Focus Graphite Releases Infill and Deposit Margin Drilling Results at Lac Knife Deposit : 42.8 m grading 20.43% Cgr in Hole LK-12-128
April 9, 2013 (Source: Marketwire) Ottawa, ON — Focus Graphite Inc. (TSX VENTURE:FMS)(OTCQX:FCSMF)(FRANKFURT:FKC) (“Focus” or the “Company”) is pleased to report the results of the summer 2012 infill and deposit margin drilling program on the Company’s 100%-owned Lac Knife graphite Property (the “Property”), located in the Grenville Geological Province of northeastern Québec. Fifty-six (56) large diameter (PQ-sized) core holes (total: 5,638 m) were drilled with the aim to upgrade the current Inferred mineral resources in the southeastern part of the Lac Knife deposit to the Indicated category; to map the limits of the deposit; and to provide sufficient mineralised feed material for phase II lock cycle metallurgical testing and for the pilot plant testing program currently scheduled to commence this month.
- Hole LK-12-128 drilled on Line 500 S targeted the western zone of the deposit and returned one of the best graphitic carbon (Cgr) intersections of the program (Table 1):
- Hole LK-12-128: 42.8 m grading 20.43% Cgr (from 60.7 to 103.5 m), including 11.8 m grading 36.08% Cgr (from 79.7 to 91.5 m)
Most of the drill holes intercepted significant graphite intersections* along the strike length of West, Central and East zones of the deposit as evidenced by the following Holes:
- Hole LK-12-135 drilled on section 675 S: 60.5 m grading 17.88% Cgr (from 61.0 to 121.5 m), including 13 m grading 32.33% Cgr (from 70 to 83 m) and 11.8 m grading 26.39% Cgr (from 106.7 to 118.5 m)
- Hole LK-12-147 drilled on section 375 S: 42.8 m grading 17.59% Cgr (from 12.4 to 55.2 m), including 5.4 m grading 39.56% Cgr (from 15.4 to 20.8 m)
*Significant intercepts are defined as Cgr > 5% over a minimum of 6 m; maximum internal dilution of 6 m; maximum external dilution of 0 m.
Focus Graphite President and CEO Gary Economo states: “We are extremely pleased with the results of our infill resource drilling program at Lac Knife which continue to deliver high graphite grades over significant thicknesses in both the West and Central zones of the deposit. The 2012 drilling was primary designed to improve our current understanding of the limits, geometry, and continuity in thickness and grade of the graphite mineralisation, key elements required to upgrade our current mineral resource estimate and map additional resources. Our summer 2013 exploration program at Lac Knife will include additional resource drilling to consolidate the size and limits of the deposit”.
The mineralization at Lac Knife is hosted in biotite-quartz-feldspar paragneiss and schist of the Nault Formation, in association with iron formations of the Wabush Formation. These are equivalent to the lower Proterozoic Labrador Trough rocks affected by the late Proterozoic Grenvillian orogeny. Metamorphism associated with the Grenvillian orogeny has resulted in the formation of economic grade concentrations of graphite dominated by value-enhanced large flakes.

The Lac Knife property comprises 57 map-designated claims covering 2,986.31 ha located in Esmanville Township (NTS map sheet 23B/11), 27 km south-southwest of the iron-mining town of Fermont, in the Côte-Nord administrative district of Québec. Focus acquired a 100% interest in the property in October 2010.

2012 Infill and Deposit Margin Drill Program, Methodology and QA/QC
The summer 2012 infill and deposit margin drilling program at Lac Knife comprised 56 large diameter (PQ-sized, 4-inch) core holes for a total of 5,628 m. The drilling program was designed to map the limits of the Lac Knife graphite deposit and provide sufficient additional data and control on mineralisation to be useful for in a new resource estimate. The drilling was also designed to provide enough mineralised material for phase II metallurgical testing (see Focus’ press release dated March 4th) and for subsequent pilot plant trials.
The 2012 drilling campaign was managed by IOS Services Geoscientifiques (“IOS”) of Chicoutimi, Québec. The infill and deposit margin drilling program started on July 1st and ended on September 17th 2012. The drilling was performed by G4 Drilling of Val-d’Or, Québec under the supervision of IOS.
The 56 holes were spread over the western, central and eastern zones of the deposit (see drill holes location map available on the Company’s website at www.focusgraphite.com).
Two slabs of about 1/4 of the 4 inch diameter PQ core were sawed parallel on each side of the central axis of the core. One of the slabs was earmarked for geochemical analysis while the other slab was kept as a witness sample. Center parts of the core were used as graphite-bearing material for the phase II metallurgical testing and for the subsequent pilot plant testing program.
A total of 2,076 sub-sample slabs of the PQ drill core were collected from all 56 holes and shipped to IOS for sample preparation (crushing and grinding). Once prepared, the samples were sent to the Consortium de Recherche Appliquée en Traitement et Transformation des Substances Minérales (“COREM”), an ISO/IEC 17025:2005 certified facility in Québec-City, for graphitic carbon (Cgr) analysis using LECO high frequency combustion method with infrared measurement (internal analytical code LSA-M-B10 for graphitic carbon; ISO 9686:2004). For the measurement of graphitic carbon, the sample is pre-treated with nitric acid, placed in a LECO capsule and introduced in the furnace (1,380ºC) in an oxygen atmosphere. Carbon is oxidized to CO2. After the removal of moisture, gas (CO2) is measured by an infrared detector and a computerized system calculates the concentration of graphitic carbon (Cgr). Total sulphur was also analyzed by LECO (code LSA-M-B41) (Table 1). For sulphur determinations, the sample is placed in a LECO capsule and introduced in the furnace (1,380ºC) until sulphur is oxidized to SO2. After the removal of moisture, gas (SO2) is measured by an infrared detector and a computerized system calculates the concentration of total sulphur (%).
Under the QA/QC program, about 10% of the samples were analyzed by COREM for total (code LSA-M-B45), organic (code LSA-M-B58), inorganic (code LSA-M-B11) and graphitic (code LSA-M-B10) carbon as well as for total sulphur (a total of 191 core samples). Duplicates of the same 191 samples were also sent to ACTLABS Laboratories of Ancaster, Ontario (ISO/IEC 17025:2005 with CAN-P-1579) for graphitic carbon (code 5D – C Graphitic) and total sulphur (code 4F – S Combustion infrared detection) determinations and for 35 multi-element analysis using ICP methods (code 1E2 – Aqua Regia). IOS introduced 181 standards, 173 duplicates and 159 blank samples into the batch of core sample as part of the QA/QC program.
Summer 2013 Drilling Program
Focus is currently working on the design of a two-phase follow-up drilling program on the Lac Knife property for the summer of 2013. Phase I of this program will include additional infill drilling within the limits of the deposit defined by the NI 43-101 compliant mineral resource estimate (see Lac Knife PEA Technical Report available on Focus’ website or at www.sedar.com). Phase II will consist of an exploration drilling program in order to test geophysical anomalies identified during last fall’s ground magnetic and horizontal loop electromagnetic (HLEM) survey done by G.L. Géoservice Inc. and interpreted by Geophysique Camille St-Hilaire Inc., both located in Rouyn-Noranda.
