MANONO TAILINGS MINERAL RESOURCE STATEMENT
The Mineral Useful resource was estimated utilizing the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Finest Observe Tips and is reported in accordance with the 2014 CIM Definition Requirements, which have been integrated by reference into Nationwide Instrument 43-101 – Requirements of Disclosure for Mineral Tasks (NI 43-101).
A abstract of the Mineral Useful resource estimates per deposit in addition to the full Measured, Indicated and Inferred Mineral Sources is proven in Desk 1.
The Mineral Useful resource is classed into the Measured, Indicated and Inferred classes and is reported at a cut-off grade of 0.20% lithium oxide (Li2O). The cut-off grade and cheap prospects for eventual financial extraction (RPEEE) had been decided utilizing the next assumptions:
- Mining will probably be undertaken utilizing bulldozers and loaders.
- Mining price: USD 2.17 per tonne of rock
- Mining Restoration: 99%
- Processing price: USD 11.18 per tonne processed (RoM)
- Income Royalty: 3%
- Payability: 98.5%
- Course of Restoration LiO: 50% to 70%
- Lithium Worth: 4 000 USD/tonne (SC6 – Spodumene Focus)
The evaluation to fulfill the standards of RPEEE is a high-level estimate and isn’t an try and estimate Mineral Reserves.
Eric Allard, President and CEO commented: ‘’ With this Mineral Useful resource Estimate, Tantalex Lithium now enters a choose group of near-term lithium producers. Our comparatively simple and low-cost mining course of provides us an unbelievable benefit on our pace to market in comparison with different lithium friends.
With SC6 lithium costs possible set to stay above $4,000 USD/t for the following 6-8 years, our focus is now to deliver an preliminary manufacturing of 100,000 tons each year of SC6 to market by 2025. With no offtake agreements but entered into, our challenge is at present attracting vital offtaker curiosity.’’
Determine 1: Licence Boundary of PER 13698 and Tailings areas
The Manono Tailings Challenge consists of 11 technogenic deposits made up of the reject LCT (Lithium-Caesium-Tantalum) pegmatite materials processed on the Manono-Kitotolo mine from 1919 to the mid-Nineteen Eighties.
Tailings from the Manono-Kitotolo mine had been deposited on floor adjoining to the varied open pits. The coarse tailings had been deposited over a number of years into raised heaps that attain, in some dumps, a most top of 70 m above floor. The tremendous tailings materials was deposited into flat terraces adjoining to the coarse tailings dumps.
Geology and Mineralization
The lithium mineralization is contained inside technogenic deposits, consisting of 11 particular person tailings dumps, of which 5 kind half the Mineral Useful resource, specifically Cc, Ic, Gc, Gf and Okay. The tailings deposits encompass a mixture of processed pegmatite, laterite and clay materials sourced from the historic Manono-Kitolo mine which operated from 1919 to the mid-Nineteen Eighties. The deposits fluctuate in form and dimension, with Cc, Ic and Gc being lobate in form, extending 815 m by 580 m for the Cc dump, 530 m by 315 m for the Ic dump and 500 m by 320 m for the Gc dump. The peak of every dump varies, with some stacked as much as 78 m excessive above the encompassing planes. The Gf and Okay dumps occupy a bigger footprint, with the Gf extending 760 m by 530 m, as much as a most thickness of 33m, whereas the Okay dump has an extent of 700 m by 630 m, as much as a most depth of 24 m. The Okay dump incorporates stacked tailings positioned within the northeast and japanese parts with a most vertical thickness of 45 m. Spodumene is the principle lithium bearing mineral.
Lots of the tailings deposits are composite in nature, consisting of layers of pegmatite, laterite and/or clay layers. These layers had been deposited by mechanical means, together with many of the deposits denoted as “fines”, for the exception of the Hf and Gf deposits. These are assumed to have shaped because of the settling of tremendous materials in standing ponds of water as evidenced by the presence of clay layers in these deposits.

Few deposits seem to encompass a single materials sort, the exception to this being the Okay dump which is primarily composed of pegmatite. Determine 3 exhibits the white, pegmatite tailings and the partially vegetated cone-like function of the stacked Okay dump tailings, wanting south.

Sampling and Mineral Useful resource estimation strategies
The Mineral Useful resource estimate was based mostly on geochemical analyses of samples obtained by aircore drilling undertaken by Tantalex from September 2021 to July 2022. A complete of 368 drillholes have been drilled throughout 9 tailings deposits, totaling 11 922.24 metres of drilling. Nearly all of the drillholes had been collared on the Okay dump, with 2 120 metres drilled from 156 drillholes. Fifty drillholes had been collared on the Gf dump, 34 on the Ic dump, 25 on the Gc dump and 20 drillholes had been collared on the Ic dump.
Because of the nature and angle of repose of the stacked tailings, drilling on the slopes was not doable. Therefore a majority of the fabric within the slopes has been included within the inferred class.
Samples had been taken in a single metre intervals and composited to a few metres. Three pattern preparation protocols had been used throughout the drilling marketing campaign. The primary protocol was used early within the programme and concerned crushing the pattern all the way down to 2 mm utilizing a roll crusher, after which a 200 g sub-sample was obtained from a Jones Riffle splitter. This 200 g pattern was then sub-sampled by the cone-and-quartering methodology to acquire a 100 g pattern which was pulverised to raised than 80% passing 75 μm. The crushing, splitting and pulverising had been carried out on-site by Tantalex. The second pattern preparation protocol concerned the crushed 200 g sub-sample being ready on-site after which transported to the Congolese Analytical Laboratory (COAL) in Lubumbashi the place the sub-sample was pulverised to 85% passing 75 μm. For the third protocol within the latter a part of the challenge, 400 g of pattern had been submitted to COAL the place it was crushed to a 2 mm dimension fraction utilizing a benchtop jaw crusher after which pulverised to 85% passing 75 μm.
The samples had been subjected to a top quality assurance and management (QAQC) programme consisting of the insertion of licensed reference supplies (CRMs), blanks and the inclusion of coarse duplicates. The first laboratory assay outcomes had been confirmed by duplicate samples assayed at a second laboratory. Examine samples chosen by the QP had been used for additional affirmation of the lithium assay values and the QP is happy that the outcomes are of ample accuracy and precision to be used in Mineral Useful resource estimation.
Three-dimensional volumes of the tailings had been constructed utilizing drill gap information. The lithium grades had been estimated into block fashions utilizing bizarre kriging for the low-lying materials of the Okay dump. The stacked materials of the Okay dump and the Cc, Gc, Gf and Ic dumps had been estimated utilizing inverse distance weighting. Common densities had been assigned to every materials sort.
Metallurgical Testing
A abstract of the HLS outcomes is accessible in 2. The HLS take a look at produced focus grades of 6.5% Li2O spodumene at total recoveries throughout the scale vary of 47% and 63% for G-dump and Okay-dump respectively. The testwork didn’t produce a SC6 product from the C-dump this requiring additional investigation. These outcomes are for all of the dump materials with a PSD smaller than 5mm.
The lithium recoveries elevated with dimension fraction whereas the tin and tantalum required additional liberation to enhance recoveries.
