Copper Blow copper-gold Project
The Copper Blow project is located 20km SE of the city of Broken Hill. Copper Blow is an Iron Oxide Copper Gold (IOCG) prospect which hosts high grade copper and gold mineralisation. The project is held under a Joint Venture agreement with Kingfisher as part of the transaction maintaining a 75% interest and Broken Hill Mines 25%. Austin Metals/Silver City has completed 32 drill holes for over 8,400 metres over four rounds of drilling from August 2017 to September 2018. It includes 4,460m of reverse circulation drilling and 4,034m of core drilling. Drilling shows that copper-gold mineralisation occurs as sulphides within a magnetic ironstone, the Copper Blow Shear zone. Additional drilling was completed by Acacia Resources Ltd in 1994 and Triako Resources in 2004.
Following successful drilling results, Silver City Minerals Ltd completed preliminary metallurgical sighter test work in 2018 which indicated copper recoveries of 96% in a rougher concentrate. No Mineral Resource estimate has been completed on the Copper Blow mineralisation. There is over 4.5km of prospective stratigraphy with approximately one kilometre of strike mineralisation effectively tested by Austin and earlier explorers. Mineralisation has been defined over 2 separate zones a North and a South Zone separated by a fault over 600 metres of strike. The Southern zone appears to be characterised by more discrete high grade copper gold zones whilst the north zone is characterised by broader lower grade copper gold grades. Historical shallow RAB drilling between 3 and 12m depth by Rasturn Pty Ltd in 1984 was completed on 300m spaced lines over the 4.5km. A line of deeper RC holes to a maximum depth of 108m was drilled by Triako Resources in 2004 approximately 1.2km North of the historic workings. The drilling especially the RAB is not considered to be drilled to an effective depth to test potential mineralisation given the potential plunge of the mineralisation. Results from historical RC and diamond drilling focussed on the North and South ore zones include:
o 16m @ 2.67% Cu, 0.62 g/t Au and 4.04 g/t Ag from 133m in 84DDHCB06
o 4m @ 6.13% Cu, 4.23 g/t Au and 12.93 g/t Ag from 188m in 17CB041

(EL 8075 75% KFM, EL 8077 100% KFM, EL 7300 85% KFM and EL 8495 100% KFM)
Located between 10-40km NNW of Broken Hill the projects are located in and around a number of historic mines associated with the Parnell Formation of the Broken Hill Group with a particular focus on the historic Allendale mine. The lithologies seen at Allendale in mapping and historic drilling include a garnet biotite gneiss, amphibolites and both metamorphosed psammitic and pelitic sediments. Late pegmatites crosscut the sequence as is seen elsewhere in the region. Mineralisation is characterised by base metal sulphides hosted in what was referred historically to as “lode rock’ and is made up of bluish granular quartz and a garnet quartzite. Exploration was undertaken from the late 60’s and North Broken Hill Ltd carried out a limited diamond drilling program around the old workings in 1969 targeting IP anomalies and a major sulphide body. Best results were in DDHA1 which returned 2.7m @ 12.7% Pb+Zn and 55 g/t Ag from 67.5m. Silver city undertook RC drilling in 2011 with best results including:
​
o 10m@16.1% Pb+Zn and 29 g/t Ag from 15m, inc. 1m@ 38.3% Pb+Zn and 80.1 g/t Ag from 15m and 2m@ 33.8% Pb+Zn and 43.3 g/t Ag from 18m in RCAN002
o 2m@ 19.9% Pb+Zn and 39.2 g/t Ag from 47m in RCAN011
o 2m@ 13.8% Pb+Zn and 51.1 g/t Ag from 117m in RCAN016
o 3m @ 13.2% Pb+Zn and 31.0g/t from 78m in RCAN019
​
Kingfisher sees the opportunity to review the historic drilling at all these prospects and focus on smaller scale high grade opportunities where the silver tenor is higher.

Broken Hill- Yalcowinna Copper cobalt prospects (EL8078) (100% KFM)
The Yalcowinna tenement package is located 30 kilometres to the northeast from Broken Hill and extends for over 25 kilometres of strike with historic rock chip sampling indicating a belt of copper and copper-cobalt occurrences. The area has old workings at several prospects and been the subject of historic drilling predominantly shallow RAB however limited deeper RC drilling has been undertaken around Mt Brown and Fairy Hill workings and gossan, with broad low grade copper intersected at Fairy Hill . Copper mineralisation was previously identified during field mapping by the NSW Geological Survey and former explorers. Multiple gossans remain untested.

