Great Northern Minerals Limited announced that the initial RC drilling program at Douglas Creek has been successfully completed. The twenty hole RC program tested three zones of mineralisation (Zones 1, 2 and 4) and intersected a mineralised low angle structure with widespread disseminated sulphide mineralisation. GNM has also reprocessed historical airborne magnetic data for the Douglas Creek target, and this has highlighted multiple targets, including the presence of a donut style magnetic anomaly (indicative of a porphyry system). GNM has commenced planning on a follow induced polarisation (IP) survey targeting the reprocessed magnetic anomalies, plus the potential depth extensions of the mineralisation intercepted in the recent drilling program. A reverse circulation (RC) percussion drill program was designed to test and define the subsurface nature of the mineralisation at Douglas Creek and the orientation of any containing structure. Three of the anomalous soil and rock targets that produced some of the higher polymetallic geochemistry, namely; Zones 1, 2 and 4, were selected for drill testing. RC percussion drillholes DCRC01-03 were drilled to test Zone 4. These holes intersected a shallow north westerly dipping oxidised horizon from 5 metres containing an increased weight volume % of visible
quartz vein fragments in a pervasive mixed (gossanous) limonite ­ hematite ­ goethite stained and variably sericite + silica altered intrusive host rock mass. A further eleven RC percussion holes were drilled on five cross sections along the Zone 1 target. As per Zone 4, a shallow to moderately south easterly dipping mineralised horizon was intersected of approximate 3 to 5 metres thickness. The down dip drilling intersections displayed an association of increased weight volume % of visible quartz ± epidote ± chlorite veining and accessory pyrite ± chalcopyrite ± arsenopyrite with variable intensity silica + chlorite ± epidote wall rock alteration development within the medium grained equigranular diorite host rock. Six RC percussion holes were drilled on four cross sections over the Zone2 target. As per Zone 1, a shallow south easterly dipping mineralised horizon was intersected of variable 3 to 10 metre thickness. The mineralised horizon was intersected from surface and thus strongly oxidised. A medium-coarse
grained equigranular granodioritic host was intersected with an observable strong pervasive fine white mica (sericite) alteration of feldspar + biotite phenocrysts and groundmass through which a crystalline euhedral quartz ± gossan vein stockwork had variably developed. The drilling intersected a mineralised low angle structure (LAS) with widespread disseminated sulphide mineralisation, with up to 5% visible pyrite and 1% chalcopyrite. The LAS is hosted within medium grained equigranular diorite-tonalite and medium-coarse grained granodioritic intrusions that demonstrates zoned alteration (from potassic to propylitic then phyllic), with a zonation towards phyllic predominant alteration trending north. Material assay results for the Douglas Creek RC drilling program are contained in Table 1. The results returned a variable composite of anomalous Au + Ag + As + Bi + Cu + Pb + Zn ± W
mineralisation associated with mixed sulphides intersected within the LAS. Surface manifestations of this sulphidic LAS had previously returned high grade gold, silver and copper rock chip samples from quartz rich gossanous intrusive outcrop located within the respective soil target anomalies drill tested. The other five soil anomaly target zones that remain untested by drilling, contain similar textural, compositional and geochemical attributes in surface outcrop to target zones 1, 2 and 4. Southern Geoscience Consultants were contracted to re-process open file geophysical data from a 1993
airborne magnetics and radiometrics program completed by Kevron Geophysics over the Camel Creek tenements held by Golden Ant Mining (GAM). The reprocessing was completed and the final report was delivered in late December 2022. A review of the reprocessed geophysical data has highlighted the following targets: Southern magnetic anomaly: Central magnetic low `eye' characterised by a core of quartz + feldspar adamellite containing no magnetite-pyrrhotite-pyrite, surrounded by a magnetic high `donut' characterised by porphyritic quartz + feldspar + biotite + magnetite + pyrite bearing granodiorite-diorite. This pattern could represent a less oxidised porphyry system with a central magnetic low surrounded by an annular magnetic high. Soil Pb anomaly target 6 is located within the magnetic eye low. Central magnetic anomaly centred on soil anomaly targets 1, 2, 3, 4 and 5: A broad NNE trending magnetic low signature of dimension 1.5km x 0.5km developed within a surface expression of equigranular quartz + biotite + hornblende + magnetite diorite (reversed polarity?). Potentially an underlying source porphyritic granodiorite system. Contains soil targets 4, 5 and 1. Peripheral to this magnetic low `core' are linear eastern and western magnetic high signatures which are coincident with soil targets 2, 7 and 1. Soil Target 2 is developed over quartz veined, phyllically altered medium- coarse grained granodiorite country rock. Recently defined soil target 8 located near northern margin of central airborne mag low in contact with a significant magnetic high signature: This soil anomaly target is similarly hosted by equigranular quartz + biotite + hornblende + magnetite diorite. Half of this soil anomaly has a reversely polarised magnetic low - high signature. Northern magnetic low anomaly: GNM exploration personnel briefly visited this anomaly area in Nov. 2022 and collected three rock samples, two of which were of crystalline quartz veining, one of which returned highly anomalous molybdenum assays. This magnetic signature comprises a 1km x 0.7km low containing a 0.3km x 0.1km central lower intensity high `eye'.
