Mandalay Resources Corporation Provides Update on Challacollo Infill Drilling and Feasibility Study Progress

TORONTO, Sept. 10, 2014 /CNW/ - Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND, MND.WT) is pleased to provide an update on the progress of its infill drilling and feasibility study at its Challacollo, Chile, silver-gold project (click here for Figure 1 Property Map).

Key activities to date include:

  • The General Manager and Construction Manager have been hired and are managing the feasibility and permitting work.
  • The major components of the feasibility study (e.g. drilling, assaying, metallurgical studies, hydrogeological studies, plant and tailings design, environmental impact evaluation, overall feasibility study preparation and the permitting application) have been tendered and contracts established with selected contractors.
  • Baseline studies of environmental, community and social aspects of the project are in progress as part of the permitting plan.
  • Infill drilling of the existing Inferred Mineral Resource is complete.  Through September 3, Mandalay had completed 6,469 meters of infill HQ diamond core in 36 holes.  Assays have been received for 23 of these holes as reported in Table 1 below.
  • Drilling has shifted to testing extensions of the main Lolon vein and other vein targets in the district.
  • Metallurgical testing (assaying, crushing, comminution, agitation leaching, filtration) of bulk underground and diamond drill core samples is in progress for process selection and plant design.
  • Groundwater exploration and well development planning is in progress along with the evaluation of other infrastructure requirements.

Brad Mills, CEO of Mandalay, commented, "The feasibility study launched in March of this year is on track for its intended conclusion in the first quarter of 2015.  We have identified and hired an excellent management team for the project, who are conducting the geological, metallurgical, hydrological, infrastructure, environmental and cultural studies at the planned pace and cost."

Mr. Mills continued, "Drilling results to date have demonstrated consistent continuity of mineralization and confirmed similar grades to those derived from previous drilling conducted by Silver Standard, from whom Mandalay purchased the project in February of this year.  These drill results are also consistent with the Independent Technical Report and Mineral Resource estimated by RPA, published in January of this year. These new results give us confidence that the program will be successful in its objective of upgrading substantially all of the previously Inferred Mineral Resource to Indicated, ready to convert to Mineral Reserves once they are incorporated into a mine plan as part of a successful conclusion of the feasibility study."

The Drill Program

The current drill program commenced in May, 2014, with the objective to infill some 3.9 million tonnes of Inferred Mineral Resources at 193 grammes per tonne ("g/t") silver and 0.32 g/t gold as estimated by Roscoe Postle Associates ("RPA") in their technical report dated January 30, 2014 and entitled "Technical Report on the Challacollo Silver-Gold Project, Region 1, Chile" (the "RPA Report") and convert them to Indicated and Measured categories to support the mine design portion of the feasibility study.

Infill core drilling of the resource portion of the Lolon vein is now completed. In addition we have identified extensions to the main Lolon vein and other nearby veins that could add to the mineral resource inventory and these targets are now being followed up with additional drill testing. All drilling activities are expected to be completed by October.

A complete description of the property, geology and resources at the time of acquisition in February, 2014, is contained in the RPA Report, available on www.sedar.com.

Mandalay follows a strict Quality Assurance and Quality Control ("QA/QC") program in accordance with industry standards that includes incorporation of blanks and standards in every assay batch as well as duplicate assays of selected samples.  Core is logged by Mandalay geologists before mineralized intervals are sawn in half. Mandalay geologists then bag half the core on-site for assay and store the remaining core for reference.  Samples are shipped to the ALS laboratory in Antofagasta, Chile, where Mandalay blanks are inserted before the samples are crushed and pulverized.  Mandalay certified standards, previously prepared from Challacollo material, are then inserted in each batch before the pulps are shipped to ALS in Lima, Peru, for analysis.

All samples are analyzed for 41 elements using ICP-AES with agua regia leach, as well as assayed using 30 g fire assay with gravimetric finish for Au and Ag in addition to cyanide leach for Ag, Au, and Cu.
