Raleigh Lake Project
The Raleigh Lake Project consists of spodumene bearing lithium pegmatites located in Ontario, Canada. The region is host to several lithium occurrences, including the Company’s Mavis Lake joint venture project. The area exhibits excellent infrastructure that includes sealed roads, rail service and electric power. The project is in close proximity to other mining projects, towns and the port city of Thunder Bay offering a skilled labour force and excellent mining related services. The Raleigh Lake Project is owned 100% by ILC, with no underlying royalties
The Project is located approximately 25 kilometres west of Ignace and 235 kilometres west of Thunder Bay, ON. It is easily accessed by a well-maintained logging roads that branch south from Highway 17 (Trans-Canada Highway) along the Doreen Lake road.
The Raleigh Lake project is ideally located adjacent to the Trans Canada Highway. Rail and electrical power infrastructure is also in close proximity to the project making an ideal scenario for an industrial mineral mining operation.
Raleigh Lake Claims
The Raleigh Lake Project claims cover approximately 3027 hectares. The Raleigh Lake Project is owned 100% by ILC, with no underlying royalties
Mineralization at Raleigh Lake
Pegmatites and corresponding lithium, and cesium/rubidium mineralization trends were identified in 1999 by a previous operator searching for tantalum mineralization.
Geology and Pegmatite Emplacement at Raleigh Lake
The “Two Mica Granite” (13) is thought to be the source of the lithium-cesium-tantalum (LCT) pegmatites at Raleigh Lake.
Mineralization Emplacement Model
analysis of regional gravity and magnetic surveys shows trans-tensional
faulting is extensive at Raleigh Lake.
faulting provides the structural conduits to transport lithium bearing magma
and creates space to form large pegmatite intrusions.
- The circled area is known
mineralization defined by previous operators.
- It is approximately 600m x 400m and
underlain by shallow dipping and flat lying pegmatites rich in tantalum and
- The coloured dots are lithium values
in lithogeochemical samples.
Cross Section NW-SE
- The stacked pegmatites gently dip below the
surface and flatten out at depth.
- The number and thickness of the pegmatites
appears to increase toward the southeast (SE).
The results presented here were derived from publicly available assessment reports written by previous operators on the Raleigh Lake project. The reports appear to have been prepared by Qualified Persons as defined by National Instrument 43-101, but no Qualified Person has verified these results on behalf of International Litihum Corp. The reader is cautioned that the results achieved by International Lithium Corp. may not replicate these results. The intercepts reported appear to be drill hole intercepts and not the true width of the mineralized zones with true width presently unknown.
The flat lying nature and zonation of the pegmatites at Raleigh Lake bears a resemblance to the Tanco pegmatite at Bernic Lake.
- Discovered in 1929 completely hidden under Bernic Lake, Manitoba
- Consists of a sub-horizontal body 1.5 km x 1 km and up to 100m thick.
- Mined since 1967
- Global role in the production of Ta, Cs & Li
- Mineralization is increasing in direction of the magnetic anomaly
- Structures define interpreted mineralized conduits
- Geochemistry defines mineralized conduits
- Magnetics define structural traps and expansion zones that can host large fractionated
pegmatites similar to Tanco
Comparing Raleigh Lake to Tanco
In February 2010, P. Vanstone of Vanstone Geological services and former Chief Geologist at Cabot Corporation’s Tanco Mine was commissioned by Abaddon to conduct a property and diamond drill core review. Key comments from his report confirm that the pegmatite fractionation trends [at Raleigh Lake] are towards the southeast. Additionally, there is a prominent gabbroic hosting body encapsulating pegmatite #1, and this information, along with sheared contact relationships caused by reactivated structural features, multiple pegmatite phases insinuates a complex pegmatite emplacement history that adds exceptional value to the Project and its potential to host a significant pegmatite body (Vanstone, 2010).
Plans for 2020
For the reasons described above, ILC considers Raleigh Lake to be a potentially extremely promising property. However it is in the nature of mining exploration that further validation is required to prove whether or not a deposit really is major, and until proven there is always a risk that it will not in fact be as promising as it may appear. To this end ILC intends carrying out exploration in 2020 to try to validate the potential with the intention to drill a further 20 or more holes on the enlarged property, having conducted further magnetic surveys on the enlarged mineral claims in 2019. This is a key use of funds in a fundraising being carried out in 2020.
