Shinganda Copper & Gold Project (Zambia)

Shinganda Copper-Gold Project
Galileo entered into an Option and Joint Venture Agreement on 6 December 2021 with Garbo Resource Solutions Ltd. covering the Shinganda Copper-Gold Project, central Zambia comprising Large Scale Exploration Licence No. 22990–HQ-LEL. The agreement gives Galileo the opportunity for new deposit discovery and/or small mine production potential.


The Shinganda project is located in western Zambia just outside the game management area of the Kafue National Park and is easily accessed via the well-maintained dirt road running between Kaoma and Kasempa.


The main feature of interest is the west-northwest Gerhard Trend which extends for at least 12km through the project area. This trend is marked by a strong magnetic linear high coincident with an intermittent zone of silicified hematite and magnetite bedrock containing copper and gold at several places along its length. There are other strong magnetic features of interest on the licence which reflect shallow intrusives, perhaps related to the Hook Granite, suggesting a potential IOCG (iron oxide-copper-gold) setting for the mineralisation seen in the region.

Historic Work
Limited historic drilling has been completed on the project which dates back to 1959. Drillhole WS1 was drilled beneath small workings on a silicified ironstone capping or gossan and reportedly cut a near-vertical zone of heavily veined sediments with copper oxides assaying 1.07% Cu over a true width of 28.3m at a vertical depth of approximately 40-50m and with peak values >2.5% Cu.


A step-back hole, WS5, was drilled beneath WS1 which intersected the same zone over a 75m downhole interval at approximately 150-200m vertical depth, with mineralisation comprising primary chalcopyrite/pyrite sulphide veins of lower grade, with individual samples up to 0.5% Cu. It appears that there is a supergene enhancement in the upper oxidised levels of the structure.


No gold values were recorded although it is known that several mineralised occurrences in the wider licence area carry significant gold values.


Work completed by Vale S.A. on the Gerhard Trend in the west of the property has returned anomalous gold values in drillholes, including a 2m drillhole interval assaying at 3.93% Cu and 1.72g/t Au, and grab samples taken in an exploration pit by Vale S.A in the south of the property reported assay values of 10.45% Cu and 11g/t Au.


Galileo have the right to earn an initial 51% interest in the Shinganda project subject to any necessary Zambian regulatory approval, by spending US$0.5m on exploration and evaluation over two years.


The Company can increase its interest through entering into a Joint Venture to develop a mining operation, ranging from 65% interest for a large deposit of greater than 1Mt of contained copper equivalent, up to an 85% interest in a smaller deposit of less than 200,000 tonnes of contained copper equivalent.


Exploration Completed – Shinganda Outcrop Zone
A ground magnetic survey was carried out in order to provide information on potential structural control along the Shinganda segment of the Gerhard Trend and highlight subsidiary structural trends that might control the Shinganda prospect mineralisation.


During Q3 & Q4 2022 Galileo completed nine angled diamond drill holes for a total of 1,227.2m. The drilling confirmed the Shinganda mineralisation over a plan area of 200m x 100m extending to a depth of 70-80m.


A high-grade core containing inclusions of malachite, probable chalcocite and native copper within a steep sided brecciated hematite gossan was intersected, which measured about 35m wide at 40m depth in drillhole SHDD002. Drillhole SHDD001 clipped the margin of the zone and drillhole SHDD005 confirmed the continuation of the zone to 70m depth, where it becomes less contiguous, however a 25cm interval of semi-massive native copper within hematite was returned at 103m downhole depth.  Drill holes SHDD003, SHDD004, SHDD006, SHDD007 were all step-out holes which returned varied intensities of hydrothermal alteration with associated intervals of copper mineralisation.


A summary of the best intercepts are as follows:
• SHDD002 – 50.3m @ 1.54% Cu, 0.30g/t Au from 21.0m o Including 7.0m @ 4.36% Cu, 1.51g/t Au from 47.0m
• SHDD004 – 43.7m @ 1.01% Cu, 0.18g/t Au from 7.3m
• SHDD005 – 11.0m @ 1.03% Cu, 0.55g/t Au from 102.0m o Including 3.4m @ 2.89% Cu, 1.61g/t Au from 102.0m
• SHDD006 – 16.0m @ 0.72% Cu, 0.04g/t Au from 11.0m

Exploration Completed – Reconnaissance Targets
The company identified a number of additional targets within the licence area for immediate follow-up work, including grab sampling, trenching, pitting.


Nine target areas have been identified to date, designated Target 1 to Target 9, three have been sampled to date, with promising results as summarised:


– Target 1: A small, shallow open pit working, located 5km southeast from the Shinganda outcrop. Bedrock grab samples have returned high-grade assays up to 33.90 g/t Au, with associated anomalous copper. The target shows an east-west anomalous gold trend over a minimum area of 120m by 25m and remains open to the east, west and south and is a priority for further testing.
– Target 7: A relatively large, exposed pit working, located about 5km southwest from Shinganda. A chip/channel sampling programme returned gold and copper values of 3.44 g/t Au and 0.53% Cu and the target remains open in several directions.
– Target 9: A small exploration pit about 4km west of the Shinganda outcrop where soil sampling has highlighted two separate soil anomalies, 500m apart, with pXRF analytical values of up to 409ppm Cu (approximately 10 times background levels).


Further Planned Work


Shinganda Outcrop Zone
An infill ground magnetic survey is planned at a line spacing of 25m to obtain a detailed structural understanding of the area. In addition, a detailed 3D model may be commissioned to plan further drilling, as well as undertaking multielement analyses on selected samples to better understand the mineralogy of the prospect.


Reconnaissance Targets
A field reconnaissance programme is intended to continue over the named target areas in the area surrounding Shinganda, with the aim of testing strike and depth continuity of mineralisation. A stepped programme of soil sampling, pitting and drilling will be planned. It is planned to undertake a re-interpretation of ground magnetic data to better define potential targets and expansion of the soil geochemical survey will test for further blind deposits.
