GASCOYNE MINERAL FIELD
KINGFISHER MINING
COMPANY PROJECTS
The Company’s breakthrough Mick Well REE discovery occurs within the crustal-scale Chalba Shear Zone which extends over a strike length of 54km within the Company’s tenure. On-going exploration by the Company in the area has also identified a second, large-scale REE target at the LK1 Prospect. These exciting targets are prospective for carbonatite REE mineralisation similar to Hastings Technology Metals’ world-class Yangibana Deposit which includes 29.93Mt at 0.93% TREO as well as the recent Yin and C3 discoveries of Dreadnought Resources which include mineral resources of 40.82Mt at 1.03% TREO².
The Company’s Gascoyne tenure is also prospective for lithium-bearing Thirty Three Suite Pegmatites, with the Company identifying strike length of more than 13km of outcropping pegmatites with rock chip results up to 0.61% Li₂O. The Thirty Three Suite Pegmatites are also the host Delta Lithium’s Yinnetharra Project which is located 40km northeast of Chalby Chalby and has a mineral resource of 25.7Mt at 1.0% Li₂O.
The Company’s projects are located approximately 230km east of Carnarvon.

MICK WELL REE PROJECT
Mick Well occurs within a large-scale carbonatite intrusion centre that extends over an area of 10km by 7km. The Company has mapped more than 20km of strike of high-grade REE mineralisation in dykes and veins that are associated with three pipe-like features which have been delineated from geophysical surveys. Each of the large pips targets is more than 1,000m in diameter and close to the ground surface.
High grade discoveries of REE mineralisation have been made by the Company at the MW2, MW7, MW8, MW9, MW10, MW11, MW12, MW13 and MW14 Prospects. The REE mineralisation dominantly occurs as monazite and is associated with ferrocarbonatite intrusions and exceptionally high-grade veins that fill structures around the modelled carbonatite intrusion centres. Drilling at MW2 has returned the following highly encouraging results:
-
MWRC011: 5m at 3.45% TREO with 0.65% Nd₂O₃ + Pr₆O₁₁ from 102m, including 3m at 5.21% TREO with 0.98% Nd₂O₃ + Pr₆O₁₁ from 102m.
-
MWRC033: 3m at 2.52% TREO with 0.41% Nd₂O₃ + Pr₆O₁₁ from 46m.
-
MWRC035: 4m at 3.24% TREO with 0.54% Nd₂O₃ + Pr₆O₁₁ from 46m.
-
MWRC059: 4m at 1.90% TREO with 0.34% Nd₂O₃ + Pr₆O₁₁ from 65m, including 3m at 2.42% TREO with 0.43% Nd₂O₃ + Pr₆O₁₁ from 65m.
-
MWRC067: 5m at 2.63% TREO with 0.54% Nd₂O₃ + Pr₆O₁₁ from 124m, including 3m at 4.11% TREO with 0.85% Nd₂O₃ + Pr₆O₁₁ from 124m.
-
MWRC068: 5m at 1.54% TREO with 0.30% Nd₂O₃ + Pr₆O₁₁ from 75m.

MICK WELL CLAY-HOSTED REE MINERALISATION
A second style of REE mineralisation also occurs at Mick Well, with REE mineralisation hosted in kaolinite clays and weathered bedrock that occur from surface within the broad shears which are part of the extensive Chalba Shear Zone. Geological interpretation of the shear zone and associated clay mineralisation at Mick Well has highlighted a potential strike length of 6.5km and drilling has delineated widths of 100m with vertical extents to 40m depth from surface. Significant drilling results from the clay mineralisation at Mick Well include:
-
MWRC020: 48m at 1265 ppm TREO with 257 ppm Nd₂O₃ + Pr₆O₁₁ from 4m, including 40m at 1367 ppm TREO with 278 ppm Nd₂O₃ + Pr₆O₁₁ from 8m.
-
MWRC021: 16m at 1156 ppm TREO with 228 ppm Nd₂O₃ + Pr₆O₁₁ from 8m, including 12m at 1301 ppm TREO with 259 ppm Nd₂O₃ + Pr₆O₁₁ from 8m.
-
MWRC027: 36m at 779 ppm TREO with 164 ppm Nd₂O₃ + Pr₆O₁₁ from 4m.
-
MWRC028: 48m at 1076 ppm TREO with 204 ppm Nd₂O₃ + Pr₆O₁₁, including 16m at 1580 ppm TREO with 325 ppm Nd₂O₃ + Pr₆O₁₁ from surface.
