Galileo Mining Ltd (ASX: GAL, “Galileo” or the “Company”) is pleased to announce moving loop electro-magnetic (MLEM) surveying has delineated highly conductive targets beneath the Subzero Copper Prospect near the town of Norseman in Western Australia.
The MLEM survey was completed over an area where earlier prospecting and mapping had identified a high-grade copper gossan.

The company has recorded copper grades up to 19.9% from surface oxide breccia samples with further iron rich gossan samples assaying up to 1.1% copper.[(1)]
Galileo Mining Managing Director Brad Underwood said: “ The Subzero Prospect represents a classic drill target with a copper rich gossan on surface underlain by a conductor at depth. The magnitude of the conductor suggests the possibility of a large mineralised system and we plan to commence drill testing the area in August. Galileo is an active and well-funded mineral explorer that aims to make discoveries to create value for our shareholders. Previous explorers focussed on gold and nickel exploration around Norseman providing us with the opportunity to drill an untested copper target with potential for considerable value creation.”
The MLEM survey, which utilised 400 metre loops and a Jessy Deeps SQUID in a Slingram configuration, has identified conductors over 2.1km of strike length. Conductive rocks are frequently targeted in copper exploration as the sulphide minerals that can host copper provide an excellent response to electro-magnetic geophysical techniques.

The Subzero conductors match the location of prospective volcanic rocks mapped in the field and are particularly noteworthy given their relationship with the copper gossan on surface. Sub-surface drill testing can now be directed towards the source of the conductors to determine the economic potential of the rocks at depth.
An initial RC drilling program is scheduled to commence in August 2019 with drill holes planned to test beneath the copper outcrop and into the top of the conductor at approximately 90 metres below surface.

Pillow basalts have been mapped to the west of the copper outcrop which is hosted in a silicified volcanic sediment. To the east a gabbro appears to have intruded the volcanic sequence. No straightforward evidence of facing direction exists with the dip of the rocks generally subvertical to the west. Cross structures have been interpreted from a recently flown detailed 50m magnetic survey and may represent zones of fluid flow.
Modelling of EM data has shown two strongly conductive zones along the prospective contact position at the Subzero Prospect. The northern model is over 1,500 metres in length with the top of the model varying between 90 and 110 metres below surface. The model dips at 88 degrees to the west, extends over 600m below surface, and has a modelled conductivity thickness of 11,000 Siemens.
The southern model is over 800 metres in length with the top of the model varying between 80 and 110 metres below surface. This model dips at 82 degrees to the west, extends over 400m below surface, and has a modelled conductivity thickness of 12,100 Siemens.
The modelled conductivities are consistent with those expected from massive sulphide sources however Volcanogenic Massive Sulphide systems can occur within conductive host rocks and additional targeting may be required to locate zones with the most potential for economic mineralisation.
The first RC drilling program will test for copper oxide mineralisation beneath the gossan and test the modelled EM conductor at a position closest to the copper rich outcrop.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |

| Geology | • Deposit type, geological setting and style of mineralisation. |
•The target geology and mineralisation style is volcanic hosted massive sulphide (VHMS) mineralisation occurring within the GSWA mapped Mount Kirk Formation •The Mount Kirk formation is described as “Acid and basic volcanic rocks and sedimentary rocks, intruded by basic and ultrabasic rocks” |

•No drilling reported | |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal _equivalent values should be clearly stated. _ |
•No assays reported | |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width _not known’). _ |
