Iceni Gold Limited announced the initial drill testing into the Castlemaine Fault, at the Everleigh Well (Everleigh) target area has been completed with 2 DD holes for 997m. The first hole, FMDD0032, successfully tested through the Castlemaine Fault, which has been a significant regional focus for hydrothermal activity and associated alteration/mineralisation events. A 30km segment of the Castlemaine Fault passes directly through the 14 Mile Well project. At this location a number of primary targets are coincident. The targets were developed using a variety of exploration disciplines and include: FMD21 (geophysics), EW27 (geophysics), CSA04 (geology) and 14UF009 (geochemistry). The Everleigh key target area is located on the western contact of the Danjo Monzogranite, classified as a prospective Mafic Group intrusion (Cassidy 2019). This is significant because Mafic Group intrusions are known to be spatially and temporally associated with gold mineralisation in the Kalgoorlie- Kurnalpi Rift. The Everleigh target area formed part of the historic Redcastle gold mining centre which was discovered in 1894. The Everleigh area also contains a number of pits and shafts that were previously explored, 25 years ago, by BHP among others. The Tatong prospect, located nearby, was discovered by BHP as one of many large soil anomalies which were drill tested by Rotary Air Blast (RAB) and Reverse Circulation (RC) drilling. 14 Mile Well project area, showing the seven key target areas. Two diamond drill holes were completed within the Everleigh Well target area, designed to test the Castlemaine Fault and the interpreted Everleigh Embayment.

The Everleigh Well 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 a prominent fault and cross structures, evident in magnetic and gravity data sets. Albite alteration identified in litho-geochemistry. Interpreted Everleigh Embayment on the margin of the Danjo Batholith. Alteration zonation identified in previous exploration vectoring towards the embayment. Historic workings trending towards the structural intersection. Framework for gold mineralisation in the Kalgoorlie-Kurnalpi Rift (modified after Cunningham 2021 and Witt et al 2020). The temporal relationship between gold mineralising events and Mafic Group intrusions in the Kalgoorlie-Kurnalpi Rift. The main gold mineralising event (Early Orogenic ­ Epizonal gold) occurred synchronously with the formation of the regional unconformity and the emplacement of the Mafic Group and Syenite group intrusions. Significantly gold mineralisation is known to be located proximal to the Mafic Group Intrusions and in the Laverton District gold is very strongly associated with Syenite Group intrusions. Diamond drilling was oriented to the southwest (towards 225°), perpendicular to the trend of local stratigraphy and to optimise the intersection of the monzogranite contact and the Castlemaine Fault. This is the first campaign to specifically test the Castlemaine Fault, as it has never previously been diamond drilled. DD Hole FMDD0032 was designed to intersect the Castlemaine Fault within the interpreted Everleigh Embayment geophysical feature. The hole intersected the Danjo Monzogranite and a distinctive porphyritic basalt known regionally in the Eastern Goldfields as "cat rock". In places the basalt displays pillowed textures, indicating it was erupted into water. This is significant because pillowed basalts tend to have increased internal structural disruptions and higher bulk permeabilities. This higher permeability provides ready access for hydrothermal fluids and any associated alteration or mineralising events. The granite and cat rock are cut by a number of felsic to intermediate porphyries. These intrusions are all
altered and contain varying proportions of pyrite and pyrrhotite. This is significant as sulphur compounds in igneous melts have the capacity to transport metals, including gold.
