MONTREAL, Sept. 4, 2013 /CNW Telbec/ - Colt Resources Inc. ("Colt" or the "Company") (TSXV: GTP) (FRA: P01) (OTCQX: COLTF) is pleased to announce the results of a positive Preliminary Economic Assessment ("PEA") prepared by SRK Consulting (UK) Ltd ("SRK") for the 100% Colt-owned Tabuaço Tungsten Project, located in Portugal.  The final PEA report will be filed on SEDAR within 45 days.  The PEA covers the São Pedro das Águias (Tabuaço) tungsten deposit and the nearby Aveleira tungsten deposit, both located within the Company's Tabuaço Experimental Mining License (45 km2).

Nikolas Perrault, CEO and President of Colt stated; "We are very pleased with the results of this PEA prepared by SRK. It demonstrates the potential to develop this project with positive economics.   While initiating the Feasibility Study, Colt's next phase of work will include upgrading the inferred resources to indicated resources and identifying additional resources in close proximity to the known deposits."

Preliminary Economic Assessment Summary

A PEA was prepared by SRK for Colt's 100% owned Tabuaço Tungsten Project in Portugal.  The PEA relied on NI43-101 compliant Indicated and Inferred Mineral Resources as announced by Colt on October 3rd, 2012.

The main conclusions from the PEA are shown on Table 1. All values are in USD and the study assumes a USD 1.30/EUR exchange rate.  A flat tungsten price of USD 400/MTU W03 was used in the economic assessment.  Capital and operating costs were derived from a combination of first principles and SRK's experience based on similar projects.

The conclusions and recommendations of the PEA are that the Tabuaço Tungsten Project may be economically viable and that further studies and field work for this project are justified.

SRK notes that the economic assessment is preliminary in nature and the production schedules are inclusive of inferred classified mineral resources that are considered too geologically speculative to have economic considerations applied to them that would enable them to be classified as Mineral Reserves.  There is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Metal Price Sensitivity Analysis
The impact of a range of tungsten prices on the NPV5% for the project has been studied in the PEA and the results are reported in Table 2.

Discount Rate Sensitivity Analysis
The impact of a range of discount rates on the NPV for the project has been studied in the PEA and the results are reported in Table 3.

Discount rate USD/MTU 0.0% 2.5% 5.0% 7.5% 10.0% 12.5% 15.0% 17.5% 20.0%
NPV USDm 109.2 85.8 67.4 52.7 41.0 31.7 24.1 17.9 12.9

Several processing options were evaluated for the Project and the economic assessment presented here is based on Colt's preferred base case, which uses ore sorting and an acid tungsten recovery process. It is noted that the planned trial mining will provide a bulk sample for further testwork to verify the flowsheet.

Project Timeline and Optimization Efforts

The completion of this positive PEA is an important milestone in the continued development of the Tabuaço Tungsten Project.

Colt's projected timeline to advance the project includes the following milestones:

Q4 2014

Completion of Resource Update / Feasibility Study


Full Mine Permitting





Colt intends to address several areas during the Feasibility Study so as to improve results included in the PEA.  These will include:

Mineral Resources - Colt will focus on upgrading of Inferred Resources to Indicated Resources and the identification of additional resources in close proximity to the known deposits.  Colt is confident that the potential to increase resources through regional exploration is good.  Exploration work will be directed toward identifying additional resources that will benefit the future mining operation.

Trial Mining - Colt will develop an adit to the orebody to determine the geotechnical and mining conditions and to take a bulk sample for metallurgical testwork.

Processing - Colt will complete ongoing testwork so as to finalize and optimize process flowsheets leading to final plant design.  The study analysed several options that will be further evaluated and finalized.

Geotechnics - Colt will perform additional geotechnical investigations designed to determine the ground support requirements.

Environmental - Work will continue to address the need to minimize the impact of the future mining project.

Mining - Capital and operating costs will be confirmed and addressed in detail to identify areas where improvements can be made so as to benefit the future economics of the project. The mine design will be updated based on the updated resources.
