Additionally 100% of TREE's Sampled Contain High Levels of REE's
VANCOUVER, BC / ACCESSWIRE / March 7, 2023 / Spark Energy Minerals Inc., ("Spark" or the "Company") (CSE:EMIN)(Frankfurt:M1N)(OTC:MTEHF), has received from Foxfire Metals Pty Ltd, (Foxfire) its joint venture partner and manager of the Minas Gerais Lithium and REE project in Brazil, that the results of a soil and rock chip sampling program completed in December 2022 have been received from independent SGS laboratory in Brazil.
The Joint venture ground is located just 38km S.E. of Sigma Lithium tenements (TSX-V: SGML). in the "Lithium Valley" of Minas Gerais, Brazil.
The laboratory results confirm both Lithium and REEs present in the saprolite soils and altered granite/pegmatites associates with these soils.
All soil samples were collected over 13 different areas within the 3500 Hectares of Joint Venture ground and indicate the presence of Lithium and REE (rare earth element) mineralisation.
Highlights:
Lithium (Li):
Li (see table 1) confirmed in 90% of the samples of the analyzed saprolite soils: -
- Up to 154 ppm Lithium reported in surface soil samples.
- Pegmatites and altered granites were confirmed in the rock chips analyzed and contain Lithium mineralization.
Rare Earth Elements (REE):
Every sample (100%) analyzed contains REEs with 16 of the 17 TREE elements confirmed.
- average TREE of ~2055 ppm over selected samples.
- highest individual sample (PMG2) recorded TREE of ~3050 ppm.
- Average TREE used in magnets 25.5%.
- Light REE: 86% average of total REE
- Heavy REE: 14% average of total REE
Mineralized zones:
Confirm mineralization for Lithium and REEs in at least 13 locations over the 3,500 hectares JV ground.
Geological structures:
Mapping identified several structures for hosting potential mineralization.
Plans moving forward:
June 2023 Quarter
- Planned Auger drilling for next quarter to further test for Li and REE in the saprolite soils and oxidized pegmatite and granite.
- A geochemical and geophysical work program to identify primary ore drilling targets planned in the June 2023 quarter.
As previously reported, Foxfire completed a geochemical and mapping program in December 2022. Soil and rock chip samples collected were sent to SGS laboratory in Brazil to analyse for Lithium and Rare Earth Elements (REEs). These samples were collected from thirteen locations over the 3500 hectares JV licenses.
Every location that was sampled indicated lithologies (Saprolite soils and altered pegmatites and granites) containing Li and REE mineralisation.
The SGS laboratory results confirmed the presence of Lithium and Rare Earth Elements (REE) in the saprolite soils tested. Lithium was found in 90% of the samples analysed and REEs were found in all the samples analysed with 16 of the 17 TREE groups present.
Old workings are present on one of the 3 licenses and have confirmed previous mining activities.
The samples were prepared and analysed by SGS laboratories in Brazil and confirm Lithium and REE mineralisation in the saprolite soils and altered pegmatites and granites.
90% of the lithium in the saprolite soils contain up to 154ppm Lithium and 100% of the rock chips sampled contained lithium.
100% of the samples contain REEs in the saprolite soil and in the rock chip samples with the highest TREE (total Rare Earth Elements) sample PMG2 containing ~3050 ppm REE.
A further geochemical soil program and geophysics - airborne radiometric program is scheduled to commence in the next quarter with the objective of identifying drill targets focused on intercepting the primary zone of potential mineralisation for Lithium and Rare earths (REE).
A shallow auger drill program to test the extent of the mineralisation in the soils is also planned to commence in the next quarter.

Location Map: Inset 1
These Three lithium licenses lie within the highly prospective northern portion of the state of Minas Gerais in the municipality of Padre Paraiso -the location of the Brazilian lithium producing districts and lithium belt. The areas are known to host lithium bearing pegmatites associated with spodumene, lepidolite, and amblygonite.
