Taruga Minerals Limited (ASX: TAR , Taruga or the Company ) is pleased to present an exploration update for the Mt Craig Copper Project (MCCP), where an extensive reconnaissance exploration and drilling program is ongoing.
CEO Thomas Line Commented: “We are undertaking a vast exploration program at the Morgan’s Creek and Wyacca prospects within the MCCP, which is revealing new insights into the significant potential of the mineral systems identified at the project. We look forward to providing the market with further updates regarding the exciting developments at the project over the coming weeks.”
Wyacca
The diamond drilling at Wyacca successfully intercepted visible copper mineralisation in all 3 holes. At Worrumba 19, blebby to semi-massive chalcopyrite ( Figures 1 and 2 ) hosted within massive dolomite was intercepted in the primary ore zone, which started at 92.5m through to 95.2m, and transitioned into finely disseminated chalcopyrite in shale downhole.

At Powder Hill, in drillhole WCDD002, a gossanous zone was intercepted from 6m, before transitioning into the primary Ore Zone from 18 – 24 metres. The overall alteration zone extended for 18m from 6 to 24m ( Figure 3 ). The primary ore zone is comprised of manganese and iron oxide minerals which contain fine chalcocite banding throughout.

At Worrumba 21, shallow mineralisation was targeted to understand the mineralisation, lithology and structural controls. A 0.55m zone of copper-oxide mineralisation was intercepted from 12.25m, within a dolomite-siderite carbonate matrix. RC drilling has identified broader chalcopyrite-bornite mineralisation downdip of this intercept, and has further identified potential for multiple stacked lenses of copper mineralisation where structures cross cut the Tapley Hill Formation sediments.

Drillhole MCDD003 ( Figures 8 & 9 ) targeted zinc, lithium and REE mineralisation identified from recent RC drilling (RC drillholes MCRC009, MCRC010, and MCRC022) at the Oxide Hill prospect. Heavily oxidised and brecciated sediments known to contain lithium, zinc and REE mineralisation were intercepted from surface. The brecciated marble unit which recently reported the highest grade REE intercepts (up to 0.46% TREO - MCRC009) along the margin of the adjacent dolerite was intercepted from 65.7m to 185.3m end of hole ( Figure 9 ), where the hole was terminated. The drillhole skimmed the edge of the mafic-ultramafic intrusion which is host to the primary scandium and vanadium mineralisation intercepted from surface in MCRC009.

At Hydrothermal Hill ( Figure 5 ), the diamond drill rig recently completed the final diamond hole for the program. So far at Hydrothermal Hill, heavily altered brecciated mafic-ultramafic intrusions and dolomite-carbonates have been intercepted with accompanying serpentine, biotite, chlorite, magnetite, haematite and pyrite alteration ( Figures 11 & 12 ). This alteration zone contacts on the western margin of a diapiric breccia, which the hole was collared into. Sulphides including pyrite and minor chalcopyrite ( Figure 10 ) have been noted within the sediments and mafic-ultramafic intrusions. The alteration identified at Hydrothermal Hill so far is indicative of intense hydrothermal alteration, with the altered carbonates potentially representing contact skarn metamorphism.

Geophysics
Detailed ground gravity and magnetics surveys are currently underway at Wyacca and Morgan’s Creek. The ground gravity surveys are being completed using ATV’s ( Figure 13 , using a 200m x 50m spacing in key areas and 400m x 50m grid spacing surrounding key areas. The ground magnetic surveys are being conducted on foot ( Figure 13 ) over selective portions of Wyacca and Morgan’s Creek, using a high resolution 50m line spacing. The gravity and magnetic data are expected to highlight key structures, intrusions, lithologies and alteration zones which will used in combination with the soils, rock chip and previous drilling data to undertake further precision RC drill-testing. The geophysical data will also be used to conduct inversion modelling of prospective anomalies to assist with drill planning. The Company will present the results of the geophysical program, including new areas of interest to the market shortly, once processing is complete.

All data is stored securely with digital backups. All data entry procedures include data validation. |
|
| Location of data points • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. • All drillhole collars were surveyed after drilling using a handheld GPS. Datum used is GDA94 Zone 54. • Downhole surveys were taken at 6m (collar), 30m and every subsequent 30m drilled with a final survey at end of hole depth. |

| Criteria JORC Code explanation Commentary Data spacing and distribution • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. • Data is insufficient to be used in a Mineral Resource Estimate. The drilling is reconnaissance style exploration with data collected sufficient to guide and define further exploration activities. • Core sample intervals are based on lithological, structural and mineralised boundaries. No sample compositing has been used. Orientation of data in relation to geological structure • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. • The previous and current drilling being reported has identified and defined a variable sedimentary package within the Worumba diapir mega breccia including various rafted blocks in differing orientation. Outcrop of the dolomite metasediments on the margin of the Worumba Diapir and rafted sediments within the diapir assist in drillhole design to best intercept the stratigraphy. • Where possible drillholes are angled towards the interpreted stratigraphic horizon so intercepts are generally reflective of true thickness although some holes drilled in a deliberate orientation to gain perspective of stratigraphic or structural orientation will not be a direct reflection of true thickness. All reported lengths are to be considered downhole lengths unless stated as calculated true thickness. Sample security • The measures taken to ensure sample security. • The samples are collected, processed and despatched by the Supervising Geologist before being sent by courier to Bureau Veritas, Adelaide. Audits or reviews • The results of any audits or reviews of sampling techniques and data. • No audits completed. |

| Criteria JORC Code explanation Commentary Data aggregation methods • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. 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 assay data is being reported at this time. 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 (e.g. ‘down hole length, true width not known’). • Where possible interpreted potential mineralisation widths have been shown on images or noted within the document. Some holes drilled in a deliberate orientation to gain perspective of structural or stratigraphic orientation and as such will not be a direct reflection of true thickness. All reported lengths are to be considered downhole lengths unless stated as calculated true thickness. Diagrams • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. • Appropriate plan and cross section diagrams of collar location, surface features and results are provided in the report. Balanced reporting • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. • All relevant information is reported within the document or included in the appendices if not reported previously. Other substantive exploration data • Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. • All relevant and meaningful recent exploration or known historical exploration data is included in this report or has been previously released. • Recent geophysical programs mentioned in this report include Wyacca undergoing a gravity survey on a 200m x 50m spacing (and broader 400m x 50m spacing), and 50m line spacing high resolution ground magnetics survey. • Morgan’s Creek undergoing a gravity survey on a 200m x 50m spacing (and broader 400m x 50m spacing), and 50m line spacing high resolution ground magnetics. Further work • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. • RC drilling is planned to commence shortly to continue the assessment of conducive rock types for hosting mineralisation and will be planned and guided by ongoing field mapping and soil sample results combined with available geophysical data and geological interpretations. • New and historical data will be combined and used to finalise further programs. |
