Summary of Mineral Resource Estimate and Reporting Criteria

Geology and geological interpretation

The Colosseum deposit is located at the southern end of the Sevier foreland thrust belt in the southern Basin and Range Province, SW USA. The project lies within in the Clark Mountain Mining District in the northeast portion of the Clark Mountain Range. The district includes the Mountain Pass rare earth mine seven miles south of the Colosseum Mine, numerous abandoned copper mines, and scattered fluorite, antimony, and tungsten prospects. Most gold and silver deposits in the district are within the northeast quadrant of the district north of Clark Mountain and are associated with emplacement of a felsic breccia complex into Precambrian basement rocks.

The deposit itself is associated with the emplacement of a breccia complex into Precambrian gneissic basement rocks. The complex is comprised of two felsite breccia pipes that form a northeast-southwest elongate zone, which contains mineralised zones of disseminated auriferous pyrite.

Gold at the Colosseum deposit is generally sub-microscopic and associated with sulphide mineralisation, chiefly pyrite. It occurs as free gold, with minor alloyed silver. Gold is primarily in contact with pyrite, in fractures in the pyrite or along pyrite grain edges. It also occurs as isolated particles in quartz and other gangue minerals but spatially always close to pyrite but rarely as particles encased in euhedral pyrite.

The Colosseum deposit style is a hydrothermal breccia pipe with a combination of epithermal mineralisation at original higher levels and mesothermal mineralisation at the lower levels.

Drilling Information

A total of 616 holes for a total of 59,136.58 metres have been drilled in the Colosseum Mine area. The historical drilling was completed from 1972 to 1991 and includes 599 holes for a total of 55,609 metres. Most of the historical drilling was done using reverse-circulation ( RC ) and conventional rotary methods. An inventory of known drilling in the area totals 5,166 metres in 262 Air Trac holes, 6,611 metres in 31 core holes, 40,288 metres in 273 RC holes and 3,543 metres in 33 rotary/percussion holes.

Between April 2022 and April 2024, Dateline drilled 17 diamond core holes (with one abandoned hole) along existing haul roads within the South Pit, for a total of 3,527.65 metres. The majority of this drilling is aimed at confirming mineralisation grades at depth and to better define lateral margins to the deposit.

ASX Release 6 June 2024

All the Colosseum drillhole data is used in developing the Mineral Resource model, with the exception of one historic drillhole, CP-2, which is an exploration hole testing an IP anomaly and is outside the area of the Mineral Resource.

Sampling and sub-sampling techniques

Sampling was predominantly on 5 feet (1.6m) intervals with a sizeable proportion at 2 feet (0.6m) intervals. Core sampling consisted of sawn half core whilst RC and rotary sampling comprising a split of the bulk sample using a free standing riffle splitter. No compositing was undertaken on the RC samples. The sub-samples were then sent to a commercial laboratory for sample preparation and analysis.

Individual laboratory sample preparation procedures for the different historical drilling campaigns varied slightly but followed a standard analytical industry process of taking submitted samples through successive stages of reducing particle sizes and weights to obtain representative subsamples for assaying. Procedures comprised drying, crushing (jaw or rolls), splitting (riffle), pulverizing (spindle, plate, bowl), splitting (scoops) and fire assaying.

Quality Assurance/Quality Control ( QAQC ) programs for the drilling have demonstrated that sample preparation and laboratory performance for the various drilling campaigns provided sample assays which are considered appropriate, with sufficient accuracy and precision, for the purpose of defining a Mineral Resource estimate.

There were no reports of significant numbers of wet samples for the RC drilling. Field duplicates were collected for the RC drilling at a ratio of 1 in 21 samples and indicate good precision and accuracy for the gold results.

The sample preparation, sample size and analytical method are deemed appropriate.

Sample Analysis

Historic sample analysis was by fire assay with a 30 to 60g charge using a lead collector and an AAS finish. Use of Certified Reference Materials (standards) indicate no issues with the accuracy of the reported laboratory results. There were no unusual or questionable gold assaying methods used. Copies of submittal sheets and assay certificates are available for most of the later drilling campaigns. Gold assay values were reported as ounces per short ton and were converted to grammes per tonne for the resource estimation.

The DTR core samples were assayed for gold at ALS Global and Paragon Geochemical in Reno, NV, using a fire assay method with a 30g charge. The QAQC procedure included standards, blanks, and duplicates which indicate no issues with the assay results.

The fire assay analytical methods used for Colosseum are considered as total digest techniques and appropriate for the commodity type and style of mineralisation.

Estimation Methodology

Recoverable Multiple Indicator Kriging ( MIK ) was used to complete the gold grade estimation using HSC’s inhouse GS3M modelling software. The geological interpretation, such as it is, block model creation and validation were completed using the Surpac mining software. HSC considers MIK to be an appropriate estimation technique for the type of mineralisation and extent of data available.

