Pilbara Gold and Base Metal Project

Kalamazoo Resources Limited exercised an option (ASX: KZR 6 October 2017, ASX: KZR 17 April 2018) to acquire between 80% and 100% equity in three highly prospective gold projects in WA’s Pilbara region covering 252 km². The tenements, previously owned by companies associated with WA resources industry stalwarts, Denis O’Meara and Brett Keillor, have the potential to host significant gold mineralisation.

Subsequently, Kalamazoo made an additional application (ASX: KZR 10 November 2017) a highly prospective tenements E45/5146 in the Pilbara. The tenement was granted on 16 October 2019.

The projects are within proximity to some of the Pilbara’s most exciting gold projects and located in proximity to the gold projects of Novo Resources (TSX.V: NVO) / Artemis (ASX: ARV), De Grey Mining (ASX: DEG), Venturex Resources (ASX: VXR), Impact Minerals (ASX: IPT), DGO Gold (ASX: DGO) and Calidus (ASX: CAI).

DOM’s Hill Gold Project

DOM’s Hill Gold Project (E45/4722, E45/4887, E45/5146 and ELA45/4919)

The DOM’s Hill Gold Project comprises of three granted tenements and one application and is located 110km south east of Port Hedland.

The project overlies the Warralong, Doolena Gap and Marble Bar Greenstone belts as well as the unconformably overlying Gorge Range Group, the younger Lallah Rookh Synclinorium and the overlying Fortescue Group. The tenements cover the major domain bounding Gorge Range, Muccan South and Bamboo Creek Shear Zones as well as numerous second order shear zones including the Dom’s Hill Shear Zone and the North-East Fault.

The Project is prospective for a large variety of mineralisation styles and commodities. The recent discovery of a significant number of gold nuggets within the Project area, the exploration success of Artemis Resources (ASX: ARV) and Novo Resources (TSX: NVO) in the West Pilbara in a similar geological environment, and the resurgence of gold as a commodity of importance in the Pilbara, warrants robust systematic exploration, initially targeting gold at the site.

The project is considered prospective for a range of gold, nickel, cobalt and base metal deposits. Past exploration has highlighted the potential for shear hosted lode gold mineralisation with a number of advanced targets within the project including DOMs Hill and the North-East Zone.

Within E45/4722 tenement is the Singer Prospect (Figure 5). Great Sandy and prospectors have located up to 300oz of gold nuggets in this zone (refer to ASX: KZR 6 October 2017). No historic drilling has adequately tested this prospect. Assessment of this, and other areas known to shed significant gold nuggets, will be the focus of future exploration.

At the NorthEast Zone Prospect, located east of the Doms Hill Prospect, gold mineralisation is associated with a north-east trending shear zone within a mafic and ultramafic sequence.

As a result of exploration field visits by Kalamazoo and the use of contract metal detecting, Kalamazoo announced (refer to ASX: KZR 17 November 2017) the discovery of a second zone of gold nuggets discovered during early field exploration at the DOM’s Hill Gold Project (E45/4722).

A reconnaissance field investigation was undertaken in late 2019 and Kalamazoo is further encouraged with more gold nuggets being located at two locations within E45/5146 and five locations within E45/4722 (refer to ASX: KZR 2 December 2019).

The Sisters Gold Project

The Sisters Gold Project (80% interest in non-lithium rights E47/2983 and ELA47/4342)

The Sisters Gold Project comprises of one granted Exploration Licence (E47/2983) which covers 136km² and one Exploration Licence application (E47/4342), located 100km south west of Port Hedland. It is prospective for epigenetic gold mineralisation associated with the Mt Wohler Shear, a prospective splay of the gold mineralised Mallina Shear Zone.

Kalamazoo recently announced (ASX: KZR 23 November 2017) further gold nugget discoveries and a gold-in-soil anomaly defined over 3km along the Wohler Shear Zone corridor at the Sisters Gold Project as part of its due diligence process.

Figure 6. The Sisters Project, Pilbara

The Sisters Gold Project lies within a larger area currently undergoing significant gold exploration by TSX-listed Novo Resources (TSX: NVO) and ASX-listed De Grey Mining (ASX: DEG), DGO Gold (ASX: DGO), Coziron Resources (ASX: CZR), Arrow Minerals (ASX: AMD), Venturex Resources (ASX: VXR) and others. The Project contains the north-east trending Mt Wohler Shear, a major splay from the gold mineralised Mallina Shear to the north.

