High Grade Rare Earths Returned from Discovery Drill Hole: 4m at 1.84% TREO, including 1m at 3.87% TREO
-
Analysis of the 1m samples from the Mick Well discovery drill hole MWRC004 has returned 4m at 1.84% total rare earth oxides (TREO), including 1m at 3.87% TREO within the previously reported broader interval of 12m at 1.12% TREO.
-
The respective Nd and Pr values were 4m at 0.34% Nd2O3 and Pr6O11, including 1m at 0.7% Nd2O3 and Pr6O11 in fresh rock.
-
Mineralogy studies indicate the rare earth elements at Mick Well occur as allanite and monazite.
-
Follow-up drilling of the initial high-grade interval and other high-priority targets is scheduled for mid-April 2022.
-
Highly encouraging anomalous rare earth elements identified in historical diamond drilling in the west of the Company’s tenure, including 3.4m at 0.14% TREO.
-
The historical diamond drill hole is located approximately 25km along strike from Mick Well and highlights the potential of the 54km of strike of the target shear zones within the Company’s extensive tenure.
-
Field work currently underway, with mapping, rock chip sampling and ground-based radiometric surveys.
Kingfisher Mining Limited ( ASX:KFM ) (“ Kingfisher ” or the “ Company” ) is pleased to provide an update of the on-going exploration at its 100% owned projects in the Gascoyne Mineral Field in Western Australia.

The Company has received results from the 1m samples from the reverse circulation (RC) drilling completed at Mick Well last year. The 1m samples were selected from the interval from drill hole MWRC004 where rare earth elements (REE) mineralisation was previously reported from the 4m composite samples (see ASX:KFM announcement 10 January 2022). The results from analysis of the individual 1m samples include:
-
MWRC004: 4m at 1.84% TREO with 0.34% Nd2O3 and Pr6O11 from 41m, including 1m at 3.87% TREO with 0.70% Nd2O3 and Pr6O11 from 41m.
-
MWRC004: 1m at 2.39% TREO with 0.47% Nd2O3 and Pr6O11 from 49m (Figure 1).
The drilling program at Mick Well was designed to test targets that were identified from the Versatile Time Domain Electromagnetic (VTEM[TM] Max) airborne survey (see ASX:KFM announcement 10 January 2022). The MW2 target was also associated with a magnetic anomaly, with three-dimensional modelling of the magnetics data revealing the discrete magnetic low was a pipe-like feature with a significant vertical extent of 1000m. The pipe-like feature has now been interpreted to be associated with

The mineralisation at Mick Well is associated with carbonate complexes which consists of the carbonatite intrusions and dykes, amphibolite, gneiss and ultramafic rocks as well as alteration and veins related to the intrusions. The orientation of the mineralisation within this complex geological setting is not yet known, all reported intervals in this announcement are down hole lengths.

Kingfisher’s Executive Director and CEO James Farrell commented: “The analysis of the one metre samples from the rare earth discovery drill hole at Mick Well has revealed high-grade light rare earth elements within the previously reported interval. The Company has commenced mineralogy studies on the mineralisation which is now known to consist of the REE bearing minerals allanite and monazite.
Follow-up drilling has been scheduled to commence mid-April and will target the high-grade rare earth element mineralisation intersected in MWRC004 as well as a number of other high-priority targets in the immediate Mick Well Area”.

Mineralogy
Mineralogy and petrography studies by Richard England and Diamantina Laboratories on samples from the REE discovery at Mick Well are underway. Initial results from sample MWRC0312 (MWRC004, 41 to 42m, 3.87% TREO) which is located in fresh rock show the REE mineralisation occurs as allanite and monazite in rocks that dominantly consist of apatite, potassium feldspar, quartz and calcite (Figure 3).

Figure 3: Thin section showing >80% Allanite and monazite mineralisation from Mick Well drill hole MWRC004 (1m at 3.87% TREO).
Laboratory analysis for total rare earth content has been completed using Laser Ablation Inductively Coupled Plasma Mass Spectrometry and also by Inductively Coupled Plasma (ICP) Mass Spectrometry for all of the raw 1m drill samples that have been analysed. The laser ablation method used a lithium nitrate flux to form a fused bead in a furnace and is considered to have completely liberate all rare earth elements. The ICP method uses a four acid digest which may result in refractory minerals not being completely liberated. The results from both analytical methods are remarkably similar, highlighting that all rare earthbearing minerals have been completely liberated by the acid digest. The Company considers this to be an encouraging result as it highlights the potential for high recoveries of the Neodymium and Praseodymium.
Exploration Data Review – Application Tenements
Kingfisher has completed reviews of past exploration work completed on its new application tenements. During 1999 and 2000, Cameco Australia Pty Ltd (Cameco) explored an area which partially covers the western extents of the Company’s current tenure for unconformity-related uranium mineralisation. A diamond drill hole (GAD-0003) completed by Cameco intersected anomalous REEs, with 3.4m at 0.14% TREO from 2.6m downhole (WAMEX Report a61566). The drill hole is approximately 25km west of Mick Well and is in Kingfisher’s target shear zone for REE mineralisation – a shear zone which extends for 54km in the Company’s extensive exploration tenure (Figure 4). The anomalous REEs are associated with carbonates which were logged in the drill holes by Cameco. The Company considers the results to be extremely encouraging for the exploration potential of the entire structural corridor.

2022 Gascoyne Exploration Program
Kingfisher has planned extensive and targeted exploration programs for its Gascoyne projects for 2022. The planned exploration is designed to be cost-effective and aims to develop and test drill targets from ground-based work which will include mapping, rock sampling and radiometrics. The Company also plans to simultaneously develop a pipeline of exploration opportunities through integrating regional and airborne geophysical surveys with geological knowledge from the Company’s breakthrough REE discovery at Mick Well.
Activities completed Q1 2022 and planned activities for Q2 to Q4 2022 are shown below.

The Company has commenced fieldwork and has already completed sighter ground radiometric surveys and is continuing with geological mapping and rock chip sampling. The results from the on-going rock chip sampling were received by the Company with the 1m drill results and are yet to return significant rare earth element results. The field-based work is on-going and is currently targeting thorium and magnetic highs which are interpreted to be associated with the monazite mineralisation.
Drill programs have been planned for Mick Well, Kingfisher and Arthur River, with an initial follow-up program at Mick Well to commence early in Q2 and a larger program planned for Q3. The upcoming drill program will test five targets, including follow-up drilling at the MW2 and MW3 targets as well as another target which has a similar geophysical response as MW2, with a conductor identified from the VTEM Max[TM] survey and a coincident magnetic low (see ASX:KFM announcement 27 July 2021).

About the Kingfisher and Mick Well Projects
The Kingfisher and Mick Well Projects are located approximately 230km east of Carnarvon, in the Gascoyne region of Western Australia. The Company holds exploration licences covering 969km[2] and has recently increased its interests in the Gascoyne Mineral Field by nearly 40% through the targeted pegging of additional tenure interpreted to be prospective for rare earth elements (Figure 5). The tenure includes rocks of the Proterozoic Durlacher Suite that hosts the world-class Yangibana Deposit which includes 27.42Mt @ 0.97% TREO[# ] as well as the Archaean Halfway Gneiss.
Historic exploration at Mick Well was also focused on base metals associated with quartz reefs and gossanous ironstones which are up to 10m in width. Previous rock chip sampling in the area has shown results up to 10.6% Cu over a strike length of 1km within a laterally extensive geological horizon. Only four drill historical holes have been completed at Mick Well, with the best result being 11m @ 0.25% Cu from 118 m (MWDD001)[^] .
