Challenger Exploration ( ASX: CEL) (“CEL” the “Company”) is pleased to announce the results from recent drilling targeting extensions to the high-grade mineralisation at the Company's flagship Hualilan Gold Project, in San Juan Argentina. A total of 48 of the 58 drill holes (83%) reported significant gold mineralisation demonstrating the Company's ongoing success in extending the high-grade gold mineralisation at Hualilan.
Highlights
- Ongoing drilling at the Company's flagship Hualilan Gold Project has materially extended thehigh-grade mineralisation in multiple zones with results including (refer Table 1):
- GNDD-491 intersection of 27.0m at 8.9 g/t AuEq, opens an exciting new high-grade target belowprevious shallow drilling, being the first deeper hole on the western Magnata Fault.
- GNDD-302(ext) extended the Main Manto and Footwall Zones at Sentazon 250 metres down dipwith several follow up holes confirming significant new high-grade extensions at depth.
- Results extends the Sanchez Fault and Norte Manto and confirm a significant halo around thehigh-grade with results including 63.0m at 1.1 g/t AuEq incl 4.0m at 7.2 g/t AuEq (GNDD-443).
- Drilling with the portable rig continues to intersect high-grade mineralisation up-dip in theHualilan Hills
Commenting on the results, CEL Managing Director, Mr Kris Knauer, said
“The results from Hualilan continue to impress with this series of results unlocking several excitingnew high-grade targets. The first deeper hole on the eastern end of the Magnata Fault intersected27 metres at 8.9 g/t, opening up a new high-grade target below previous shallow drilling.
Deeper drilling at Sentazon hasreturned outstanding results extending the high-grade mineralisationmore than 200 metres down dip in multiple locations. Additionally, several deeper holes, for whichassays are pending, are logged as containing zones of massive sulphides within skarn alteration. Thisis typical of other high-grade intercepts at Hualilan and we expect assays to confirm a significantnew zone of high-grade mineralisation down-dip at Sentazon."

Additional High Priority Antimony Targets Identified over 10km Corridor at Yallalong Project
Highlights
- Ground geophysical survey over the identified 10km antimony corridor at Yallalong is complete and final data has been processed and interpreted.
- Detailed interpretation of the geophysical data integrated with previous drilling data significantly expands the scale of the exploration model for high-grade antimony mineralisation at Yallalong.
- 14 new, high priority, structural targets analogous to the high-grade Discovery Target have been identified and will be evaluated in the next drilling campaign.
The geophysics has identified 14 new structural antimony targets at Yallalong analogous to the Discovery Target, where historic drilling intercepted high-grade antimony.
Octava’s Managing Director Bevan Wakelam stated, "The new gravity data redefines the exploration model for high grade antimony at Yallalong. It explains the presence of anomalous antimony along the structural corridor and predicts potential hot spots along it. It is exciting to consider the possibility of a continuous system extending under cover for more than 10 kilometers and having a method to pinpoint the most prospective zones. Planning work is already underway for drilling of these new targets "
Antimony
The Yallalong project is located ~ 220km to the northeast of the port town of Geraldton in Western Australia. The antimony (Sb) mineralisation identified at Yallalong appears within a 10km north- south striking mineralised corridor.
Previous exploration identified four principal antimony targets where antimony mineralisation was exposed at surface. Only the Discovery Prospect had previous drilling and recorded high-grade antimony intercepts over a strike length of ~300m, including 7m @ 3.27% Sb.
A detailed geophysical survey was undertaken to identify underlying structures, such as shears and faults, which act as conduits to mineralising fluids. It also outlines key lithological boundaries. These factors are important in the formation of antimony deposits worldwide.
Interpretation of the geophysical data and the historic drilling has re-defined the exploration model for high grade antimony at Yallalong. Fourteen new targets analogous to the Discovery Target have been identified and will be evaluated through planned drilling. See Figure 1.

