Phase 1 ¹ First-In-Human study designed to assess safety   ,   tolerability   , right dose for Phase 2 and early signs of efficacy   of 177Lu-RAD20   2   in individuals with   advanced HER2-positive solid   tumors

Previous clinical proof-of concept data ² for targeting HER-2 demonstrated the safety and biodistribution of 99mTc-RAD202 in humans

Radiopharm Theranostics (ASX:RAD, ‘Radiopharm’ or the ‘Company’), a clinical-stage biopharmaceutical company focused on developing innovative oncology radiopharmaceuticals for areas of high unmet medical need, today announced the dosing of the first patient in its Phase 1 ‘HEAT’ clinical trial of RAD202, a proprietary nanobody that targets Human Epidermal Growth Factor Receptor 2 (HER2)-positive expression in a wide array of advanced solid tumors.

The open-label Phase 1 ‘HEAT’ clinical trial is a dose escalation trial of 177Lu-RAD202 that is designed to determine the recommended Phase 2 dose and to evaluate the safety and preliminary clinical activity of this novel radiotherapeutic in individuals with HER2-expressing advanced cancers. The study is currently being conducted at clinical centers across Australia.

‘Dosing patients in the HEAT clinical trial marks an important milestone in our transition to a clinical-stage company,’ said Riccardo Canevari, CEO and Managing Director of Radiopharm Theranostics. ‘Despite progressive improvements in the management of metastatic HER2-positive disease, the majority of patients experience disease progression on current standard of care and require further therapeutic options. The dosing of the first patient in the ‘HEAT’ trial represents a significant step toward achieving RAD202’s potential to address an unmet need for HER2-positive metastatic patients who are progressing or unable to tolerate current treatment options. With RAD202, we hope to provide an option that can meaningfully improve clinical outcomes for HER2-positive patients, while preserving their quality of life.’

HER2 is overexpressed in breast cancer as well as several other solid tumors and represents a validated target in oncology. RAD202 is a proprietary single domain antibody that targets HER2. Ten HER2-positive breast cancer patients previously dosed in a Phase 1 diagnostic study of RAD202 demonstrated clinical proof-of concept as well as the safety and biodistribution of RAD202, validating its potential for the treatment of advanced HER2-expressing cancers ² . Preclinical findings ³ examining the therapeutic effect in HER2-positive xenografts were also recently reported with 177Lu-RAD202. Collectively, these data further justify first in humans dose finding studies.

‘It is a privilege to be the first centre to administer 177Lu-RAD202, targeting HER2-positive tumors in this Phase 1 clinical trial (HEAT).’ said Dr Aviral Singh, Clinical Head of Theranostics and Nuclear Medicine at St John of God Murdoch Hospital. ‘This opens the possibility of novel therapeutic avenues for patients with aggressive tumor types, including breast, ovarian, gastric, pancreatic, bladder, and several other cancers. With the trust put in us by Radiopharm, we look forward to a successful trial with beneficial outcomes for our patients.’

LaFleur Minerals Inc. (CSE: LFLR) (OTCQB: LFLRF) (FSE: 3WK0) (‘LaFleur Minerals’ or the ‘Company’) is pleased to provide the results of its recent exploration programs, including an update on its diamond drilling and bulk sampling plans at its district-scale Swanson Gold Project (‘Swanson’), positioned in the prolific Abitibi Gold Belt (Figure 1). The Company is also fast-tracking the restart of its 100%-owned, 750 tonne per day (‘tpd’) Beacon Gold Mill (‘Beacon’) in Val-d’Or, Québec, and has received significant interest from several groups for the purpose of financing the mill restart as well as to offtake material and support the ramp-up to full production with the goal to be generating cash flow by early 2026.

The interest received to date is a strong vote of confidence in the quality and potential of the Beacon Mill, as a foundational and keystone asset of the Company, its strategic positioning in one of the world’s richest and most well-endowed mineralized mining regions with numerous surrounding gold deposits suitable for bulk sampling, which would be ideal sources of mineralized material to complement this transformational next phase of development for LaFleur Minerals.

HIGHLIGHTS

• Immediate plans to complete at least 5,000 metres of diamond drilling at Swanson starting in June using existing flow-through (FT) funds, with over 50 promising drilling targets identified, among the other highly prospective Bartec, Jolin, and Marimac gold targets. A drilling contractor has been selected with drilling permits expected by early June.
• Geological and engineering planning continues for a large bulk sampling program at the Swanson mining lease with an updated Scoping Study and mine plan to be submitted to Québec government for approval. The plan includes the extraction of an up to 100,000 tonne surface bulk sample at Swanson for processing at the Beacon Mill once it is in full production (anticipated by early 2026).
• The Company is in advanced discussions with several institutional and private equity groups, as well as exploring non-dilutive funding options with several commodity trading and debt financing firms to fund Beacon Mill’s restart. The Company’s goal is to be fully-funded, complete upgrades, and become fully operational by early 2026.

