OD6 Metals has extended the high-grade fluorspar footprint at its Quinn project in Nevada, with rock-chip assays reaching 95.6% CaF₂ along a 350-metre trend from Blue Bell to Shannon Queen. The result elevates the corridor to a priority exploration target, although drilling is still needed to establish continuity, depth and scale.
- 350-metre Blue Bell to Shannon Queen fluorspar corridor identified
- Nine of 22 rock chips exceeded 59% CaF₂
- Four samples returned more than 90% CaF₂, peaking at 95.6%
- Individual veins ranged from 10 centimetres to several metres
- Follow-up mapping and structural work planned ahead of future drilling
High-grade fluorspar extends beyond Blue Bell
OD6 Metals Limited (ASX:OD6) has found high-grade fluorspar across a 350-metre corridor linking its Blue Bell prospect with the historic Shannon Queen workings in Nevada. Nine of 22 reconnaissance rock-chip samples returned more than 59% CaF₂, including four assays above 90% and a peak result of 95.6% CaF₂.
The results extend the story beyond the compact historic Blue Bell workings. The company’s earlier Blue Bell channel results included a 24-metre channel sample grading 51.1% CaF₂, while rock chips reached 98.4%. The latest traverse suggests high grades are not confined to the quarry area, although the new results come from selective surface sampling rather than drilling.
Vein widths point to a wider target zone
OD6 reported fluorspar-bearing veins ranging from 10 centimetres to several metres wide along the traverse. One sampled vein was recorded at 1.7 metres, while another was described as 30 centimetres wide; the company also identified flanking stockwork and breccia that together form a zone of appreciable width.
That geological picture is encouraging but incomplete. Rock chips can demonstrate the presence and tenor of mineralisation at surface, not its true width, depth continuity or economic scale. OD6’s own JORC disclosure says the sampling does not provide enough information for a mineral resource estimate, and no drilling was reported in the announcement. The corridor remains open to the west through altered volcanic rocks.
Quinn strategy now includes another priority corridor
Blue Bell-Shannon Queen is now being treated as a priority exploration area alongside Horseshoe, Mammoth and Big Jim, approximately 12 kilometres south of Horseshoe. OD6 said the steeply dipping geometry may allow drill sites to be positioned from the valley below, subject to the required permitting.
The discovery also feeds into the company’s preliminary hub-and-spoke concept for Quinn, under which multiple satellite mineralised areas could potentially supply a central processing facility. That remains a development hypothesis rather than an established plan: further exploration, resource definition, metallurgical testing and economic evaluation are required before any configuration can be determined.
Follow-up work will test whether the corridor holds together
OD6 plans further mapping, sampling and structural interpretation across the 350-metre trend, while continuing metallurgical and ore-sorting programs aimed at assessing potential Metspar and Acidspar pathways. The company is also progressing US Forest Service permitting and preparations for proposed early-2027 drilling and bulk sampling at Horseshoe to Mammoth, with future environmental and cultural studies required for subsequent drilling applications at Blue Bell.
Bottom Line?
The headline grades are strong, but the next value-defining step is converting selective surface evidence into drill-tested continuity and a resource framework.
Questions in the middle?
- Will follow-up work confirm that the high-grade surface veins connect continuously between Blue Bell and Shannon Queen?
- When will permitting allow OD6 to test the corridor at depth with drilling?
- Can metallurgical and ore-sorting work support a viable central processing model across Quinn’s separate occurrences?
