Plutonic Gold Belt, Western Australia - Numerous High-Grade gold intercepts from Trident drilling program

06.09.2023 | CNW

Plutonic Gold Belt, Western Australia - Numerous High-Grade gold intercepts from Trident drilling program

High-grade results, incl. 9m @ 64 g/t and 9m @ 33 g/t Au

Results fill gaps within Trident Mineral Resource, providing a strong basis for Definitive Feasibility Study (DFS)

Key Points

40 drill holes have been completed, infilling various gaps in the Trident Mineral Resource
Initial results from these holes report significant intersections, with further results to be released as available
Results will be used to update the Trident Mineral Resource as part of the ongoing Trident DFS
Recent Trident Scoping Study demonstrated potential for high grade (6.7 g/t head grade), low AISC (A$1,046/oz) and low capital intensity (preproduction capital of A$36m) project
Trident DFS due in CY 2024

, Sept. 5, 2023 /CNW/ - Catalyst Metals Ltd. (Catalyst) (ASX: CYL) is pleased to announce it has received the first batch of results from a Mineral Resource infill drilling campaign at Trident.

The drilling program will provide important data to support Catalyst's Definitive Feasibility Study of Trident.

Catalyst's MD/CEO, James Champion de Crespigny, said: "This infill drilling program at Trident is an important step for Catalyst to progress the Trident DFS. One might describe this drilling as comfort drilling - there were gaps within the Trident Resource where Catalyst preferred to have closer spaced drilling. This infill drilling closes those gaps, giving greater comfort to the Mineral Resource and ultimately the DFS."

Drilling highlights:

14m @ 2.550 g/t Au (from 144m)
3m @ 4.270 g/t Au (170m)
9m @ 3.260 g/t Au (177m)
8m @ 10.050 g/t Au (190m)
9m @ 33.310 g/t Au (155m)

12m @ 6.1 g/t Au From (139m)
7m @ 4.6 g/t Au From (149m)
12m @ 12.89 g/t Au (149m)
9m @ 64.39 g/t Au (180m)

Summary of Drilling Program

During July, drilling contractors were mobilised at the Trident deposit to complete a reverse circulation (RC) and diamond drilling program (RC collars with diamond tails), targeting priority areas in the known mineralisation.

The objective of the program was to improve the density of drill coverage within the Trident Mineral Resource.

The drilling results will also be used for further metallurgical testing and geotechnical assessment as part of the DFS.

The drill results are in areas where the mineralisation was estimated to be very high grade. However, the drill density was low. In these important parts of the Resource, closer spaced drilling was important. The fact that these intercepts are returning high-grade results, and as such confirming the continuity of this high-grade mineralisation, is very encouraging.

TDR0050: Example of infill drilling closing a gap in Trident Resource model. Note the continuation of high-grade zones within the gap, increasing the confidence in the drill data upon which the Resource is based.

Catalyst has reviewed drillhole data made available through the acquisition of the Vango Mining tenure, and applied the previous verification performed by Vango technical personnel. Vango Mining had announced on 4 April 2017 and 2 May 2017 results of their data review including contributions from Resolute Mining (ASX: RSG - 1997), Homestake Mining (2000), and Dampier Gold (ASX: DAU - 2011).

Trident Deposit & Scoping Study

The Trident deposit is located on existing mining leases, approximately 25km north-east of the Plutonic gold mine. An existing, well maintained haul road connects Trident to the Plutonic mill.

Trident hosts an Indicated Mineral Resource of 945kt at 9.4g/t Au for 285koz Au¹ and an Inferred Mineral Resource of 645kt at 6g/t Au for 125koz Au. Catalyst recently released the results of a Scoping Study at Trident which utilised a 230koz of the 410koz Mineral Resource. This study demonstrated the potential for strong cashflows with low upfront development capital. Catalyst has commenced a DFS, which the results of the drilling program will support.

The details of the scoping study are below.

