|Thursday, 19 January 2012 00:00|
Energizer Resources Inc. (TSX: EGZ) (OTCBB: ENZR) (FWB: YE5) (“Energizer” or the “Company”) is pleased to announce preliminary results from exploration programs on its Green Giant, and Malagasy Minerals Limited (“Malagasy”) (ASX: MGY) Joint Venture (JV) properties in Madagascar. Drill core assays received to date from the Phase I exploration program, have yielded intersections assaying up to 7.46% carbon (C) over 61.4 metres in length. Multiple graphitic zones discovered during the course of the Phase II exploration indicate the Company has begun to outline a new graphite camp. Highlights of the Phase I and II exploration programs are as follows, with a summary of drill core assays provided at the conclusion of this release:
Phase I Exploration – Green Giant Property
Phase II Exploration – Green Giant Property
Phase I Exploration
Graphite Identified in Manga Vanadium Deposit Presents Dual Opportunity
The mineralization delineated in the Company’s NI43-101 compliant vanadium resource was found in two types of rocks, silicates and oxides. Petrographic descriptions undertaken on thin sections of selected rocks submitted for metallurgical analysis to Mintek of South Africa, identified 17.17% modal graphite from the silicate composite and 15.87% modal graphite from the oxide composite samples. As vanadium and graphite are considered to be strategic minerals, the Company will position itself to deliver a dual offering of strategic minerals from a single source for energy storage, as well as steel and other innovative products.
Three additional composite samples were submitted to Mintek at the conclusion of the 2010 exploration program. Mintek reported analyses of these samples to Energizer in December, 2010 and January, 2011. The QEMSCAN1 analysis of these head samples quantified a graphite composition of 4.09%, while the head chemical analysis quantified a graphitic carbon content of 3.87%.
5 Graphite Zones Identified to date on Green Giant Property
The identification of graphite as a potential credit to the Company’s NI 43-101 compliant vanadium resources led Company geologists to conduct a reconnaissance exploration program (Phase I program) on the Property in September, 2011, with the goal of delineating new graphitic trends, and comparing them to those associated with vanadium mineralization.
During the course of the Phase I program, surficial graphitic trends were identified on the Green Giant Property. These graphite trends were visually determined to be of both higher carbon content, and larger flake size than those associated with the NI 43-101 compliant vanadium resource mineralization. Based on these field observations, the Company initiated an exploration program which included 10 diamond drill holes (totalling 1157.5 metres), 16 trenches (totalling 1912 metres), and 132 grab samples collected over two newly identified prospective graphitic units, named the Fondrana and Fotsy zones, bringing the total number of Graphite Zones on the Property to 5.
Phase II Exploration
Based on the promising results of the Phase I program, the Company launched the Phase II exploration program in November, 2011. The objective of the program was to enhance exploration efforts on the Green Giant property through further drill testing of graphitic trends on the Green Giant Property and to apply geophysical techniques to delineate graphite mineralization. The signing of the JV agreement with Malagasy in November, 2011 for the exploration and development of industrial minerals, prompted additional reconnaissance exploration to ascertain the industrial mineral potential of the joint venture property.
Geophysical Tools Employed to Identify Multiple Graphite Mineralization Trends
Over the course of exploration activities on the Green Giant property, Energizer completed a DIGHEM EM/Magnetic Airborne survey (in 2007 by Fugro Airborne Surveys Limited), and an AeroTEM IV Time Domain Airborne Electromagnetic survey (in 2011 by Aeroquest Limited). Company geophysicists have utilized these geophysical surveys to identify multiple graphitic trends on the Green Giant property. With the acquisition of additional airborne geophysical data (Geotech VTEM survey) flown over the JV property provided by Malagasy, Company geologists have further delineated the known graphitic trends.
Potential Flake Graphite Camp
During the course of the Phase I and II exploration programs, multiple graphitic or graphitic-vanadium trends were identified with the aid of airborne geophysics, and subsequently verified with ground prospecting, and delineated with the use of an EM31-MK2 (EM31) instrument. In total, 12 new graphite trends have been identified over the JV property. This brings the total number of graphite trends identified to date over the Green Giant and JV properties to 17, with a cumulative strike length in excess of 320 km. These observations have validated the Company’s belief that southern Madagascar has the potential to host a potential flake graphite camp.
