Amoco Drilling Yields Broad Gold-Antimony Mineralisation with Up to 0.38 g/t Au Intercepts
Critical Resources Limited’s maiden drilling at the Amoco Gold-Antimony Project confirms a substantial orogenic mineralised system, underpinning its exploration model and setting the stage for further work in NSW’s New England Fold Belt.
- Maiden RC drilling confirms broad orogenic gold-antimony mineralisation
- Hillgrove-style mineralisation features identified in petrographic studies
- Significant multi-element anomalism including gold, silver, antimony, lead
- Strategic location near Larvotto’s Hillgrove and Koonenberry’s Enmore projects
- Follow-up drilling and detailed petrographic analysis planned pending approvals
Exploration Breakthrough at Amoco
Critical Resources Limited (ASX, CRR) has announced a pivotal milestone for its Amoco Gold-Antimony Project in New South Wales, following the completion of its maiden Reverse Circulation (RC) drilling program. The results validate the company’s geological model by confirming the presence of a substantial orogenic gold-antimony system characterised by broad hydrothermal alteration and mineralisation features analogous to the renowned Hillgrove deposit.
Located approximately 19 kilometres southeast of Larvotto Resources’ Hillgrove Antimony-Gold Project and 14 kilometres east of Koonenberry Gold’s Enmore Gold Project, Amoco sits within the highly prospective New England Fold Belt. This region is historically significant for its gold and antimony production and continues to attract exploration interest due to its fertile geology.
Drilling Highlights and Geological Insights
The maiden RC drilling intersected a structurally controlled, hydrothermally emplaced quartz-sulphide system up to 22 metres wide downhole, with assays revealing multi-element anomalism. Notable intercepts include 1 metre at 0.38 g/t gold and 22.7 g/t silver, and 3 metres at 0.22 g/t gold, 6.4 g/t silver, 0.32% lead, and 103 ppm antimony. These results, while modest in grade, are significant for the broad zones of alteration and pathfinder elements that are typical of orogenic systems capable of hosting higher-grade mineralisation.
Petrological studies of surface rock samples have identified features consistent with Hillgrove-style mineralisation, a key benchmark for antimony-gold systems in the region. Ongoing detailed petrographic analysis of drill samples aims to vector towards higher-grade zones, refining the understanding of mineralisation controls.
Strategic Positioning and Next Steps
Amoco’s strategic location within a well-endowed structural corridor enhances its prospectivity. Critical Resources is progressing permitting with the NSW Resource Regulator for an extended drilling program targeting a ~2 kilometre gold-in-soil anomaly. Future exploration will integrate structural mapping, geochemical analysis, and further petrographic studies to prioritise feeder zones and potential high-grade targets.
Managing Director Tim Wither emphasised the significance of these findings, stating that the confirmation of a substantial orogenic system provides a robust foundation for advancing the project and unlocking value for shareholders. The company’s systematic approach at Amoco complements its broader portfolio, including the Halls Peak Base Metals Project and the Mavis Lake Lithium Project in Canada.
Balancing Optimism with Caution
While the drilling results affirm the exploration model, the grades reported are relatively low and true widths of mineralisation remain to be confirmed. The next phase of drilling and technical studies will be critical to delineate the extent and economic potential of the mineralised system. Investors and analysts will be watching closely as Critical Resources advances its permitting and exploration activities in this promising corridor.
Bottom Line?
Critical Resources’ maiden drilling at Amoco lays a solid groundwork, but the journey to defining an economic deposit is just beginning.
Questions in the middle?
- Will follow-up drilling confirm higher-grade zones within the orogenic system?
- How will permitting timelines impact the pace of exploration at Amoco?
- What insights will ongoing petrographic studies provide about mineralisation controls?