Atlas Geophysics conducted the gravity survey using a 100m x 100m grid pattern, with additional measurements on a 50m x 50m grid over the Discovery Target. NewGen Geo, a geophysical consultancy, carried out the gravity data processing and interpretation.

Ore Purchase Agreement with Westgold Resources Unlocks Gold Production from Crown Prince
HIGHLIGHTS
- New Murchison Gold (NMG) and Westgold Resources (Westgold) have entered into an Ore Purchase Agreement (OPA) which will underpin production from NMG’s Crown Prince deposit near Meekatharra, Western Australia in 2025.
- Subject to final regulatory permitting, under the OPA, NMG will commence mining from a new open pit operation at Crown Prince with a targeted commencement date of mid-2025.
- Ore will be hauled 33km by road to the Bluebird Gold Processing Plant, part of Westgold’s Murchison Gold Operations at Meekatharra.
- Ore will be sold to Westgold in several parcels (Ore Parcels) totalling 30-50kt per month with each Ore Parcel certified for grade, moisture and recovery from sampling at the Crown Prince site and a recovery factor agreed for each mining bench from test work replicating the Bluebird Mill circuit.
- The OPA has no fixed term although NMG envisages that most of Crown Prince ore is likely to be processed in an “Initial Period” which runs over the first 24 months of the agreement. Thereafter ore tonnages are to be agreed on a rolling three-month basis once production forecasts have been completed by NMG and Westgold has confirmed mill availability.
- Westgold will purchase ore from NMG based on contained gold in each Ore Parcel at the prevailing AUD gold price in the month the Ore Parcel is collected (minus processing costs and a capital recovery charge). Westgold must promptly collect Ore Parcels that are available for collection.
- The OPA is subject to shareholder approval (Listing Rule 10.1 requirement) at a general meeting of NMG shareholders to be held in late January or early February 2025.
- NMG and Westgold have also entered into an ancillary agreement (Licence and Access Water Discharge Deed) which facilitates NMG’s potential dewatering requirements at Crown Prince.
Alex Passmore, NMG’s CEO commented: "We are very pleased to announce the Ore Purchase Agreement with Westgold as it sees both companies working together to support the development of NMG’s Crown Prince deposit in a capitally efficient manner.
We see this Agreement as beneficial to all shareholders with Westgold acquiring additional high grade oxide ore feed to supplement its Meekatharra operations and NMG transitioning to a producer for modest capital.
The Bluebird Processing Plant owned by Westgold is ideal for NMG due to its close proximity and well-matched metallurgical process. We believe the robust frameworks and protocols we have put in place in this Agreement aligns both operational teams to a common goal of maximizing operational efficiency.
We thank the Westgold team for the technical and commercial work that has led to this Agreement and look forward to working collaboratively in making the development of Crown Prince a success”
Crown Prince is located to the north of Meekatharra, around 33km via road to the Bluebird Gold Processing Plant (Bluebird) owned and operated by BBGO. Westgold and NMG have been working collaboratively on the OPA to manage technical risks and to share economic synergies which are available via the partnering of production from the Crown Prince deposit and milling at Bluebird.
Key Terms of the OPA are outlined in the Table below and will be explained fully in a Notice of Meeting to be sent to NMG shareholders in December. The NMG shareholder meeting is likely to be held in late January or early February 2025. As a result of Westgold’s 18.7% ownership of NMG, it is deemed a related party under the ASX Listing Rules and so the OPA includes a condition precedent of NMG obtaining shareholder approval under Listing Rule 10.1.
BDO Corporate Finance Australia Pty Ltd (BDO) has been engaged to provide an opinion and Independent Expert’s Report to accompany the Notice of Meeting to assist shareholders in their considerations of whether or not to approve the OPA moving into operation.
Should the conditions precedent be met (shareholder approval) the OPA will come into effect with NMG expecting mining approvals to be received in early April 2025. Once mining operations commence, and ore stockpiles are built up, it is anticipated that first Ore Parcel sales will occur in September 2025.
The company is working towards an ore reserve estimate to provide further detail on the economics of the project which is to be released shortly.
