Lake Winn Resources Corp. Provides Exploration Update, Little Nahanni Lithium Project, Northwest Territories, Canada

January 26th, 2023

January 26th, 2023 – Vancouver, British Columbia – Lake Winn Resources Corp. (“Lake Winn” or the “Company”) (TSXV: LWR.H) (OTC: EQTXF) is pleased to provide an exploration update on our 100% owned Lithium Project, Little Nahanni Pegmatite Group (LNPG) at the Northwest Territory, Yukon border. The claims cover the majority of LNPG lithium, cesium, tantalum, tin (LCT) pegmatite vein swarm which extends over 13km of strike length. The property lies within 5km of a bulldozer trail and within 12km of an all-weather gravel road to Howard’s Pass.

Current Exploration

Lake Winn commenced exploration in late 2022 immediately upon funding (NR private placement timing). The most anticipated component of the current program is the magnetometer survey.

This is no ordinary magnetometer survey, Lake Winn has deployed DIAS Geophysical state of the art QMAGT system which uses a state of the art, SQUID (superconducting quantum interference device) sensor. The system measures the complete gradient tensor (second-order) of the earth’s magnetic field providing directional information about the magnetic field at an order of magnitude higher sensitivity, not available from total field sensors, which have been the industry standard for many years.

The SQUID sensors are developed by Supracon AG of Jena, Germany. Operating within a liquid helium bath, the result of over 20 years of development and testing and has now flown many successful exploration campaigns.

The vector magnetic data and ultra-high sensitivity was thought necessary to detect and map the LCT pegmatites at LNPG which, do not have a particularly strong magnetic response. The preliminary data just received, has striking linear magnetic responses, with one zone lining up with the known pegmatite trend (see Figure 1). and with a second stronger linear anomaly with no known geological explanation. Field crews will be deployed to investigate as soon as the snow clears. Based on the preliminary results the company staked additional ground to the east and south. The staking has been submitted to the NWT mines department and acceptance is awaited.

The project has 1,798m of historic drilling, the original drilling in 1997 as a tantalum project, did not assay for Lithium and this was corrected in 2016 when the core was re-assayed for Lithium. Results are given below in table 1. An extensive channel sampling program was also carried out at this time and the highlights of this program are shown in table 2. This demonstrates that the pegmatites carry world class lithium, tantalum and cesium mineralization. The task ahead is to find the zones along the 13 km of strike that could sustain economic mining.

In addition, to the SQUID magnetics, the Company’s current exploration focus uses the latest exploration tools. As part of this effort historic drill core was sent for scanning by GeologicAI. GeologicAI maps the core in fine detail utilizing optical, infrared and x-ray fluorescence (“XRF”). Scanning has been completed and the core returned to storage. Analysis of the data is awaited. The data from the historic core will be used train the AI to map and automatically log geology and mineralization during the Company’s planned summer drill program. The method should have the ability to map the lithium bearing spodumene and directly detect the tantalum and tin. Quantitative knowledge of the size distribution of the spodumene will directly aid metallurgy.

The company has commissioned Auracle Geospatial Science, Inc. to do a structural analysis. The dyke swarms are long and linear but have been disturbed by faulting during the mountain building process. Auracle’s 3D technology uses satellite radar and thermal data, but goes beyond INSAR’s and DiffInSAR’s remote satellite monitoring with proprietary methods that remove SAR’s typical noise and distortion to produce actual, not derived, 3D underground information. Lake Winn awaits the final report from this study by mid-February.

Lake Winn is working with Archer Cathro & Associates, to manage the exploration program. Archer Cathro has unparalleled experience in the Canadian North, with their partnership the Company has commenced permitting, and First Nation permissions in support of the planned summer drill program.

A desk-top engineering study, to bring road access to the project, has been commissioned and completed.

Mr. Buddy Doyle, exploration manager for the project commented:

“Our approach to this exciting project is to do everything we can prior to drilling. For this, we are utilizing the most modern and proven tools that were not available to past explorers. It also involves understanding the past work, and we are doing this with Archer Cathro, constructing a coherent data room.”

Current knowledge shows the property contains several semi-parallel dyke swarms up to 50m wide, with the swarm being made up of multiple pegmatite dykes from 0.2m to 10m wide separated by barren country rock. Lake Winn is focused on two target types for drill testing.

Target 1. Near surface open pittable target, where there is a vein thickening, in particular on structural bends where the geometry doubles. Investigating if optical machine sorting can easily separate the pegmatite from the country rock at the mining face might be a game changer for this project. Studies for separating the spodumene from the other materials of economic interest, tantalum, cesium and tin. In the early stage of the metallurgical process will also be investigated. The potential additional credits from these other elements that occur with the lithium have the potential to enhance the economics of the project.

Target 2. Conceptually the dyke swarms with many “fingers” of dykes are emanating out of a thicker more coherent “hand” at depth. This deeper body is a primary target for drilling. The dyke swarm is exposed on the mountain top but also along the cliff faces of the cirques demonstrating, along with the historic drilling with a greater than 300m extent. So far all the drilling has been at the top of the mountain, drilling at the base of the cirques will provide deeper access to look for the “hand.”

In 2007, War Eagle Mining drilled eight diamond holes (total 1798m) from six sites, together with a survey of the dyke system. This was aimed at testing dyke grade at depth and to see whether dykes tended to coalesce at lower elevation