Wellington Copper-Gold Project (EL 8971) Macquarie Arc, NSW, 100% KFM
Located in the Macquarie Arc within favourable volcanic stratigraphy, the key prospect is the Willunga prospect located 15km away from the Boda/Kaiser porphyry-copper deposits owned by Alkane, which hosts an estimated Indicated and Inferred Mineral Resource containing 8.3 Moz Au and 1.5Mt of Cu*
​
All of these prospects were explored by Placer in the late 60s with Placer defining a 1200m long copper anomaly with peak values up to 2,000 ppm copper hosted in andesite at Willunga. A continuous 50 ppm molybdenum anomaly was also defined over the eastern end of the copper anomaly and had peak values of 80ppm molybdenum. Limited surface workings were identified in mapping by Placer and no records of historic production are cited. A summary from the 1968 Placer exploration report states: “Interest was focussed on the property by copper mineralization – mainly malachite and azurite in old gougings in the andesite. Pyrite, chalco-pyrite, chalcocite, and molybdenite are also present in smaller amounts, in most cases in quartz. A dump, however, contains appreciable molybdenite and chalcopyrite in granitic material”. (Placer 1968)
​
2 diamond drill holes were drilled by Placer in 1967 targeting geochemical anomalies and IP targets.
D.D.H. W1 was drilled -at 40-degree dip to azimuth 040 to approximately 108.5m total depth, the hole intersected andesite with sporadic chalcopyrite and less molybdenite and went into aplite dykes and granite to the end of the hole.
​
D.D.H. W2 was drilled at-45-degree dip to azimuth 040 to approximately 215m total depth, the hole intersected sheared and foliated andesite with minor chalcopyrite before grading into greywacke and siltstone with more significant sulphides as pyrite and minor chalcopyrite over 7 metres from193m downhole. Eighteen samples were taken with no gold and very low copper and molybdenum values results returned. A spectrographic scan was undertaken on a 3m interval from 154 metres downhole and returned 238ppm Cu, 2ppm Ag, 8ppm W, 40ppmTe and 45ppm Sb.
​
It was concluded from this work was that no further exploration was considered warranted at this time. Interestingly Boda was evaluated at the same time and the same conclusion was drawn, whilst more work was undertaken on the Kaiser deposit Placer did not consider it to have the potential to be of a scale that warranted further attention at that time. (Placer 1968).
​
The broader tenure has been covered by regional scale stream sediment sampling which assayed for base metal suites, minimal precious metal gold and silver assay and limited multi-element trace element geochemistry. Limited RAB, cable and mud rotary drilling was undertaken on the western tenure. Kingfisher considers this project to still represent an exciting early-stage exploration play and proposes to undertake initial ground-based geophysics to identify any potential targets for drill testing at Willunga. ANT ambient noise tomography has been effectively deployed elsewhere in the region to assist in targeting mineralisation

Tindery Gold Project (EL 8579), Cobar, NSW, 100% KFM
The tenement lies on the eastern margin of the Cobar Basin which is part of a larger Siluro-Devonian rift system. Most of the area is underlain by highly deformed and metamorphosed siltstones, sandstones, conglomerates and cherts of the Girilambone Group. These are intruded by muscovite-biotite granites of the Tinderra Granite.
​
A number of significant gold occurrences are present south of the tenure on the Chesney Fault which strikes into the southern part of EL8579. There are a number of faults within the tenement which are considered prospective for evaluation for gold mineralisation.
​
These include the historic Golconda mine, with historic mines department records stating that three shafts (depths 30, 70 and 80ft) Were sunk in 1905 on "lines of reef" which appear to parallel the cleavage, and strike at 225 to 235 magnetic. The main line of old workings “lies in a 50m wide zone of discontinuous alteration", this is where a 50m wide up to 300m striking zone of quartz stockwork is present within chlorite altered sediments and has not been drill tested. Samples from historic dumps at Golconda graded as high as 2.5ppm Au.
​
Limited Drilling in the north-east of the tenement is concentrated over the gold occurrences of Chesneys Folly and Tinderra Tank. The Tinderra Tank prospect was RAB drill tested by Dominion in 1993 with peak gold values of 0.83 ppm. A water bore drilled by CSA was completed in 2018 and sampled by SCI however no significant results were returned. The Golconda mine which does not appear to have been drilled and the Chesney’s Folly prospect present opportunities for drill testing following further soil geochemistry and on ground assessment.
