Great Boulder Resources (ASX:GBR) is designing a follow-up soil sampling program to infill anomalous areas and improve spatial definition at its Wellington Project in Western Australia, upon identifying ‘large-scale’ anomalies.
Managing Director Andrew Paterson says the next steps will be infill sampling within anomalous areas, which will improve their definition prior to starting gravity surveys, after which it hopes to have enough detailed information to start planning a drilling program.
The $37.11 million market capitalisation company also plans to undertake regional mapping to gain an understanding of the stratigraphy within the project area.
Great Boulder says this will be key to understanding the relative positions of target lithologies, possible aquiclude horizons, and feeder structures controlling mineralisation.
During the second half of 2024, airborne gravity surveys are planned, pending contractor availability.
Of particular note, a rock chip sample taken by KingX in 2010 contained fine galena and was assayed at 0.3% Pb, within the north-western anomaly at Wellington.
Meanwhile, the company announced today (15 January), soil sample assays confirm coincident zinc and lead anomalism in the northwestern and eastern areas of the Wellington Project.
Paterson says: “Our first field program at Wellington has confirmed our target model as the first pass soil sample data has identified large, coincident zinc-lead anomalies in 3 areas. The samples were taken on a 1km grid and we have defined anomalies up to 8km wide.”
Great Boulder reports the assays returned broadly match the original Geological Survey of Western Australia (GSWA) sample data which averaged 3 to 4km between samples.
The levels of zinc and lead in soils are thought to be highly anomalous with peak values of 114 parts per million (ppm) and 58.6ppm, respectively.
Great Boulder collected 700 soil samples across the project area during October and November 2023. The samples were assayed by Intertek Genalysis in Perth, Western Australia.
Further, the company notes its short and medium-term focus remains firmly set on growing the Side Well Project’s resource, as well as making new discoveries.
Great Boulder Resources is a mineral explorer focused on its gold and base metal assets in Western Australia.
As of 30 September 2023, the company had $2.5 million cash at hand, according to its latest quarterly report. Post-quarter-end, Great Boulder conducted a placement to raise $4.5 million.