Paul Ténière, CEO of LaFleur Minerals, commented, ‘We are very excited to commence our summer diamond drilling program to test the regional exploration targets identified from our recent exploration programs at Swanson. These drilling targets are based on careful and well executed geological, geochemical, and geophysical programs by our technical team. Swanson is a large regional exploration project with numerous gold showings and the upcoming diamond drilling program will focus on showings that have the potential to host significant large gold deposits.

‘In addition, we are forging ahead with the permitting process for the Swanson bulk sample and funding the restart of the Beacon Gold Mill to generate cash flow as quickly as possible, with the longer-term vision of funding additional project acquisitions and expanding LaFleur Minerals from a small to intermediate gold producer in the Val-d’Or region. With a restart cost that is so low, LaFleur Minerals has the ability to move towards commercial production and profitability near term, achieving an outstanding milestone in an exceptionally short period of time thanks to the methodical work of the Company’s technical and management team, largely supported by the increasingly attractive precious metals market.’

SUMMARY OF RECENT SWANSON EXPLORATION RESULTS

LaFleur Minerals recently received the final reports for its 2024 prospecting and reconnaissance mapping, soil sampling program, and IP survey. This exploration data has been incorporated into the Company’s geological and GIS database, along with the regional high-resolution magnetic and VLF-EM survey completed earlier in 2024, which has been used to develop priority drill targets to be tested this summer.

Geological Reconnaissance Mapping and Prospecting

Geological reconnaissance mapping and prospecting was carried out in September 2024 by IOS Géosciences Inc. (‘IOS‘). The work, including the collection of 144 samples that were sent to the laboratory, focused on key deposits, showings, and mineralized outcrops, compiled from the literature (Figure 2). Out of the 25 mineral occurrences reported since 1926 at Swanson, 10 were selected to represent the focus of interest. The Swanson, Jolin, Barautte VII, and Jackson showings display characteristics that are indicative of orogenic-gold-type mineralization and magmatic-hydrothermal-type mineralization. The reported results included the discovery of new highly prospective lithologies, hydrothermal alterations, sulphide mineralization, and corresponding gold grades. Best gold grades from grab samples included:

• 11.71 g/t Au located 425 m SW of the Jolin deposit
• 4.59 g/t Au located 140 m south of the Barautte VII showing
• 4.51 g/t Au and 3.78 g/t Au in the area of the Jackson showing
• 2.98 g/t Au in the area of the Bartec showing

Please note: Grab samples are selective by nature and may not be representative of the overall mineralization on the Swanson Project. While they are useful for identifying areas of interest and guiding further exploration, they should not be relied upon as an indicator of the average grade or extent of mineralization.

Soil Survey

A soil survey was also carried out in September 2024 by IOS. The objective of the 2024 soil sampling program was to assess Swanson’s potential to contain unknown blind gold occurrences by using the dispersion of geochemical signals in surficial materials. The survey included 315 sampling sites distributed along 8 grids according to the local quaternary geology, aerial photos and LiDAR images (Figure 3). The survey was designed to test the efficiency of the method and targeted areas with known occurrences. Lines were oriented perpendicular to the geophysical anomaly and/or geological features.

The gold-enriched soil samples located to the SW of the Damascus showing were found to be associated with an untested IP anomaly. The soil samples near the Jackson showing and Bartec deposit, and samples approximately 750 m SSW of the Swanson deposit and on two lines located 300 to 550 m south of the Jolin deposit, all show gold-enrichment.

Please note: Soil sampling surveys are not definitive, and the results are still at an early stage of interpretation, with no guarantee of a mineral discovery.

Induced Polarization Geophysics Survey

An Induced Polarization (IP) survey was carried out at Swanson between January and April 2024 by TMC Geophysics. The survey consisted of 120.4 line-km of IP using the pole-dipole electrode array with a configuration of a=25 m, n=1 to 16 over two distinct grids, namely Jolin and Bartec (Figure 4).

