In 2010, a micro‐pilot plant study was completed at Drinkard Metalox Incorporated (DMI) to confirm engineering criteria for the production of high‐grade magnesia. This program used tailings material generated from a pilot plant scale talc flotation study. In 2011, deposit appraisal activities at TTM included the following activities: a) Jacobs Minerals Canada Inc. was retained to design and engineer a preliminary plant layout that would treat the primary material and produce high‐grade talc and magnesia. b) Mineral industry consultants Micon International Ltd, were originally tasked to deliver a Pre‐Feasibility Study (PFS) in 2011, but were subsequently directed by Globex to convert the PFS study into a Preliminary Economic Assessment (PEA). c) Contractor Blue Heron Environmental continued with base line environmental studies while Golder Associates Ltd. was retained to study waste stream storage requirements and to issue a conceptual pit slope design. d) Globex increased the size of the project by staking an additional 448 hectares to the west and south of the original property perimeter. Globex also presented an application to the provincial government to bring part of the property claims group in Deloro Township to lease. In 2012, the newly acquired western claims in the Deloro and Adams townships underwent preliminary exploration work consisting of line cutting, 29.7 km of combined ground magnetometer and VLF‐EM geophysical surveys and geological mapping. Work on the talc‐magnesite “A Zone” consisted of investigating an alternative talc processing method for the magnesite‐rich ore. Globex purchased 12 “surface‐rights‐only” (SRO) mining patents totaling approximately 167 ha (412.5 acres) from the City of Timmins. These patents are contiguous with a surface rights package purchased by Globex in 2000 and increase the area of SRO mining patents to about 485 ha. The purchase of the lands was done in order to facilitate construction and mine site infrastructure and any possible mill site that might be considered for TTM. Micon International Ltd. completed a Preliminary Economic Assessment of the Timmins Talcmagnesite deposit. This PEA, as detailed in a press release dated March 2, 2012, indicated a positive after‐tax NPV of $258 M at a discount rate of 8%, an after‐tax internal rate of return (IRR) of approximately 20% and a payback period of 5.8 years on the discount cash flow. This technical report is posted on SEDAR (www.sedar.com) and on Globex’s website (www.globexmining.com). The results of the PEA support the conclusion that further work is justified on the project, with an ultimate objective of completing a Feasibility Study. To this end, an infill‐surface program of 6,900m of diamond drilling was initiated in December with a view to improving and updating the 2010 resource estimate. The aforementioned drill program was completed in March 2013. This program was ultimately comprised of a total of 7,543 m of drilling in 53 holes consisting of 51 new holes and the extension of 2 existing Globex holes. Within this drill program, 7 of the holes totaling 1,178 m were utilized as part of a geotechnical investigation carried out by Golder Associates. These holes were logged by Globex personnel, but were not sampled. In 2013, a talc variability study was initiated in which a total of 35 samples of quartered core, representing 1,680 m of drilling in mineralized material, were collected to cover the extent of the A Zone. Individual in‐hole sample lengths for ranged from 26 m to 70 m (average length of 48 m) based on an initial nominal collection target of 60 m of representative talc‐magnesite for a particular target depth. The talc variability study looked to establish the potential variations throughout the deposit as well as assess the chemical and physical qualities of the high‐grade talc material. It was also meant to determine the final projected steady‐state talc concentrate grade and recovery factors from ore composites using locked cycle testing. This information will be used to inform further engineering and economic modelling. CTMP in Thetford Mines was selected to undertake the variability study, having the necessary research facilities and having demonstrated experience to make the required talc quality determinations. SGS‐Lakefield and Activation Laboratories provided QEMSCAN mineralogical and chemical analyses. The test work program to produce talc flotation concentrate samples for quality measurements was completed in mid‐2013 including talc product micronization and preliminary brightness measurements. In 2014, limited renewed funding for the TTM project was used to advance test work on talc quality and production, including an expanded CTMP testing program, locked cycle tests and Bond Work Index determination. Additionally, an enhanced range of physical quality assessments was conducted on compounded talc‐polypropylene formulations produced in a CTMP plastics research facility. Results for these tests are pending at the end of 2014. Based on budget constraints, Globex has deferred consideration of additional detailed engineering or pre‐feasibility studies until 2015. Globex continues to seek senior level financing to advance development of the TTM project. |
