Ragnar Metals Limited’s (ASX: RAG) latest assays have confirmed Ni-Cu-Co mineralisation matching previously reported visual sulphide estimation in the recently completed the diamond core drilling programme to further test the Granmuren nickel-copper discovery. Granmuren is located within the company’s 100%-owned Tullsta Nickel Project in Sweden, 110km NW of Stockholm.
Initial assay results have been received for the priority rush samples which contained semi-massive sulphides at the base of the Granmuren gabbroic intrusion which returned a length weighted average of 2.86m @ 1.14% Ni, 0.38% Cu & 0.08% Co from 442.00-444.86m.
The assays returned anomalous Ni-Cu-Co mineralisation confirming the visual estimatescfor this section as reported in late September 2022.
The remainder of the hole is being processed at the laboratory which has considerable delay times, driving Ragnar’s decision to put these samples in as a priority in order to verify whether laboratory assay results supported the visual field estimations at depth.
The remaining laboratory assays from the hole, including intervals for which visual estimates of sulphide mineralisation were reported, are still to be received. Those assay results must be received to determine the widths and grades of mineralisation at other intervals in the hole.
Drilling Update
Stage 1 and 2 drilling is now complete at the Granmuren Ni-Cu-Co discovery with 2,562.75m drilled during the campaign. The programme provided valuable information about the sulphide formation and deposition within the Granmuren Intrusion, leading to the development of the company’s ore-forming model, identifying the Central and Basal zones as well as the northern contact as the most favourable locations for the deposition of higher-grade Ni-Cu-Co sulphides
The sulphide mineralisation in hole 22DDTS010 displays typical disseminated, interstitial, matrix, semi-massive and vein style sulphide mineralisation over broad zones. It was drilled to the south of hole 21DDTS007 to determine the 3-dimensional nature of the mineralisation, to intersect the basal contact to the south and to test the northern contact higher up in the intrusion.
The intersections of the extensive magmatic sulphide support the potential of the Granmuren intrusive system to host a substantial Ni-Cu-Co deposit in the Sala District of Sweden.
DHIP-R geophysical surveying of the holes has been completed with GeoVista currently processing and interpreting the model in combination with the previous DHIP-R data.
DHEM down a number of key drill holes has been scheduled and will be completed in the near future. The results of the geophysical survey data will provide a more concise model and controls around the deposition of the sulphide system which will allow for accurate targeting of the massive sulphide accumulation within the intrusion.
