POSITIVE PRELIMINARY ECONOMIC ASSESSMENT FOR COLT'S 100% OWNED TABUACO TUNGSTEN PROJECT, NORTHERN PORTUGAL
Colt Resources Inc. has provided the results of a positive preliminary economic
assessment (PEA) prepared by SRK Consulting (UK) Ltd. for the
100-per-cent Colt-owned Tabuaco tungsten project, located in Portugal. The
final PEA report will be filed on SEDAR within 45 days. The PEA covers
the Sao Pedro das Aguias (Tabuaco) tungsten deposit and the nearby
Aveleira tungsten deposit, both located within the company's Tabuaco
experimental mining licence (45 square kilometres).
Nikolas Perrault, chief executive officer 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-per-cent-owned Tabuaco tungsten project
in Portugal. The PEA relied on NI 43-101-compliant indicated and
inferred mineral resources as announced by Colt on Oct. 3, 2012.
The main conclusions from the PEA are shown on the attached table. All values are
in U.S. dollars and the study assumes a $1.30-(U.S.)-to-euro exchange rate. A flat
tungsten price of $400 (U.S.) per thousand thermal units 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 Tabuaco
tungsten project may be economically viable and that further studies
and fieldwork 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.

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 Tabuaco tungsten project.
Colt's projected timeline to advance the project includes the following
milestones:
Fourth quarter 2014: Completion of resource update/feasibility study
2015: Full mine permitting
2015/2016: Construction
2017: Production
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 continuing testwork so as to finalize and
optimize process flowsheets leading to final plant design. The study
analyzed 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.
