; risks related to the Company’s title to its mineral properties; adverse changes in commodity prices; risks related to current global financial conditions; risks that the Company’s exploration for and development of mineral deposits may not be successful; risks normally incidental to exploration and development of mineral properties; the inability of the Company to obtain, maintain, renew and/or extend required licences, permits, authorizations and/or approvals from the appropriate regulatory authorities and other risks relating to the legal and regulatory framework in Liberia, including adverse changes in applicable laws; competitive conditions in the mineral exploration and mining industry; risks related to obtaining insurance or adequate levels of insurance for the Company’s operations; uncertainty of mineral resource and reserve estimates; the inability of the Company to delineate additional mineral resources; risks related to environmental regulations; uncertainties in the interpretation of results from drilling; uncertainties in the estimates and assumptions used, and risks in the methodologies employed, in the New Liberty Technical Report and that the completion of additional work at the New Liberty Gold Project could result in changes to the forecasts, estimates and expectations contained in the New Liberty Technical Report; risks related to the legal systems in Liberia; risks related to the tax residency of the Company; the possibility that future exploration, development or mining results will not be consistent with expectations; delays in construction; inflation; changes in exchange and interest rates; risks related to the activities of artisanal miners; actions of third parties that the Company is reliant upon; lack of availability at a reasonable cost or at all, of plants, equipment or labour; the inability to attract and retain key management and personnel; political risks; the inability to enforce judgments against the Company’s directors and officers; the inability of Aureus to obtain TSX approval of the Offering and Subscription; the inability of Aureus to complete the Offering and the Subscription; risks related to the Ebola crisis; and future unforeseen liabilities and other factors.

Disclosure herein of exploration information and of mineral resources and mineral reserves is derived from the New Liberty Technical Report. Information relating to “mineral resources” and “mineral reserves” is deemed to be forward looking information as it involves the implied assessment based on certain estimates and assumptions that the mineral resource and mineral reserves can be profitable in the future. 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. By their nature, mineral resource and reserve estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable. If such mineral resource estimates are inaccurate or are reduced in the future, this could have a material adverse impact on the Company. Accordingly, readers should not place undue reliance on forward looking information. Mineral resources that are not mineral reserves do not have demonstrated economic viability. 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.

The forward looking information included in this news release and the documents hyperlinked herein is expressly qualified by this cautionary statement and is made as of the date of this news release. The Company does not undertake any obligation to publicly update or revise any forward looking information except as required by applicable securities laws.