A total of 64 IP axes indicative of the most obvious anomalies have been identified on both prospects. These include:

• A first group of IP axes characterize some of the strongest and more continuous polarizable anomalies. The associated polarizable sources are typically correlated with slight to strong decreases in resistivity or included within the confines of thin conductive beds/horizons. According to the regional geology, this type of signature is, at least partially, of the lithological type and indicative of the known pyrite and graphite rich units/lithologies of both prospects. On the other hand, one cannot exclude to see these units themselves locally enriched in poly-metallic mineralization (+/- Au). Some other axes of this group may also directly emphasize polymetallic mineralization developed along broad shear zones, or altered geological contacts favored by the upwelling of hydrothermal fluids.
• The second group of IP axes feature weaker and less continuous polarizable anomalies that are partially correlated with an increase in resistivity. They all have the potential to indicate the presence of gold-rich mineralization associated with disseminated sulphide remobilized along a fault or altered and silicified band of rocks (+/- quartz/carbonate veining).

As for the follow-up work, 7 IP axes have been selected to be drill tested on the Jolin grid, and 4 others on the Bartec grid.

2025 SWANSON DIAMOND DRILLING PROGRAM PLANS

Following the regional compilation and high-resolution magnetics and VLF-EM over the entire Swanson Gold Project, along with the recent encouraging results of the reconnaissance mapping and prospecting, soil sampling and IP survey discussed above, LaFleur Minerals will move forward with its regional drilling program.

Approximately 50 drill targets have currently been identified based on the compilation and recent field work. The targets are located regionally in the Swanson, Jolin, Bartec and Marimac regions (Figure 5). Phase I of the diamond drill program will include 20 exploration drill holes totalling at least 5,000 m of diamond drilling.

LaFleur Minerals is pleased to announce that it has signed a drilling contract with Forage Rouillier Drilling of Amos, Québec and is expecting to start drilling at Swanson in early- to mid-June 2025 once drilling permits have been received from the Québec government.

SAMPLE PREPARATION, LABORATORY ANALYSIS, AND QA/QC SUMMARY

Rock (Grab) Samples

All rock (grab) samples collected by IOS during the program were securely transported to Activation Laboratories (Actlabs) in Ancaster, Ontario, an ISO/IEC 17025-accredited laboratory. Grab sample sizes vary by rock collected but varies from 1 kg to 3 kg. Actlabs is independent of LaFleur Minerals. Sample preparation included crushing, splitting, and pulverizing to 95% passing 105 microns. Gold analysis was performed using fire assay with an inductively coupled plasma mass spectrometry (1A2-ICPMS) finish. A multi-element analysis (63 elements) was also done on the samples using an Aqua regia digestion / ICP-MS (Ultratrace-1). Borate fusion with XRF finishing was carried out for samples exceeding the limit for tungsten. The Company follows industry-standard QA/QC protocols, including the insertion of certified reference materials, blanks, and duplicates to ensure the accuracy and precision of the results.

Soil Samples

Soil samples were collected by IOS at a depth of 10 cm to 25 cm below the base of the Ah horizon with an average sample size approximately 1 kg. As such, the sample can be composed of either the Ae, B or C horizon, or be a composite of these horizons depending on the soil profile. Sampling was done using a shovel or an auger depending on the environment and depth necessary to sample the correct horizon.

Samples were securely transported back to IOS facilities in Saguenay, Québec by the field crew. The samples were prepared in the IOS laboratory for environmental parameter measurements (e.g. pH, Eh, etc.) and handheld XRF analysis. Upon reception of the samples by the IOS lab and prior to any preparation, a 20 gram aliquot was taken to perform measurements that need to be conducted on the raw material. The remaining material was dedicated to preparation for loss on ignition (LOI) and chemical analyses. Environmental parameters such as pH, δpH, Eh and TDS (Total Dissolved Solids, i.e., conductivity) were measured on saturated paste according to standard procedures.

Samples were then securely courier shipped to ALS Minerals in Val-d’Or for final preparation before the final shipping to ALS Minerals in Vancouver for Ionic LeachTM. ALS Minerals is independent of LaFleur Minerals. Sample material dedicated for chemical analysis were air dried and sieved at

The anomaly thresholds were determined by IOS using a probabilistic approach. In that the assays results are first transformed into logarithmic data. The Z-score is then calculated for each element of each sample. This significantly limits the range of values and enables the use of a normal distribution for the probability modelling. The anomaly threshold for an element is determined by the difference between the sample’s Z-score and the expected Z-score for a log-normal population with an average of 0 and a standard deviation of 1, which represents the regional background as confirmed by the analysis of IOS’s large database. Any sample deviated from that regional trend is likely related to an anomalous population.

