Star Zinc Project Drilling Results

14 May 2018 09:53

For immediate release

 

14 May 2018

Galileo Resources Plc

("Galileo" or "the Company")

Star Zinc Drilling Results

Galileo is pleased to announce results* for the final eight diamond drill holes of its 26-hole drilling programme on the Zambian Star Zinc project ("Star Zinc"), in which the Company has an 85% interest. These holes were drilled in the southern periphery of the historic mineralised zone.

Highlights

 

· Assay results received for the final eight diamond drill holes ("DDH)" of the 26-DDH programme on the Star Zinc project (see Table 1) at depths downhole to 63 metres (m).

 

· These DDHs were mainly proximal to the southern periphery of the historic mineralised body.

 

· Four holes, DDH020 (west) and D DHs 024 to 026 (east) show medium to high grade zinc (Zn) mineralisation from 4.72% Zn to 15.4% Zn.

 

· DDH020 shows 6.21% Zn over 24 metres (m) width downhole (from 31 to 55m downhole) including 14.3% Zn over 8m width. DDH024 shows 5.02% Zn over 26m from near-surface (3 m) including 3m assaying 10.80% Zn from 17 to 20 m. DDH025 shows 8.29% Zn over 29m from surface, including 13m assaying 15.4% Zn.

 

· Independent consulting geologists engaged to develop a conceptual 3D-model and grade-tonnage estimate for the deposit based on the drill data.

 

· Continued presence of germanium (Ge) values, up to 19 ppm (g/t) associated with Zn mineralisation, and up to 47g/t silver (Ag) (in DDH022) recorded in the intersections. Germanium has been trading at $2300/kg ($2.3/g) b

 

* all assays subject to final QAQC analysis

b 07 May 2018 http://www.kitco.com/strategic-metals/ Germanium is used mainly in semiconductors in transistors and electronic, and end uses include  fibre-optic systems, infrared opticssolar cell applications, and light-emitting diodes (LEDs)

 

Colin Bird, Chief Executive Officer, said: "This final batch of results support our view that the project will be boosted by peripheral, at or near-surface, mineralised karsts and zinc oxides. At a cut-off grade of 3% zinc, (based on the fact that the deposit is very close to surface), this would potentially require little or no blasting. We have engaged an independent geological consultant to develop, amongst other things, a conceptual (3D-model) grade-tonnage estimate based on differentiation of the material into medium (3-20% Zn) and high grade (>20% Zn) domains.

We expect from this exercise and futher study to be able to direct the next exploration and drilling programme with a view to further increasing the size of the deposit and to generate a compliant maiden resource estimate To complement this, we are currently evaluating the results from a collection of physical core rock property measurements in relation to potential geophysical exploration methods in order to assess suitability and determination of the most optimal exploration drill-targeting tool.

We will report on the modelling results, which are expected at the beginning of June"

 

Drilling Note

 

DDHs SZDD019, SZDD020 & SZDD021 represent a 2nd fence line through the western core of the deposit. DDH SZDD022 tested the western strike extension. DDHs SZDD024- SZDD026 represent the holes testing the main mineralised zone in the east.

 

Zn mineralisation in the deposit comprises broadly:

 

· in the West, high grade semi massive Willemite mineralisation, vein hosted mineralisation and replacement style mineralisation hosted within dolomitic limestone. Rarer occurrences are breccia hosted and vein hosted within argillite

 

· in the East, haematite- stained argillaceous /shaly limestones hosting mineralisation - typically as replacement style mineralisation with a lower frequency of vein hosted style (compared to the West)

 

· in both the East and West, supergene Zn is present in karsts, fault zones and highly weathered fracture zones as well as associated with ferruginous pisolitic laterite and soil material.

The Star Zinc Project

The Star Zinc project is a historical small-scale open pit mine from where, reportedly, low tonnage, but high grade willemite (a zinc silicate mineral) was extracted intermittently in the 1950s to 1990s.

 

The Star Zinc project is located approximately 18km NNW of Lusaka (see Figure 3.1 below), and is accessible via the tarred "Great North Road" and a good all weather graded road, with the journey time from central Lusaka of approximately 30 minutes (traffic allowing).

 

There is adequate power, water, rail & telecommunications, with the International Airport at Lusaka, less than 45 minutes away.

 

The Mines and Minerals Development Act No. 11 of 2015 , which grants a Large Scale Prospecting Licence provides for an initial 4 years with a further two 3-year extensions totalling 10 years, with a mandatory 50% reduction of licence area at the completion of the 1st grant and 2nd grant periods respectively. The first renewal period initially expired 13 August 2016 but was extended to 13 August 2018. The Company has submitted an application for the next renewal period.

 

The Star Zinc Willemite project was mapped in the 1960s by several geologists of the Northern Rhodesia (now Zambia) Geological Survey.

 

At Star Zinc, two main fracture trends are present, one E - W, and another N - S. Both sets of fractures are nearly vertical and are irregularly mineralised. Willemite generally replaces the host rock marbles in the form of massive ore bodies, but it occurs also in veins

 

In addition, karstic (pertaining to landscape underlain by limestone which has been eroded by dissolution, producing ridges, fissures, sinkholes and other characteristic landforms) mineralisation and red soils (terra rossa) are locally heavily mineralised with detrital willemite and supergene zinc minerals. Zinc values measured in soils at Star Zinc reach up to 15,600 ppm and are accompanied by the pathfinder elements Ag (silver), Pb (lead), Ba (barium), Sb (antimony) and Cd (cadmium). The karst infill has a zinc (Zn) content up to 45wt.% Zn, up to 35wt.% Fe and up to 5g/t Ag.

 

The mineralogical assemblage of Zn nonsulphides includes a whole number of minerals, but the main economic phases present are Zn-silicates (willemite, hemimorphite, Zn-bearing clays), Zn- Pb carbonates (smithsonite, cerussite), hydrated Zn- Pb carbonates (hydrozincite, hydrocerussite) and Zn- Mn- Fe- oxides (zincite, franklinite, gahnite).

 

Limited independent metallurgical testwork by others has clearly shown that the willemite present at Star Zinc is amenable to acid leaching with positive results for two samples tested. Zinc leaching efficiencies obtained ranged from 89% and 92%. The testwork indicated polymerisation of dissolved silica in the leachate.

 

An independent competent person's report commissioned by BMR concluded. In summary, the Star Zinc project has good potential to become a viable project.