JORC 2012 Edition, Table 1 Checklist Diamond Drilling

Diamond Core Sampling
Techniques and Data

Criteria

Explanation

Aspects of previous exploration (Homestake Mining, Dampier Gold) were
verified and reported to ASX by Vango Mining (4 April 2017, 2 May 2019)

Sampling techniques

All 2023 RC pre-collars were sampled as either 4-metre composites or 1-
metre samples beneath the granite contact. RC samples were riffle split to
3kg for submission to an external laboratory.
Previous RC drilling was sampled as 1m intervals.
2023 Diamond core was cleaned and sampled as 1-metre intervals.
2023 Diamond core was either sampled as cut half-core or sampled in
entirety when project scheduling requires expeditious data turnaround.
Previous explorers sampled drill core as variable intervals to 1m maximum.

Drilling techniques

All 2023 holes were pre-collared using 5.5" RC hammer. At end-of-
precollar depth, the rod string was removed from the hole and steel HQ
casing is installed and shoed into the base-of-hole. NQ triple tube barrel
and NQ drill rods were installed to precollar depth. Beyond this depth the
holes were drilled to final depth with DDH drilling techniques, generally
employing three-metre barrel and rods. Where ground conditions were
poor, 1.5-metre runs were employed to alleviate core loss during tube
extraction.
Previous explorers drilled using RC hammer or NQ diamond drilling

Drill sample recovery

2023 Core runs were documented by the driller, and recoveries measured
by the geologist/assistants to ensure recovery was known and strategies
implemented to maximise recovery (target being above 90%). Drillers
were under instruction to monitor recovery and rectify core loss through
adjusting drill rig operation. All diamond core was drilled using triple tube
equipment to assist in delivering acceptable core recovery.
No information available for previous explorers

Logging

2023 Diamond core was geologically logged for lithology, alteration,
sulphide mineralisation to a standard acceptable for subsequent
interpretation for use in estimation. Geological logging aspects were
qualitative with exception of sulphide content which was estimated semi-
quantitatively. Drill core structural measurements were logged prior to
cutting/sampling. Drill core orientations were performed on each core
run, and where successful were applied to structural measurements to
provide known orientations of structures.
No information available for previous explorers

Sub-sampling techniques and
sample preparation

2023 Lab submission samples collected as described above. No quarter
coring was routinely required. Samples dispatched to commercial assay
laboratory (Catalyst have used ALS Pty Ltd exclusively); samples crushed,
dried, and pulverised in entirety, with 50g charges selected for analysis
(laboratory repeat splits historically demonstrate acceptable
reproducibility and hence accuracy for this style of mineralisation)
Dampier gold exploration samples were assayed by an unknown
laboratory. Assays were performed on 50g fire assay charges.
Homestake Mining exploration samples were assayed by Amdel
(contractor). Assays were performed on 50g fire assay charges.

