Technical Reports

The La Verde Project consists of a concession totalling approximately 7,904 hectares. Within the concession, mineralization is hosted within a mid-Tertiary granodiorite/quartz monzonite intrusive complex roughly 5.5 kilometres long and 1 kilometre wide; which is up to 750 metres above mean sea level (msl), known as the Sierra del Marqués intrusive complex. Historic exploration work included geological, geochemical and geophysical surveys as well as 80,000 metres of drilling.

The exposed porphyry copper system is amenable to open pit mining within the two known zones of porphyry style copper - gold - silver mineralization and with significant upside exploration potential.

An updated NI-43-101 compliant report entitled “Technical Report on the La Verde Property, Michoacán, Mexico”, dated September 19, 2012 (the “Technical Report”) was prepared for the Company by Margaret Harder, M.Sc, P.Geo. and Michael F. O’Brien, M.Sc., Pr.Sci.Nat., FGSSA, FAusIMM, FSAIMM of  Tetratech Wardrop, who are independent qualified persons as defined by NI 43-101.

The report presented the estimated Measured, Indicated and Inferred resources at La Verde as follows:

On January 18, 2013 the Company announced delivery of a NI 43-101 Technical Report; including a Preliminary Economic Assessment Study (“PEA”) completed by AMC Mining Consultants (Canada) Ltd. (effective date September 2012).  This Technical Report was based in part on the Tetratech Technical Report. Both technical reports are available under Catalyst’s profile at

Summary highlights of the PEA and 20 year Life of Mine (LOM) plan include:

Base case metal prices utilized for preparation of the  Mine Plan, and in the above table, were Cu-$2.70; Au $1200/ounce (“oz”); Ag - $25/oz. Financial estimates are earnings before income tax, depreciation and amortization allowances (“EBITDA”) and all dollars are US$.

2. Case B. Cu $3.64/lb; Au $1,455/oz; Ag $28.06/oz SEC Guidelines

3. Case C. Cu $3.00/lb; Au $1,200/oz; Ag $25/oz

4. Case D. Cu $2.40/lb; Au $1,200/oz; Ag $25/oz


The PEA is preliminary in nature and includes the scheduling of Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Reserves. There is no certainty that the results of the PEA will be realized. Investors are cautioned that the La Verde Project is at an early stage of development and no feasibility study has yet been undertaken. Further studies are required and include, but not limited to, drilling, metallurgical testing, geotechnical investigations and the ability of the Company to acquire surface rights, adequate waste and tailings storage areas, environmental permitting and the “Social licence” from the affected local communities to explore, develop and operate the Project.
