Montero Mining and Exploration Ltd.: Moyale Displays Favorable Graphite Characteristics for Development
October 7, 2014 (Source: Marketwired) — Montero Mining and Exploration Ltd. (TSX VENTURE:MON) (“Montero”) is pleased to announce the results of a review of existing information completed on the Moyale Graphite Project in Ethiopia by Don Hains, P. Geo., of Hains Engineering in Toronto. The Moyale deposit is described as having favorable characteristics for development as compared to other global flake graphite deposits.
Don Hains, P.Geo, an expert on graphite geology, has compiled an initial review of historical data and provided a high level summary report to Montero.
A summary of the report prepared by Don Hains was based on previous work undertaken by the Ethiopian Institute of Geological Survey (EIGS) in cooperation with the Norwegian Geological Survey (NGU). The report details the following on the Moyale deposit:
- An average grade of 8% graphite carbon.
- Graphite distribution of 40% Jumbo flake and 28% Large flake.
- Initial trial bench-scale flotation indicated recoveries of up to 94-95% of rougher concentrates.
- The deposit is open at depth and along strike
|Dr. Tony Harwood, President and Chief Executive Officer of Montero commented, “I am pleased to announce that the Moyale Graphite Project has been identified as a quality deposit compared with other global flake graphite deposit by Don Hains, a recognized graphite industry expert. The favorable grade, deposit geometry, metallurgy, and flake size analysis which show 40% Jumbo and 28% Large flake graphite mineralization bode well for its exploration potential.”|
A historic resource estimate of 460,000 t of contained graphite (Cg) has been developed by the Ethiopian Institute of Geological Surveys (EIGS) in 1999. The historic estimate was based on a cross sectional area methodology for trench profiles assuming a vertical depth of 40m for mineralization for Area II and 20 m for Areas II and III. Data for the estimate was developed from 253 composite samples (2-3m) conducted in 42 trenches during the mid-1990’s. Overburden thickness was estimated at approximately 1m thickness and overburden volume estimated approximately equal to the block length. An average specific gravity of 2.2 g/ cm3 was used for mineralized zone and 2.0 g/cm3 used for overburden. The resource estimate excluded very thin graphite bearing zones. The table below summarizes the historic resource estimate.

The historic estimate is not an NI 43-101 compliant resource and is provided only as an indication of the exploration potential of the property. Montero is not treating the historical estimate as a resource and the historic estimate should not be relied upon. No Qualified Person (QP) as defined under NI 43-101 has undertaken sufficient work to verify the historical estimate as a current mineral resource. Retrenching and resampling will be required to verify the historical estimate.

The graphite bearing horizons have been mapped and systematically sampled in shallow trenches. There is significant initial preliminary evidence to demonstrate upside exploration potential at Moyale. An exploration target on the order of 1.5 Mt of contained graphite (Cg) from the three defined areas combined has been developed, assuming that the graphite mineralization has grade and thickness continuity down dip to 100 m vertical depth. Given the current annual demand for natural flake concentrates this would be more adequate as the basis for conducting feasibility studies.
A phased evaluation program of data verification, ground truthing, trenching/pitting and resampling and core drilling has been proposed to assess the mineral potential to a vertical depth of 100m. Metallurgical testwork will form an integral part of the program which is planned to lead to preparation of an NI 43-101 compliant resource and Preliminary Economic Analysis. The budget for the full program is estimated at approximately $1.5 million including contingency allowance.
Key characteristics of the Moyale Graphite deposit are noted in the table below:
|Area 1||8-10||Med-Coarse||2-Main||18-35||500 -700
(Open to W)
|Uniformly thick continuous along strike for 100’s of metres|
|Area 3||5-11||Fine||2-Main||6 – 30||1350
(Open to E)
|Uniformly thin continuous along strike – grades generally erratic and increases in grade to south-east|
|Area 2||7-14||Coarse||Multiple||7 – 60||100-550||Generally discontinuous along strike|