Diamond Core Sampling Techniques and Data Criteria	Explanation Aspects of previous exploration (Homestake Mining, Dampier Gold) were verified and reported to ASX by Vango Mining (4 April 2017, 2 May 2019)
Quality of assay data and laboratory tests	2023 Gold assay determined by AAS via 50g fire assay (ALS code Au-AA26). Duplicate analysis has shown this method to be appropriate for fine grained and well disseminated gold population of the mineralisation. Laboratory and client certified reference materials (standards) were implemented every 20^th sample. Performances outside 2 standard deviations as per specification would be reviewed with the laboratory, and 3 standard deviations default to a re-assay. No such errors were encountered. Previous explorers employed 50g fire assay for gold determination.
Verification of sampling and assaying	2023 Data management procedures are in place. Data management has been outsourced to a specialist provider. There has been no verification of significant intersections by independent nor alternative company personnel. Drillhole sampling and geological data logged electronically and imported electronically into the master database. There have been no adjustments to data as provided by the commercial assay laboratory. Verification performed by previous explorers is unknown.
Location of data points	All 2023 drillhole location coordinates are measured using differential GPS to MGA94 Zone 52. Collar locations to within an estimated precision of 10mm horizontally and 20mm vertically. All drillholes are downhole surveyed by gyroscopic instrument. Drilling orientation established prior to collaring with clinometer and compass.
Data spacing and distribution	Diamond drillholes drilled at a section spacing of approximately 40 - 50 metres to provide for infill coverage down to 25m. This spacing is designed to be of a sufficient density to ultimately be included in resource estimation. For the purpose of the reporting of exploration results, assays are aggregated to reflect continuously sampled zones of significant anomalism for gold. Dampier Gold employed a 40m grid spacing for drilling, which formed the basis for subsequent 2023 infill drilling pattern.
Orientation of data in relation to geological structure	Drillhole sections were aligned approximately 90 degrees from the strike of mineralisation. Holes were generally inclined 55 - 75 degrees to the south to provide cross-strike investigation within holes and to establish continuity of north-dipping mineralisation. Similar orientations are apparent for previous explorers.
Sample security	All 2023 samples were controlled by the responsible geologist and stored in secured facility prior to despatch to the laboratory. Samples were transported directly to laboratory by a commercial transportation contractor with security in place. Sample number receipt information from laboratory cross-referenced and rationalised against sample number dispatch information. Previous explorers employed unknown security measures.
Audits or reviews	No processes or data used in developing the release of 2023 exploration results have been subject to audit or review by non-company personnel or contractors to reduce costs and timelines for reporting. Catalyst Metals Limited currently reserve this process for release of Mineral Resource and Ore Reserve statements. Previous explorers employed unknown levels of audit and review.

Reporting of Exploration Results

Criteria

Explanation

Aspects of previous exploration (Homestake Mining, Dampier Gold) were
verified and reported to ASX by Vango Mining (4 April 2017, 2 May 2019)

Mineral tenement and land
tenure status

The Trident project is within mining lease M52/217 25km to the northeast
of the Plutonic Gold Mine, Western Australia. The lease is held by Vango
Mining Pty Ltd, a 100% subsidiary of Catalyst Metals Ltd.
(ASX:CYL)M52/217 is in good standing, and due for expiry on 19/03/2033,
and covers 913.1 ha. This lease is located on freehold grazing pasture.

Exploration done by other
parties

Previous drilling has been extensive and completed by Resolute Mining
(1997), Homestake (2000), Dampier Gold NL (2011)

Geology

Gold mineralisation is hosted within a shear zone within ultramafic rock.
The high-grade core of mineralisation associated with a steepening and
thickening of the mineralised zone within the host shear zone - referred to
as a 'ramp'

Drillhole Information

Appendix 1, Table 1a: Collar location coordinates, downhole depths,
azimuths, declinations
Appendix 1, Table 1b: Downhole intervals of resource, gold grade of
intervals

Data aggregation methods

No top-cutting was applied to assay data. Zones of significance were
identified as those with assays in excess of 1ppm and internal dilution of
three consecutive metres or less. Reported zones are continuous, with no
sample or assay gaps.

Relationship between
mineralisation widths and
intercept lengths

The strike of mineralisation is demonstrated to be generally 60 degrees
east of north (MGA94 Zone 52 grid). The dip of mineralisation is expected
to be variably north-west-dipping with two generalised domains
demonstrating a 30-degree dip and a sub-vertical dip.
Diamond drillholes were oriented with a dip to the south (rotated local
grid) to provide effective geometry with respect the described geometry of
mineralisation.
Due to the complexity of geometry of the gold mineralisation, the true
width of mineralisation has not been resolved. As such, significant
mineralised intersections have been reported as downhole intervals.

Balanced reporting

Table 1b shows all 2023 drilling including those that did not demonstrate
significant gold intercepts.

Other substantive exploration
data

No other exploration results that have not previously been reported, are
material to this report.

Further work

Deep diamond drilling will continue through to further delineate identified
mineralisation
