Cu Target Identified over 2km - Blue Rocks Project

Copper Target Identified over 2km at Blue Rocks Copper Project, Australia
APEX Geoscience completed maiden geochemical sampling programme
Oracle Power PLC (AIM:ORCP), an international project developer, is pleased to announce that results from the maiden geochemical sampling programme have highlighted a number of strong anomalies across the project strike at the Blue Rock Valley Copper and Silver Project (the "Project"), located in the Ashburton Basin in the northwest region of Western Australia.
Highlights:
o Geochemical copper anomalies relate well to known mineralisation, with new zones identified to the northwest and southeast of the main workings area.
o Priority target zone over the area of the main workings extends for approximately 320m.
o Drill traverses have been designed to test anomalies with regulatory and heritage approvals to be applied for.
o Further refinement of targets by geochemical sampling and expansion of area and geophysics being considered.
Apex Geoscience has completed the maiden geochemical sampling programme over the multiple gravity targets identified along the main Blue Rock valley copper mineralised trend of ~2km strike, that has highlighted anomalies, refer Figures 2, 3 and 4, with gravity, magnetics and air photo as basemap.
The geochemical anomalies relate well to known mineralisation, with new zones identified to the northwest and southeast, but do not relate well to geophysical methods used to date. Gravity data appears to relate to general geology, and magnetics does not show any correlation. The next steps to define mineralisation need to be considered, with expansion of geochemical sampling to the North East, over the major crustal suture and towards higher magnetics, and/or further geophysical techniques such as Expert Geophysics MobileMT drone based system. Drilling to test the anomalies can also be considered, with drill traverses proposed.
Conclusions:
o The geochemical sampling programme has defined the mineralised system at Blue Rock trending NW-SE over the survey length of ~2km.
o The responses to the NW appear stronger and are occurring through colluvial cover, whilst to the SE responses are weaker in near outcrop conditions.
o The priority target zone extents for approximately 320m centred on the existing workings.
o The secondary priority zone then extends to the NW for ~400m to the edge of the sampling grid.
o The reconnaissance sampling lines indicate the mineralised trend is open to the NW under cover.
o Further sampling will be required to determine the strike extent and potential of the system.
o The VTEM targets to the west are unlikely to be related to mineralisation based on the lack of response on the reconnaissance lines.
o If drilling were to be considered, it is suggested 2-3 section traverses NW of workings, with one to the SE of workings will define potential of immediate area of the workings.
o Two reconnaissance drill traverses should be completed: first ~400m NW of workings testing for extensions and the second ~800m NW of workings testing the strong multi-element geochemical response.
Naheed Memon, CEO of Oracle, commented:
"It is great to get final results from the maiden geochemical sampling programme at Blue Rocks with anomalies relating well to known mineralisation, with new zones identified to the northwest and southeast of the main working area, that is 320m in strike. Anomalies have been highlighted over the ~2km strike of current work, with drill traverses designed to test the anomalies, with regulatory and heritage approvals required. Next steps are being considered, either to expand geochemical sampling, further geophysics or drill test. I look forward to updating shareholders in due course as we continue work advancing this project."
About Blue Rock Valley Copper and Silver Project:
The Project Tenement:
The Project tenement (the "Tenement") covers 32 Blocks (approximately 102km2) (Figure 1) and is composed of one granted exploration licence, E08/3604. Oracle announced on 11 June 2024 that it had exercised its option to acquire 100% of the tenement. The Tenement was granted on 2 October 2023 and expires on 26 October 2028 but is renewable. The first term is therefore five years with a possible initial extension of five years and further extensions of two years thereafter, with 40% of the licence area to be surrendered at the end of year six.
The Blue Rock Valley Copper and Silver Project (E08/3604) is in the Ashburton Basin, in the northwest region of Western Australia. The site is located 165km southeast of Onslow, the main port for the region's Iron and LNG exports, which is a multi-user port. Access is from the Northwest Coastal Highway on a well-maintained unsealed road. Refer to Figure 6 below for location.
Project Geology
The eastern portion of the Project area overlies the Wyloo Group sediments of the Ashburton Basin which are unconformably overlain by rocks of the Edmund Basin (previously the Bangemall Basin), which cover the western portion of the Tenement. The contact between the Ashburton and Edmund basins is interpreted as being a thrust contact with movement to the west and can be clearly seen in the regional aeromagnetic image.
Mineralisation
The Ashburton Mineral Field (which incorporates the Project area) has a long history of gold, copper, silver, lead and zinc exploration.
Several smaller prospects which were historically exploited for gold, copper, silver and lead are located nearby including the Soldiers Secret and Top Camp gold deposits. Small-scale production of copper, lead and silver has also been recorded in the Ashburton Basin, mainly from the Ashburton Downs copper deposits within the Project area and others in the region such as Kooline (Pb, Ag) and Bali Hi (Cu-Pb-Ag) areas.