The drillhole database was composited, with no constraints, to 1m intervals covering the whole of the prospect. The 1m composite interval may lead to a smoothing out of the variance but is unlikely to have a significant impact on the global estimates. A minor amount of peripheral, isolated data was removed from the composite

ASX Release 6 June 2024

file. A total of 54,313 composites were generated from the drillhole database, using the Surpac ‘best fit’ option and modelled for gold only. Two drilling domains were employed, one for the South Pit (domain 1) and another for the North Pit (domain 2), reflecting a difference in intensity of drilling and assay grades.

Metal variogram maps of gold for domains 1 and 2 indicated weak results, which points to a lack of structure to the gold data. Overall grade continuity was very modest with a weak E-W trend for domain 1 coupled with a steeply west plunging feature in the XZ plane and a vertical plunge in the YZ plane. For domain 2, a WNW trend was interpreted with a subvertical plunge in both the XZ and ZY planes.

Grade interpolation was unconstrained, except by the search parameters and the variography, in acknowledgement of the gradational nature to the margins of the gold mineralisation and the abundance of buffering low grade peripheral values.

No base of oxidation was used. No cover surface was created as the mineralisation is outcropping and is exposed in many places along its ridge line and flanks and where previous open pit mining had occurred.

A fundamental concept behind MIK method is that it generally precludes the need for top cutting. However, in this case, two extreme consecutive samples from one drillhole were top cut to 500g/t.

Block dimensions are 10m by 10m by 5m (E, N, RL respectively) with no sub-blocking. The selective mining unit ( SMU ) is 5m by 5m by 2.5m. The north and east dimensions were chosen as they are a close to the nominal drillhole distances in the detailed drilled area of the South Pit. The vertical dimension was chosen as a compromise between the two deposits, a reflection of the sample spacing, possible mining bench heights and to allow for flexibility in potential mining scenarios after discussions with independent mining consultants AMDAD.

Both domains were modelled as a combined dataset with soft boundaries and separate conditional statistics. A total of 5 search passes were employed with progressively larger radii and/or decreasing data point criteria. The initial search parameters for domain 1 were 20m by 20m by 35m with a minimum of 16 data and 4 octants increasing to a final Pass 5 search of 60m by 60m by 120m with a minimum of 8 data and 2 octants. For domain 2, the initial search was 25m by 25m by 25m with the same data requirements expanding to a Pass 5 search of 70m by 70m by 70m with a minimum of 8 data and 2 octants. The slightly different search dimensions are a function of the mineralisation in each pit.

The maximum extrapolation for the Mineral Resources is the Pass 5 search.

No other elements were modelled, therefore there are no assumptions about correlation between variables. No by-products are anticipated from production. No assessment has been made for any deleterious elements.

Drillhole spacing ranges from 10 to 15m in the core of the two domains but at a variety of directions giving rise to relatively close spaced samples. Downhole sampling was generally at 5 feet (and 2 feet) intervals.

The mineral resource estimates are controlled by the data point distribution, the variography, block size and the search ellipse. Conventional use of wireframes to control the mineralisation was not considered necessary in this case.

The new block model was reviewed visually by HSC and it was concluded that the block model fairly represents the grades observed in the drillholes. HSC also validated the block model using a variety of summary statistics and statistical plots. No issues were noted. Validation confirmed the modelling strategy as acceptable with no

ASX Release 6 June 2024

significant issues.

Comparison with the 2022 mineral resource estimates indicated a larger tonnage for the 2024 Mineral Resource by 27% and at a very slightly higher gold grade. None of this is unexpected based on the different modelling strategy and the additional drilling data.

Tonnages are estimated on a dry weight basis and moisture content has not been determined.

The historic mining operation exploited both the South and North Pits but there are no meaningful production figures available to allow for any reconciliation with the new Mineral Resources.

Density

No historical density data was supplied.

53 density measurements were supplied by the Company from their recent drilling. Samples consisted of single pieces of core 10-15cm long and density was measured using an immersion in water technique i.e. the Archimedes Principle of weight in air / (weight in air minus weight in water). The average density value was 2.66t/m[3] with a range of 1.96 to 3.37t/m[3] . Density values tended to show an increase with hole depth.

A default density of 2.65t/m[3] was used for the Mineral Resources and is considered reasonable.

Cut-off grades

The recoverable MIK resources are reported at a gold cut-off of 0.5g/t based on the outcome of a recently completed pit optimisation study by independent mining consultants AMDAD of Brisbane. The cut-off grade at which the mineral resource is quoted reflects the intended bulk-mining approach. Consideration of “reasonable prospects of eventual economic extraction” has utilised an optimised pit shell with a revenue factor of 1.3 at a US$2,400/oz gold price with preliminary estimates of mining costs and pit wall slopes.

