Summary:
The Katanning gold project (KGP) encompasses a 17km mineralised trend with significant potential across three key zones, which include the following Resource deposits and prospects:
- Northern Zone – Datatine;
- Central Zone – Jackson, Olympia, Jinkas, and Jinkas South;
- Southern Zone – Dingo and Lukin.
Within the Central Zone the Jinkas and White Dam lodes are folded around a quartz monzonite sill; with Jinkas located in the hangingwall of the sill and White Dam in the footwall. The Jinkas and White Dam lodes are the most significant lodes in terms of contained ounces at the KGP. The quartz monzonite forms the core of a major tight NNW-plunging synform, extending over a 5,000m strike length of the Central Zone. Jackson is located proximal to the footwall granite, west of the Jinkas-White Dam lodes.
Within the Southern Zone, the Dingo lode is the primary lode, situated proximal to a footwall granite, and is interpreted to be the southern continuation of the Jackson lode in the Central Lode.
Within the Northern Zone, the Datatine lodes are differentiated from the lodes of the Central and Southern Zones as they are ENE-striking, due to being re-oriented along a major ENE-striking thrust fault. Datatine lodes are proximal to a footwall granite, located to the NNW.
Across the entirety of the KGP, high-grade zones are focussed within fold hinge zones of tightly folded and metamorphosed rocks. These high-grade zones plunge broadly NNW in the Central Zone, SSE in the Southern Zone, and to the ENE at Datatine in the Northern Zone. All mineralised lodes at the KGP are parallel to the primary gneissic foliation and display exceptional continuity along strike and down-dip.
Central Zone
Jinkas and White Dam collectively have 44 defined sub-parallel lodes, striking towards the NNW and dipping at approximately 35° to the ENE. The lodes consist of a defined strike length of approximately 3,000m, dip extents ranging from 50 to 560m and an average lode thickness of between 3 and 5m.
The Olympia lodes represent the northern-most continuation of the Jinkas lode, in a location where grade increases near-surface. Olympia comprises of 25 mineralised lodes, striking towards the NNW dipping at approximately 35° to the ENE. The lodes consist of a defined strike length of approximately 2,200m, dip extents ranging from 50 to 440m and average between 2 and 3m thickness. The lodes have been interpreted to the surface and to a depth of up to 210m vertically. Olympia mineralisation remains open along strike to the north and down-dip.
Jackson comprises of 43 sub-parallel lodes striking towards the NNW and dipping at approximately 30° to the ENE. The lodes consist of a defined strike length of approximately 5,200m, dip extents ranging from 50 to 800m and an average lode thickness of 3m. The lodes have been interpreted to the surface and to a depth of up to 415m vertically.
Southern Zone
The Southern Zone – comprised of the Dingo, Dingo South and Lukin Resource areas – forms the southern strike extension of the Katanning gold project (KGP) structure, with the same mafic host rocks as the Central Zone. Gold mineralisation has been mapped along strike for over 4.5km at the Lukin prospect, with the northern 1.5km of Lukin currently included within the Resource. Lukin is defined by systematic air-core drilling and a coherent 30ppb goldin-soil anomaly over its 4.5km strike length.
Dingo comprises of 35 sub-parallel lodes striking towards the NNW and dipping at approximately 35° to the ENE. The lodes consist of a defined strike length of approximately 2,900m, dip extents ranging from 50 to 420m and average lode thickness of between 2 and 3m. The lodes have been interpreted to the surface and to a depth of up to 270m vertically. Dingo mineralisation remains open along strike to the north and down-dip.
Northern Zone
The Datatine deposit estimates were first reported in the 2018 Resource upgrade and remain unchanged until this estimate. Datatine comprises of 14 sub-parallel lodes striking towards the ENE and dipping at between 40-50° to the SSE. The lodes consist of a defined strike length of approximately 550m, dip extents ranging from 100 to 290m and an average lode thickness of between 3 and 5m. The lodes have been interpreted to the surface and to a depth of up to 400m vertically. Datatine mineralisation remains open along strike to the ENE and down-dip.
