Revolver Resources Holdings Limited announced the initial Mineral Resource on the remaining area at the Dianne Copper Mine, reported under the JORC Code having a total combined Indicated and Inferred Mineral Resource of 1.62 Mt @ 1.1% Cu. The resource combines a shallow high-grade Primary and Supergene sulphide component encompassed within a broad near-surface lower-grade halo of supergene oxide mineralization. Initial metallurgical tests have shown that the Green Hill supergene oxide mineralization is amenable to low-cost heap leach processing, with the sulphide mineralization amenable to flotation to produce potentially saleable copper and zinc concentrates.

Deposit Characteristics and Mining History: The copper (zinc-silver-cobalt-gold) deposit was identified in 19552 with ongoing exploration leading to the development of a small scale underground and open pit mine operated between 1979-83. Production totalled 69,820 tonnes of high-grade direct shipping ore assaying between 18-26% Cu and approximately 359 g/t Ag.3 The Dianne deposit is hosted in deformed Paleozoic shale and greywacke of the Hodgkinson Formation. Three distinct styles of mineralisation occur: primary massive sulphides consisting of pyrite, chalcopyrite and sphalerite; enriched supergene sulphide composed of pyrite and chalcocite and an associated low grade mushroom shaped halo of supergene oxide copper mineralisation, the Green Hill deposit, comprising stockwork and disseminations of malachite, azurite cuprite, tenorite chalcocite and native copper.

The chalcocite enriched sulphide mineralisation from the massive sulphide zone was the source of the high-grade direct shipping ore that was previously mined at the project. The Dianne deposit has been interpreted as a strataform volcanic massive sulphide (VMS) deposit. Revolver undertook a detailed geological review comprising field mapping, re-logging and petrography, which has resulted in the view that the Dianne deposit is a Besshi-style VMS lens that has been deformed during regional scale folding and locally overprinted by an orogenic quartz vein gold event associated with the Palmer River gold field.

The Dianne massive sulphide was subsequently further modified by Tertiary weathering and supergene processes. Drill Hole Intersection from Validated Historic Drill Hole Database: Down hole (DH) and estimated true width (ETW) copper, zinc, gold, silver and cobalt intersections have been calculated at an 0.2% copper cutoff for the in-ground, unmined portion of the Dianne deposit using the validated historic drill hole database. Pre-mining drill intersections have been "clipped" to the 3D pit and underground void model, with only unmined portions of mineralised intersections reported.

Selected highlights from historic intersections for the Dianne MS and Green Hill mineralisation are presented below. A more comprehensive set of drill intersections, showing the historic validated drilling and the Revolver 2021/22 drill intersections, that together define the validated drill hole database used in the initial Dianne MRE, are presented in Annexure 2, Tables 2a and 2b to give a more complete picture of the grade characteristics of the Dianne deposit. Supergene MS chalcocite-enriched intersections from validated historic holes show high-grade copper with low grade zinc characteristic of the "direct shipping ore" historically mined at Dianne, with best estimated true width (ETW) intersection from holes DMD09 and DMC23 respectively returning: 2.07 m at 27.18% Cu, 0.58% Zn, 493 ppm Co, 0.33g/t Au and 46.1 g/t Ag from 65.76 m; 2.55 m at 20.23% Cu 0.4% Zn, 188 ppm Co, no Au analysis and 19.8 g/t Ag from 49 m. These holes represent remanent MS chalcocite mineralisation that was left unmined in the wall to the drives and pillars that could not be mined at the time of the historic underground operation.

Primary MS intersections show combined high-grade copper and zinc results characteristic of the banded chalcopyrite - sphalerite ore with the best ETW intersections from holes DMD03 and ORC16 respectively returning: 4.89 m at 5.13% Cu, 5.11% Zn, 622 ppm Co, no Au Analysis and 31.1 g/t Ag from 162.15 m; 3.16 m at 5.09% Cu, 7.17% Zn, no Co analysis, 0.13 g/t Au and 38.8 g/t Ag from 158.2 m. Green Hills supergene oxide deposit historic drill intersections have returned broad intercepts of lower-grade copper with little to no appreciable other metals, consistent with the predominately copper oxide and copper carbonate mineral assemblage typical of a near surface supergene and exotic copper deposit. Best ETW intercepts were from historic holes ORC01 and DMC11 respectively, returning 35.48 m at 1.89% Cu from 0.00 m, including 7.43 m at 4.62% Cu from 32.0 m; and 34.26 m at 1.03% Cu from 11.3 m, including 3.64 m at 4.71% Cu from 41.5 m.
