- Pioneer has identified a major cross-cutting structure targeting mineralised zones.
- High-grade tungsten, gold, and gallium confirm a large-scale system.
- Upcoming drilling, EM surveys drive development timelines.
Pioneer Minerals (ASX:PMM) has just identified new structural features and a major northeast-trending fault that cross-cuts the historic Springfield Mine area at its Springfield tungsten, gold, and gallium project in Idaho, after recently completing a high-resolution LiDAR structural interpretation.
Hear from all the ASX-listed companies that were at the RIU Resources Round-Up in Sydney, right here on HotCopper.com. Over a dozen interviews.
This anomaly may represent either a roof pendant structure or massive pyrrhotite mineralisation, the explorer said. Both settings are historically associated with tungsten mineralisation at the Springfield Mine.
Either way, these “previously unrecognised structural features” set up perfect high-priority targets for Pioneer’s next planned exploration – Pioneer management considers these cross-cutting structures highly prospective, and believes they may serve as fluid pathways for the tungsten, gold, and gallium.
The LiDAR work also highlighted extensive faulting at granitic-carbonate contacts, which are favourable environments for skarn-hosted mineralisation.
“The identification of a… NE-trending cross-cutting structure directly through the Springfield Mine area represents an importance [sic] advancement in our understanding of the Springfield system,” Pioneer CEO Michael Beven said.
“The interpretation significantly strengthens our geological model and provides high-priority targeting criteria for the EM survey and maiden drill program.
“Importantly, the LiDAR work continues to demonstrate Springfield is emerging as a large-scale multi-commodity mineralised system with overlapping structural and geological controls associated with mineralisation.”
Springfield has been emerging as a multi-commodity critical minerals project. Recent reconnaissance chip sampling confirmed widespread gallium enrichment, with high-grade results including 128.7ppm and 94.8ppm Ga2O3.
Notably, collected data has suggested that gallium mineralisation occurs independently of tungsten pathways, which may indicate a separate host phase.
The ASX-listed company has physically staked 212 lode claims covering ~18.37 square kilometres in Idaho. While the claims are staked under the established Bureau of Land Management “first-come, first-served” system, Pioneer has noted that final confirmation of the tenure status is still pending.
Heading into Tuesday, PMM shares are 12.5c a pop.
