The ball mill, together with the mill motors and primary crusher, arrived at the New Liberty site on schedule on June 10, 2014.  Following the announcement on March 18, 2014 on the completion of the ball mill foundations, this is another major achievement and is a key milestone in the overall New Liberty project construction schedule. 

The ball mill, which is 17 ½ foot x 23 ½ foot, will take between four to six months to erect, with commissioning starting in Q4 2014 and scheduled to be completed in Q1 2015.  The mass of the complete ball mill installation, in a ready to run state, is approximately 250 tonnes and its power consumption will be 3,500kW.  The nameplate capacity of the ball mill is 145.5 metric tons per hour. 

The ball mill was transported by sea from the port of Durban in South Africa to the port of Monrovia in Liberia and then by road from the port of Monrovia to the New Liberty site.  The shipment also included other large items such as the Joest vibratory screens as well as plant steelwork.  Please refer to the following link for pictures of the transportation process:

Forward Looking Statements

Certain information in this news release relating to Aureus is forward-looking and related to anticipated events and strategies. When used in this context, words such as "will", "anticipate", "believe", "plan", "intend", "target" and "expect" or similar words suggest future outcomes.  Forward-looking information contained in this press release includes, but may not be limited to, mineral reserve and mineral resource estimates, the expected mine life and production of the New Liberty Gold Project  and the anticipated exploration and development activities of Aureus. By their nature, such statements are subject to significant risks and uncertainties that may cause actual results or events to differ materially from current expectations, including: risks normally incidental to exploration and development of mineral properties; uncertainties in the interpretation of results from drilling and test work; the possibility that future exploration, development or mining results will not be consistent with expectations; regulatory and government decisions; the possibility that future drawdowns under the loan facilities may not be available; construction of the New Liberty Gold Project being delayed and/ or over budget; economic conditions; availability and cost of financing; estimates of capital and operating costs and start-up costs; plans regarding construction activities; and future unforeseen liabilities and other factors including, but not limited to, those listed under "Risk Factors" in the Company's Annual Information Form dated March 25, 2014, a copy of which is available on SEDAR at www.sedar.com, and in the Aureus Mining Admission Document, a copy of which is available at www.aureus–mining.com.  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.

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.
