Dundas Minerals Limited Announces Exploring for Nickel, Copper and Gold in the Prospective Albany-Fraser Orogen, Western Australia

Dundas Minerals Limited is actively exploring for nickel, copper and gold in the prospective Albany-Fraser Orogen, Western Australia. Dundas is pleased to provide an update on various exploration activities that commenced during December 2021. The in-fill ground gravity survey program which commenced 10 December 2021, is now complete. The survey was conducted on measurement stations at 100m intervals on 250m spaced lines. Final data has been delivered and it is expected that processing will be finalised early in the new year. The objective of this close-spaced survey is to provide gravity readings that will enable more precise modelling of the depth, three dimensional (3D) geometry, and the orientation of the dense under- cover bodies that were identified at Matilda South from the initial wide spaced gravity survey (500m station intervals on 1km spaced lines). Modelling of data from the initial survey has indicated dense bodies (gravity anomalies) that are at a depth commencing at approximately 130m below the surface, along a strike length of approximately 14km. Dundas's interpretation of the anomalies are that they are due to intrusive mafic or ultramafic rock types. These rock types are similar to the host rocks for the nearby Nova nickel deposit (150km north east of Matilda South). Drilling the modelled bodies is required to confirm this interpretation, and drilling will be planned for the first half of 2022. Of significance at Matilda South is a historic shallow air-core
drill hole DDHAC004 (31m), completed by Goldport Pty Ltd. in 2005.
The hole was logged as having an intersection of "intermediate /
mafic pluton or pyroxene granulite", this supports the interpretation
by Dundas of mafic or ultramafic rock. A multi-element geochemical soil sampling program commenced in December 2021 (Figure
3). The program is planned on a 250m by 250m grid with approximately 200 sample locations.
The objective of the program is to identify anomalous zones of mineralisation such as nickel,
copper or gold within the area. Geochemical soil anomalies were apparent at both the nearby
Nova nickel deposit (115km north-east) and the Tropicana gold deposit, in the northern
Albany-Fraser Orogen. The soil sampling program should be completed in mid-January 2022. A detailed ground gravity survey, similar to the program just completed at Matilda South, will
also be carried out at the North-East prospect. The survey is planned to start in early January
2022. Gravity readings will be taken at 100m intervals on 250m spaces lines and it is expected
that the survey will be take approximately two weeks to complete. Modelling of this data, plus
soil sampling and electro-magnetic data derived from the SkyTEM survey that was completed
by Dundas in August 2021, will be used for drill hole planning for a 2022 drilling campaign. Reverse Circulation (RC) drilling at the Company's Kokoda gold prospect commenced on 12
December 2021. Six (6) of the planned fifteen (15) drill holes were completed to 20
December 2021. The drilling and field services crews have now commenced their Christmas /
New Year break. Drilling is planned to re-commence during the first week of January 2022, initially
to complete the Kokoda program, and then drilling will move to the Jumbuck nickel prospect where
fifteen (15) RC drill holes are also planned. Drilling conditions have generally been favourable
and approximately one hole per day is expected upon the recommencement of drilling. Samples
from the first six drill holes have been dispatched, and results are expected to be received from
late February 2022.
