• 76.2m @ 8.62g/t Au inc. 23.5m @ 21.8g/t Au in drill hole CM23-08[4]

Commenting on the results, Managing Director, Stephen Baghdadi, commented:

“The wide intersection in drill hole CM23-14, that includes a higher grade zone, is consistent with other drill holes that have been completed.

“The results from drill hole CM23-14 have increased the size of the sedimentary breccia unit and the higher grade mineralised envelope within that unit. It has also increased our confidence in the current geologic model for the Colosseum deposit.

“An intersection of 70.1m @ 6.53g/ t that includes 25.9m @ 15.31g/t Au , is very encouraging and when added to the data from previous drill holes, it reinforces our confidence in the stability of the geologic structure.

“Drill hole CM24-15 is underway and is designed to test south east and down dip extension of the sedimentary breccia. This drill hole is almost complete and sections of the drill core have been sent to the lab for priority processing”.

ASX Release 13 February 2024

Diamond Drilling Details - Mineralisation remains open in all directions.

Drillhole CM23-14 was drilled at a dip of -50[o] towards Azimuth 212[o] to test a revised geological model and expand the high grade sedimentary breccia.

The results of the drill hole confirmed the continuation of the primary lithology, sedimentary breccia, with an elongated orientation to the southeast. The consistency suggests stability in the geologic structure and supports the understanding of the deposits composition.

Within the sedimentary breccia, there is a notable volume of high grade mineralisation that has been intersected in a number of drill holes and is further substantiated by the 25.9 metres of 15.31g/t Au in drill hole CM23-14. This high grade mineralisation is an encouraging sign for the potential economic value of the deposit and additional drill holes are planned to test the lateral and down-dip extents of the high grade zones.

Mineralisation at the Colosseum

Mineralisation at the Colosseum mine is primarily contained in two breccia pipes that are made up of a combination of sediment, felsite and granite units. The high grade mineralisation that has been intersected to date has occurred mainly in the breccia unit that has the most sediments, followed by the unit that contains mostly felsite and some sediments. Dolomite has been present in both the sedimentary and felsite breccia units when high grade has been intersected.

Geochemistry Analysis

The Company has ordered a multi-element geochemical analysis on drill hole CM23-14 in an effort to gain more insight into the chemical markers of the high grade sections of the breccia pipes.

ASX Release 13 February 2024

Current Drilling : CM24-15

As at the date of this release, the Company has completed 254 metres of the planned 310 metre, CM24-15 diamond drill hole. This hole is intended to test below CM23-14 for continuation of the high-grade gold mineralisation while also testing for any southeast extension of the sedimentary breccia body at depth.

Note: In relation to the disclosure of visual mineralisation, the Company cautions that estimates of sulphide abundance (and assumed gold content) from drill core logging should not be considered a proxy for quantitative analysis of a laboratory assay result. Assay results are required to determine the actual widths and grade of the visible mineralisation, the results of which are expected in February or March 2024.

Mineral Dynamics – Ord & Hobbs Research

Ground-breaking research out of Western Australia, spearheaded by Mineral Dynamics, Dr Alison Ord and Dr Bruce Hobbs, can assist mineral exploration by focusing on the thermodynamics of hydrothermal mineral systems , particularly gold deposits.

Their work challenges traditional chemical-centric approaches, emphasising the significance of oscillating heat flow patterns as crucial indicators for predicting gold deposit size.

Using data from established mining operations, they provide tools for explorers to better understand mineral systems by using established cumulative probability distribution functions to indicate the size of the system that created the gold deposit.

Described below are the primary differences between the three main probability distributions that are most common for gold deposit analysis, Weibull, Fréchet and Log Normal:

• Weibull Distribution: Typically associated with smaller mineral deposits with limited potential range of mineralisation.

• Indicates rapid heat loss during mineralisation, characterized by a slow birth, quick growth, and quick death of mineralisation flow rates.

• Fréchet Distribution: Associated with larger mineral deposits with a broader potential range of mineralisation. o Suggests minimal heat loss during mineralisation, showing a stronger beginning and an extended continuation of the flow-mineralising process.

ASX Release 13 February 2024

• Log Normal Distribution: Typically associated with very large mineral deposits with an extensive potential range of mineralisation.

• Implies minimal heat loss and a prolonged mineralisation process, with flow rates beginning slowly and continuing to accelerate.

Dateline provided drill hole data from four holes. Ord & Hobbs had no role in selecting the drill holes. Two of the drill holes (CM23 -06 & CM23-08) were from the South breccia pipe and were completed by Dateline Resources Limited and two were historic drill holes from the north breccia pipe that were drilled by BP in the 1980’s (CP-59 and CP-89). All four drill holes were analysed as fitting a Log Normal distribution.

Alison Ord commented “The data for all four drill holes are consistent with a Log Normal distribution”