Classification criteria

The classification of the recoverable Mineral Resources is based on the data point distribution which is a function of the drillhole spacing and the search parameters. Search Pass 1 equals Measured Resource, Search Passes 2 & 3 equal Indicated Resources and Search Passes 4 & 5 equals Inferred Resource.

Other aspects have been considered in the classification including the host geology and style of mineralisation, validation of the historic drilling, sampling methods and recoveries, the QAQC programmes and results and comparison with previous resource estimates.

HSC believes the confidence in tonnage and grade estimates, the continuity of geology and grade, and the distribution of the data reflect Measured, Indicated and Inferred categorisation. The estimates appropriately reflect the Competent Person’s view of the deposit.

Mineral Resource

The new recoverable Mineral Resources for the Colosseum gold deposit are reported for a gold cut-off grade of 0.5g/t constrained to the block centroid being above the optimised pit shell and below the current topographic surface.

Mining Studies

The updated MRE will be used as the basis for the Company to determine the best mining and development option for the Colosseum project. Australian Mine Design and Development Pty Ltd ( AMDAD ), have been retained to advise and manage the study.

Three options will be considered being

Open pit both breccia pipes
Sub level cave the South breccia pipe and open pit the North breccia pipe
Bulk mine both breccia pipes by expaning the two pits into a single large pit

AMDAD have extensive experience in advancing projects similar to the Colosseum through mine development and production.

Drilling program

The Company is currently reviewing options for its drilling program. The objective of the review is to ascertain the most cost effective way to determine the depth extent of the gold mineralisation and expand the Mineral Resource beyond the 1.1 million ounces of gold disclosed in this release.

Additional Information

The Company continues to pursue non-dilutive funding to undertake exploration for Rare Earth Elements (REE) at the Colosseum. If the Company is succesful at securing non-dilutive funding then the overall work program at the Colosseum mine will be expanded accordingly

Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	The preponderance of samples for all drill programs of all operators were taken at 5-foot intervals, which is customary for RC drilling, and is significantly less than the thickness of the bulk-tonnage style of mineralisation at the Colosseum mine. Each drill sample interval is therefore a fraction of the true thickness of the mineralized zones. The predominant sample length for the drill intervals in the Colosseum database is five feet (28,339 samples out of 35,836– 79%)

2022 Drilling

Dateline Resources Limited completed 605 metres (1,986 feet) of drilling in 5 drill holes at the Colosseum Project. All the drilling was done from the surface with HQ diamond drill core. Industry standard core handling and sampling procedures were employed to ensure high quality samples.

Core samples were collected at 5 foot intervals.

All core was logged for rock type, RQD, and recovery and dispatched for assay with standard 5 foot long sample intervals.

Logging geologist identified zones of interest, but the entire hole was measured and marked up in 5 foot intervals. Whole core was sampled.

Core was bagged into pre-numbered bags, and taken to the FEDEX Freight office in Las Vegas, palletised by the Logging Geologist, covered in shrink wrap and handed over to the FEDEX dock personnel for overnight shipping to Paragon Geochemical Laboratory in Sparks Nevada.

Samples were sent to Paragon Geochemical in Sparks, Nevada for sample preparation and assaying. Samples were dried, weighed, crushed and split to obtain 1 kg. The split samples were placed in a ring and puck mill to produce 85% minus 75 micron pulp. This material was blended on clean cloth and packaged in paper pulp bags. Using a pulp balance, a 30gm sample was weighted out for standard lead collector fire assay with an AAS finish. Overlimit values using a 5 ppm threshold were analysed via gravimetric analysis.

All samples followed a strict Chain of Custody.

Routine QAQC samples were inserted in the sample runs at a rate of 20%, comprising Certified Reference Materials from CDN Resource Laboratories Ltd., and verified blank granitic material.

Commentary

Block dimensions are 10m by 10m by 5m (E, N, RL respectively) with no sub-blocking. The selective mining unit (SMU) is 5m by 5m by 2.5m. The north and east dimensions were chosen as they are a half to a third of the nominal drillhole distances in the detailed drilled area of the South Pit. The vertical dimension was chosen to reflect the sample spacing and possible mining bench heights and to allow for flexibility in potential mining scenarios.

Both domains were modelled as a combined dataset with soft boundaries. 5 search passes were employed with progressively larger radii and/or decreasing data point criteria. Details of search passes are:

The maximum extrapolation for the Mineral Resources is shown as the Pass 5 search.

No other elements were modelled therefore there are no assumptions about correlation between variables.

The resource estimates are controlled by the data point distribution, the variography, block size and the search ellipse. Conventional use of wireframes to control the mineralisation was not considered necessary.

The new block model was reviewed visually by HSC, and it was concluded that the block model fairly represents the grades observed in the drill holes. HSC also validated the block model using a variety