The graphite trends identified to date are named as follows:
Multiple Graphitic Horizons Identified Within Each Zone With EM31
Field observations indicated that each graphitic zone identified, was comprised of multiple ‘stacked’ graphitic horizons. This observation was validated by surveying a number of the zones in detail with an EM31 ground conductivity instrument. In total, 160.5 line kilometres of EM31 surveying was completed over 5 target areas, the Fondrana, Fotsy, Molo, Seta, and Besavoa targets.
The EM31 geophysical tool was invaluable in delineating the extents of the graphitic zones, as well as their continuity. The EM31 has the capability to also identify multiple graphitic horizons within each zone. As an example, the Fotsy zone has a delineated strike length of 6 kilometres, but the EM31 identified at least 4 separate graphite horizons within the zone, for an aggregate strike length of 24 kilometres. The table below summarizes the graphite strike length analysis as determined by EM31 testing over 5 zones:
Structurally ‘Thickened’ Graphite Zone Identified
Our geoscientists have identified a graphitic zone consisting of multi-folded graphitic strata with a surficially exposed strike length of over 2 kilometres. This zone, called Molo, is characterized by resistant ridges of graphitic schist, and abundant graphitic schist float, with fracture-lined vanadium mineralization yielding field XRF values as high as 0.7% V2O5. Geologic mapping has revealed the individual graphitic ridges to be between 20 and 150 metres in width within this zone. EM31 surveys indicate the graphite mineralization is pervasive in the area, and that the mineralization is not always exposed. Wide-spaced drilling of 6 diamond drill holes conducted over a strike length of 1.2 kilometres, intersected graphitic mineralization to a vertical depth of 75 metres with down-hole thicknesses between 60 and 150 metres in width. Graphite mineralization intersected in drill core was open along strike, and at depth.
Craig Scherba, Vice President of Exploration commented, “The graphitic zones we have identified in the Molo zone are exposed at surface, and appear to have a graphitic carbon content as high, if not higher than anything else we have seen on the properties. The integration of airborne geophysics, coupled with EM31 ground surveying, diamond drill intercepts and our geologic understanding of the area, indicate that an aggressive exploration program is warranted for the area”.
Vanadium Trend Extended On To JV Property by 30 km
The 21 km vanadium trend found on the Green Giant property has now been increased by an additional 30 km on the Malagasy JV property. This trend was delineated through the analysis of soil samples with a hand-held XRF analyzer at 25 metre station intervals, and 200 metre line spacing. XRF analysis was an invaluable tool in delineating the original Green Giant vanadium trend, and enables the Company to make ‘real-time’ exploration decisions based on field results.
In the course of XRF soil analysis on the JV property, a 1.6 kilometre outcrop of graphitic schist, named the Seta zone, was identified adjacent to the vanadium trend. Geologic mapping in the area indicates that this zone is sub-horizontal, and roughly 20 metres in thickness.
Exploration activities during the course of the Phase I program included 10 diamond drill holes (totalling 1157.5 metres) 16 trenches (totalling 1912 metres), and 132 grab samples. An additional 19 diamond drill holes (totalling 2701 metres) and 518 grab samples were completed during the course of the Phase II exploration program. All samples collected during the exploration programs were submitted for graphitic carbon analysis.
To date, only one quarter of drill hole assays, and one fifth of grab sample assays have been received. No trench sample analyses have been received. Of the samples received, diamond drill core assays as high as 21.0% carbon, and grab samples as high as 21.3% carbon have been received, with the most significant intersection being 7.46% carbon over 61.4 metres down-hole length.

It would be appropriate at this time to comment on time lines related to receipt of assays, and the need for metallurgical analysis to fully outline the type and quality of the graphite on the properties. The Company believes that after receiving assays it is both prudent and necessary to wait for the metallurgical analysis to fully inform the market of the potential of the graphite identified to-date, but it should be noted that the Company is comfortable in identifying the graphite as flake based on visual observation and cursory testing. The Company will endeavour to expedite the metallurgical process throughout its exploration programs.
Graphite and diamonds are the only two naturally formed polymers of carbon - graphite is a two-dimensional crystal structure, whereas diamonds are a three dimensional structure.
Graphite is an excellent conductor of heat and electricity, and has the highest natural strength and stiffness of any material. It maintains its strength and stability to temperatures in excess of 3,600°C and is very resistant to chemical attack. At the same time it is one of the lightest of all reinforcing agents and has high natural lubricity.
The U.S., who is a 100% importer of graphite, has joined China and the European Union in classifying graphite as a critical strategic material.