As there has been no reported systematic historical gold exploration along this prospective shear, this provides a significant opportunity for Kalamazoo. The Project is underlain by folded and faulted siliciclastics, volcanoclastics and mafic sills of the Mallina Basin, which is part of the De Grey Supergroup (3020 to 2930Ma).

Planned exploration will target significant new gold mineralisation within the largely unexplored tenement.

Strategically, The Sisters Gold Project is located adjacent to De Grey’s Pilbara Gold Project and within 30kms of De Grey’s proposed new purpose-built processing plant (refer to De Grey’s ASX release “Pilbara Gold Project 20% increase in Resources to over 1.2M0z” dated 28 September 2017).

Known mineralisation within the Mallina Basin includes:

Indee Gold Deposit Style (Mallina Shear) – Orogenic shear controlled vein and lode zones hosted in metasediment. Dominant gold with arsenopyrite and minor base metals. Main spectral response is pyrophyllite, variable sericite (paragonite to phengite) and variable carbonate.
Tourmaline – quartz –sulphide mineralisation – vein sets or “pipes” with anomalous gold – Mt Langenbeck. These zones likely represent high level “pipes” to underlying Indee Suite granitoids. Main spectral response is tourmaline and sericite.
Epithermal gold mineralisation – Associated with the onset of the Mt Roe volcanism. Deposits preserved by flood basalts. Alteration is variable sericite and pyrophyllite.

Gold nuggets were discovered by Kalamazoo (ASX: KZR 23 November 2017) during the early metal detecting program at The Sisters Project (E47/2983).

Nugget discoveries were located south west along strike from the gold soil anomaly and outside the area of soil sampling. Nugget locations are in proximity to mafic intrusions and north-east structures indicating similarities to recent discoveries reported by ASX-listed De Grey Mining at Blue Moon (ASX: DEG 18 October 2017) (Figure 8 & 9).

Following the re-sampling of soil samples initially collected by Sayona Mining for lithium exploration, Kalamazoo announced (ASX: KZR 23 November 2017) a gold-in-soil anomaly defined over 3km along the Wohler Shear Zone corridor and open to the north-east and south-west (Figure 9). This highly encouraging development resulted in Kalamazoo immediately undertaking a follow up dedicated program to determine the optimum soil fraction for detecting an expanded gold anomalism.

The Sisters Gold Project is partly underlain by Mallina Formation sediments, host to recent nugget discoveries by Arrow Minerals (ASX: AMD) (ASX: AMD 7 November 2017) (formerly Segue Resources) in the immediately adjacent E47/3476 (Figure 7).

Marble Bar Gold Project

Marble Bar Gold Project (100% interest in non-lithium mineral rights over E45/4724)

This tenement comprises one granted tenement of 48km² located 6.5km east of Marble Bar and 11km north west of ASX-listed Calidus Resources’ Klondyke Gold Project located within the Warrawoona Gold project area. The southern boundary of E45/4724 is adjacent to Calidus’ tenement E45/4555 which contains the important and high grade Klondyke Gold deposit. Klondyke has reported a JORC (2012) Indicated and Inferred Mineral Resource of 1.25Moz (ASX: CAI 17 July 2019).

Approximately 12km of the prospective Warrawoona Formation stratigraphy occurs within E45/4724.

Limited gold exploration is reported over the tenement area which provides an opportunity to add significant value to this project.

The tenement straddles the western intrusive contact of the Archaean Mt Edgar Batholith and the adjacent basalts, amphibolites and ultramafic units of the Warrawoona Formation. Major northerly trending arcuate regional structures traverse the project.

As reported to the ASX on 2 December 2019 Kalamazoo has completed additional soil and rock chip sampling during the 2019 field season to follow up the soil gold anomaly recently defined in the southern portion of E45/4724 (ASX: KZR 9 October 2019). An infill soil traverse was completed midway between the two original one kilometre spaced lines at 100m spacing along the traverse (Figure 5, 24 samples). Fourteen rock chip samples, mainly of quartz veining, were taken at various locations. Soil samples comprised approximately 0.4kg of -0.5mm fraction, from 150mm depth.
