Kingwest Resources Limited ("Kingwest" or "KWR") is pleased to announce updated Mineral Resource Estimate's (MRE's) for the Pericles, Lady Shenton and Stirling deposits at the Menzies Gold Project (MGP) (Figure 1). These were based on additional RC drilling completed in 2021 that was not included in previous MRE's. New drill intersections included 26m @ 4.56 g/t Au from 158m, including 2m @ 49.49 g/t Au from 169m in KWR2771 and 19m @ 2.15 g/t Au from 167m in KWR2741.
The MGP is located approximately 130km north of Kalgoorlie and is well serviced by infrastructure and within trucking distances of numerous treatment plants.
The new estimates are presented in the Table 1 below using 0.5g/t Au cut offs except for Yunndaga which includes some Inferred resources above a 2.0g/t Au cut off at greater depths.

Kingwest CEO Ed Turner commented that "We are very pleased to continue to increase our near surface gold resources at Menzies, particularly with Pericles increasing by 34,000oz at a discovery cost of only $5/oz. The potential to continue to grow these resources with further extensional drilling is high. It is important to note that these MRE's are constrained by depths that are likely to be captured within open cut mining. Kingwest continues to investigate the best options to develop and/or commercialise these significant resources."

1. Introduction and Background
Cube Consulting (Cube) was engaged by Kingwest Resources Limited (KWR) to update the Mineral Resource Estimate (MRE) for the Lady Shenton, Pericles and Stirling deposits. This was based on additional drilling completed at the project by KWR since the previous MRE's in March 20212.
2. Data
For the April 2022 MRE updates, Cube was provided with an updated database which included recent drilling completed at the project area. The database included 56 additional RC drillholes: KWR212 to KWR286 used directly within the updated MRE's.
The final grade estimate was based on:
694 RC holes
17 RC pre-collar holes with diamond tail
2 diamond holes
476 RC grade control holes within the pit area
No other new additional data was included and all information relating to the March 2021 MRE was included in the April 2022 update.
3. Geology and Interpretation
3.1. Weathering
Weathering interpretations were completed by KWR during the March 2021 MRE process and supplied to Cube as wireframe solids created in Leapfrog software. These interpretations were reviewed with respect to the recent drilling and no modifications have been made. The majority of recent drilling has targeted deeper extensions to mineralisation and therefore not materially affected the weathering surfaces.
The weathering interpretation included three solids representing oxide, transitional and fresh material.
3.2. Lithology
Lithology interpretations were completed by KWR during the March 2021 MRE process and supplied to Cube as wireframe solids created in Leapfrog software. These interpretations were reviewed with respect to the recent drilling and no modifications have been made.
3.3. Mineralisation
The mineralised domains were updated based on the previous March 2021 MRE interpretations and edited to account for the recent drilling. The final domain wireframes acted as hard boundaries during the grade estimation.
The mineralisation interpretation process was guided by the following criteria from drill hole assaying and logging, and other information provided from the historical data and documentation:
Cube reviewed the digital database for gold and geological logging to identify any correlation between lithology/alteration/veining logged and gold mineralisation.
Previous gold mineralisation interpretations were used as a guide for updating and developing the main mineralisation domains and trends used to develop the updated estimation model.
Mineralisation interpretations were usually completed on section and then revised in plan. The interpretations were generally modelled on a nominal 0.3 g/t Au mineralisation envelope which appears to be a natural cut-off and provides sufficient continuity.

Interpretations were generally extended half the drillhole spacing past the last intersection. No minimum intersection length criteria was used but typically the intersections were greater than 2m but did included minor 1m intersections for continuity of interpretation.
All final 3DM domains were validated to ensure wireframe integrity and continuity for later volume checks with the block model.
The mineralised downhole intervals were coded into the drilling database and boundary snapping checked/amended in 3D software (Surpac).
The samples contained within the domains were then composited and plotted for later exploratory data analysis (basic statistics) and spatial data analysis (variography and KNA), prior to block model construction and grade interpolation.
Table 2 below compares the mineralisation domain volumes from March 2021 to April 2022. The key differences include:
Significant interpreted volume increases for the Lady Shenton domains 401 and 405 and to a lesser degree 402. The extensions are due to new drilling down dip and along strike to the southeast.
Significant interpreted volume increase for the Pericles domain 501 and to a much lesser degree 502 to 504. The main extension to domain 501 is due to new drilling down dip and along strike to the southeast.
Significant interpreted volume increases for almost all Stirling domains, especially 601 and 607. In addition, 3 new domains have been interpreted. Most of the new drilling at Stirling has been infill and down dip of the previously known mineralisation extents.
