Iceni Gold Announces Exploration Update on Alteration Identified in Drilling At Danjo Ne
Iceni Gold Limited has 7 key high priority targets within the 14 Mile Well project area. Iceni is actively exploring the target areas using geophysics, Ultrafine (UFF+) soil sampling, air core (AC) and diamond drilling (DD). The 600km2 14 Mile Well tenement package is situated on the western shores of Lake Carey, 50km from Laverton WA. The first phase of diamond drilling at Danjo NE has been completed, with 7 holes for 2,829m. Danjo NE is located within the Danjo Monzogranite intrusion, classified as a prospective Mafic Group intrusion (Cassidy 2019). The target is centred on a large +1km long outcropping, east-west trending thick quartz reef that is situated within an anomalous corridor that links with the TOTK vein 6km to the northwest, within the North-1 Target area. The Danjo NE quartz reef displays a strong Au-Ag-Te geo chemical association. Drilling was designed to follow up significant rock chip anomaliesfrom the Danjo NE quartz reef, which included1: 24.6 g/t Au, 14.5 g/t Ag & 7.33 g/t Te; 5.07 g/t Au, 78.7 g/t Ag & 56.4 g/t Te; 3.67 g/t Au, 4.02 g/t Ag & 25.3 g/t Te. Alteration in FMDD0026, the Danjo Monzogranite is cut by quartz tourmaline-pyrite veins with hematite, pyrite and white mica alteration. 14 Mile Well project area, showing the seven key target areas. Seven diamond drill holes were completed within the Danjo NE target area. Image The Danjo NE area was targeted due to positive field mapping observations made by CSA Pty Ltd. geologists in 2018 and 2020, which includes the following positive geological prospectivity indicators: Presence of prominent fault, evident in magnetic and gravity data sets. Zone of intensely foliated and sericite altered granite with quartz tourmaline veins. Identification of a central deformation zone hosting quartz veining. Substantial amounts of quartz tourmaline veining. is Total Magnetic Intensity (TMI). Reduced to Pole (RTP) (after GSWA).

The close-up image shows the sample hosting fresh pyrite and cavities after sulphides associated with white mica alteration. Similar samples, further along strike, have returned significant Au, Ag and Te anomalism. Danjo NE: Schematic section 407,450mE, where the diamond drilling intersected several zones of quartz, tourmaline and sulphide veins beneath the Danjo NE reef outcrop. The host rock is the Danjo Monzogranite which has been intruded by intermediate porphyries. Drilling intersected zones of strong alteration associated with the quartz veining. The diamond drilling program included scissor holes to gain early structural control (section is looking west). Alteration in the vein selvedge is dominated by white mica and tourmaline needles. This mineral association has been observed at other gold deposits in the Yilgarn. The first half of the diamond drilling program was conducted on three north-south sections, which were designed to intersect and adequately test the easterly trending quartz veins that host the Au bearing rock chip samples. Scissor holes were drilled early in the program to constrain structural controls and optimize the drilling orientations with respect to the geology. The second half of the diamond drilling program was conducted on two east-west sections, which were designed to intersect an anomalous geochemical trend associated with interpreted northerly to northwesterly trending structures. Drilling intersected the Danjo Monzogranite beneath a thin cover sequence. The monzogranite has been intruded by a number of felsic to intermediate porphyries. An interval within hole FMDD0027 has a preliminary identification as a biotite rich lamprophyre. This is significant, as lamprophyres are known to be associated with gold mineralisation in Archean greenstone belts. The larger intermediate porphyry was consistent and could be traced between holes and between sections. This porphyry contains trace sulphides disseminated throughout, which is meaningful because it demonstrates that a sulphide bearing magma with the capacity to carry gold is spatially associated with the Danjo NE quartz reef. The targeted quartz veins were intersected in most holes. The veins have a characteristic mineral assemblage that includes quartz, carbonate, tourmaline, pyrite and white mica. Alteration within the host monzogranite includes silica, carbonate, white mica and pyrite. This alteration is focussed around the quartz veins. These mineral assemblages are common within known gold deposits in Archean greenstone belts. This drilling program is being followed-up with a broader +120 hole/6,500m AC drilling program covering an area 1km x 1km surrounding the main diamond drill target area. Assay results from this drilling program are expected to be received towards the end of First Quarter 2022, with the AC results expected to follow in the quarter thereafter.