Location and Geological Overview:

Coyote Knoll is located in central Utah, approximately 85 km south of Bingham Canyon Cu-Mo-Au Porphyry deposit and 40 km southwest of the city of Eureka. Eureka is historically associated with the Tintic Mining District, which has been a major producer of gold, silver, lead, and zinc from both epithermal and Carbonate Replacement Deposits (CRD). The Tintic District is known for its productive mining history and the potential for undiscovered porphyry systems.

Coyote Knoll was discovered in 1988, with subsequent exploration activities including mapping, trenching, rock sampling, and induced polarization and magnetic geophysical surveys. Follow-up work also included near-surface Reverse Circulation RC-drilling, totaling 2,606.96 metres across 33 drill holes. Highlights from historical drilling are summarized in Table 1 & 2, and surface samples are highlighted in Table 3. A 12-ton representative bulk sample was also mined from a shallow open pit, centered over the east-west (70°) trending mineralized structure. Silver and gold epithermal mineralization was exposed over approximately 60 metres within the open pit and has been delineated for 1.5 km through surface trenching, sampling, and shallow RC drilling (Figure 2).

Two additional historical drill holes (CK-14^1. and CK-23^2.) have previously been reported to contain high gold values and are in proximity to the open pit. CK-14 has an intercept of 8.19g/t Au and 1,060g/t Ag over 1.52 m from 9.14 m downhole. CK-23 has an intercept of 2g/t Au and 814g/t Ag over 1.52 m from 45.72 m downhole.

While Coyote Knoll is approximately 40 km southwest of the Tintic District the geological setting at Coyote Knoll exhibits similarities to the Tintic Mining District. Where precious metal epithermal veins at the Trixie Mine are formed within faulted quartzites and the Burgin and Tintic Standard mines are hosted in carbonate-rich stratigraphy forming CRD. During the March site visit, the Company also toured the high-grade Trixie Gold Mine to gain further insight into the regional geological setting of the Tintic Mining District. At Coyote Knoll, epithermal mineralization is located along the margin a large volcanic caldera hosting a granitic center. Veining crosscuts quartzite, carbonate-rich stratigraphy and volcanic flows. This provides an encouraging framework for the exploration of both epithermal veins and potential carbonate replacement mineralization at Coyote Knoll.

Fieldwork conducted during a March 2025 site visit confirmed the presence of epithermal-style mineralization with key geological features including:

• Silica-flooded pebble clastic fault breccia (pebble dyke), jasperoid, and chalcedony vein infill hosted within faulted quartzite.
• Mineralization consisted of native silver and silver sulphide ‘sulfosalt’ minerals.
• Secondary northwest-trending epithermal veining represented by quartz-carbonate and jasperoid infill. This trend contains anomalous silver and elevated pathfinder elements such as arsenic (As), copper (Cu), lead (Pb), antimony (Sb), and zinc (Zn) (Table 4).

The Company has not done sufficient work to classify the historical drilling information as current to NI 43-101 and is not treating the historical drilling disclosure as a current mineral estimate. Historical drilling database has not been verified for accuracy or quality. The reported historical values in this release require verification through additional exploration drilling, twinned holes will be used to verify style, grade and widths of mineralization.
2. Grab samples are from select surface material and may not represent true underlying mineralization and drilling is required to confirm mineralization width and grade continuity below surface. Additional sampling is required to verify historical rock sample database.
3. The 12-ton bulk sample reported in 2012 has not been verified for accuracy or quality control and therefore the reported tonnage and grades are not considered a 43-101 mineral resource estimate or a pre-feasibility study. Additional exploration drilling and metallurgical studies are required to verify tonnage and concentrations of silver and gold contained beneath the mined-out area. The bulk sample values are provided to illustrate the presence of surface mineralization.
4. The 1,000 ounces of silver doré, produced in 1998 reported by Phoenix Gold Resources has not been verified. This information is not considered a mineral resource estimate as there were no reported head grades or tonnage provided. Additional drilling and metallurgical studies are required to verify width, strike and plunge of the surface mineralization reported from the open pit operation at Coyote Knoll. This bulk sample information is provided to illustrate the presence of surface mineralization.

Rock samples collected during the site were located using a handheld GPS, material was sealed in heavy poly ore sample bags with a representative sample retained for future inspection. Samples were placed into a 5-gal pail and shipped to ALS Vancouver for analyses. Samples were crushed, split and pulverized using PREP-31 specifications and analyses was completed using ME-GRA22 for Ag and Au as well as ME-MS41 for a multielement output utilizing an aqua regia digest, over limit elements (Ag, Cu and Pb) were analyzed using OG46.
