European Electric Metals Samples High-Grade Cobalt and Nickel in Underground Sampling at Skroska
TSX VENTURE: EVX
- Elevated cobalt associated with the lower 2-meter samples averaging 0.14% Co and 1.19% Ni.
- Assays from 174 underground channel samples averaged 0.11% Co and 1.10% Ni.
- Elevated cobalt of up to 0.48% Co and 1.68% Ni identified in the sampling program.
VANCOUVER, British Columbia, Jan. 28, 2019 (GLOBE NEWSWIRE) -- European Electric Metals Inc. (TSXV-EVX) (“EVX” or “the Company”) is pleased to announce that it has received assay results from the Company’s Phase 1 underground sampling program in the Skroska Co-Ni laterite mine (see news EVX release dated November 12, 2018). The sampling program was undertaken to follow up on an earlier reconnaissance sampling which returned high cobalt and nickel assays (see EVX news release dated October 11, 2018 for details). The samples were collected from vertical channels in 66 locations in 4 blocks (see sampling locations on EVX website: Click Here. The samples were taken from vertical channels at one-meter intervals on mine walls up to 3 meters height (or headroom). The full thickness of the zone is not known and was not sampled due to limited underground exposures.
The samples were sent to ALS Laboratory in Bohr, Serbia for sample preparation with the analysis performed at ALS laboratory in Ireland. The analytical package used was ME-XRF-12n, an analytical suite suitable for nickel laterite samples which consists of16 elements including Ni, Co, Fe2O3 and Cu.
Cobalt, Nickel and Iron (as Fe2O3) Grades
The results of the analysis showed cobalt values averaging 0.11% (ranging from 0.01 – 0.49%) and nickel averaging 1.10% (ranging from 0.21 – 1.70%). The Fe2O3 for the 174 samples averaged 69.61% (from 6.75 – 80.18%)
The average of Co, Ni and Fe2O3 for the 174 samples is shown in the table below.
|All Samples||Min. Grade (%)||Max. Grade (%)||Wt. Ave. (%)||No. Samples|
Association of Cobalt, Nickel and Iron with Depth
In every location the samples were labeled with letter A to designate the lowest sample starting from the floor, B to designate the next sample above A and C to designate the sample above B. No physical or mineralogical differences in the laterite are apparent between these depths. Based on depth of sampling, cobalt grade is higher in A while nickel tends to be more evenly distributed. The average of Co, Ni and Fe2O3 for the 174 samples are shown in the table below.
|By Depth||Wt. Ave. % Co||Wt. Ave. % Ni||Wt. Ave. % Fe2O3||No. Samples|
Each sampling depth has its own characteristics in terms of Co, Ni and Fe content. A has the highest grades of Co and Ni but has a markedly lower Fe2O3 content compared to the B and C. In addition, C has lower Ni and Co content. The Co and Ni assays from C are below the global mean but has the highest Fe2O3 content, almost 74% which is 4% higher than the global mean. B on the other hand has a higher Ni and Co grade than the C but lower than A. However, B clearly has noticeable higher Fe2O3 content than A.
The results as described above indicate that cobalt and nickel are higher in the lower 2 meters of the deposit that were sampled in this program while Fe2O3 tends to be higher above it (above B).
It should be noted that not all A samples were taken from the base of the laterite. Out of the 66 locations, only 5 locations sampled the base of the laterite. Hence, higher cobalt and nickel grades may occur below the sampled sections.
Cobalt, Nickel and Iron in Different Blocks
In terms of cobalt content in the different blocks, the Eastern Block and the western side of the West Block have elevated values averaging 0.14% and 0.15% respectively (see linked map). The lowest cobalt assays are found in the smaller South Block (averaging 0.05%). The average of Co, Ni and Fe2O3 values for the different blocks are shown below.
|By Block||Wt. Ave. % Co||Wt. Ave. % Ni||Wt. Ave. % Fe2O3||No. Samples|
The sampling undertaken was limited to the accessible openings of the underground mine and by safety consideration issues and the complete laterite profile was not sampled.
The Company plans to conduct metallurgical tests in the following months to evaluate the metallurgical and mineral processing characteristics of the Skroska mineralization.
EVX Chief Executive Officer Fred Tejada notes, “We are very pleased of the assays that came out of our recent sampling in Skroska particularly that it covered a significant portion of underground workings that were either being developed or in production when operations stopped in the mine. Our aim in the next few months will be to understand the metallurgical and mineral processing characteristics of Skroska mineralization which is a big step ahead when compared with just looking to explore and find a cobalt-nickel deposit at this stage.”
About the Skroska Deposit
The Skroska deposit has a historic resource of 22.4 million tonnes of laterite grading 0.99% Ni, 49.13% Fe and 0.065% Co. The resource is historic in nature. The laterite deposit is estimated to range from 2 meters to 10 meters in thickness and to average approximately 6 meters thick. It occurs between footwall ultramafic rocks (serpentinized) and hanging or cap limestone. The limestone is a competent rock which makes it an excellent candidate for use as a natural roof for the open stope underground mining method employed in the mine historically and as maybe proposed for the future. Records indicate that approximately 1.15 million tonnes of laterite were mined between 1985-1990 (by the state-owned mining enterprise) and between 2008-2013 by Gerold (see also EVX news release dated October 11, 2018).
The tonnage and grade estimates stated above are historic in nature and were obtained from the records at the Albanian Geological Survey. The estimates done, using Russian deposit reporting system, are roughly equivalent to the National Instrument 43-101 inferred category. No qualified person (within the meaning of NI 43-101) has done sufficient work to classify the historical estimates as current mineral resources. EVX considers the historical estimates relevant in guiding exploration efforts and planning although EVX is not treating the historical estimates as current mineral resources. EVX will need to undertake a comprehensive review of available data, and to complete further drilling, to verify the historic estimates and to be able to classify them as current resources. There is no assurance that such verification or classification can or will be completed.
