Lyons River is located approximately 1,100km north of Perth and approximately 220 km to the north-east of the coastal town of Carnarvon, Western Australia. The Lyons River Project lies within the Mutherbukin Zone of the Gascoyne Province, which is the deformed and high-grade metamorphic core zone of the early Proterozioc Capricorn Orogen.

Dalaroo’s Lyons River Project comprises a strategic (100% owned) land position of 838km2 within the Proterozoic Mutherbukin Zone of the Gascoyne Province, Western Australia. Lyons River is prospective for, vein/shear related gold, BHT type mineralised base metals (Pb-Zn-Ag-Cu), REE and lithium deposits.

Goodbody Gold System Discovery at Lyons River highlights:

Assays from maiden air-core drill program testing gold-bearing, outcropping quartz veins has outlined gold mineralisation at the Goodbody West prospect, Lyons River Project over a strike length of at least 200m including:

Gold mineralisation at Goodbody West remains open along strike and at depth.

Higher grade rock-chip gold assay results received to date at Goodbody prospect include:

There will be a strong gold exploration focus by Dalaroo during 2024 particularly at Goodbody where gold anomalism extends over a strike length of 6km, and at Turbo Well located 7km east.

Gold mineralization has been outlined in outcropping quartz veins at Goodbody within robust gold in soil anomalies with peak gold values of 132ppb Au at Goodbody West, 93ppb Au at Goodbody Central and 50ppb Au at Goodbody East. The footprint of the Goodbody prospects lies within a broader, 6km long, gold in soil anomaly at 2ppb threshold (refer DAL ASX Announcement from 26 February 2024). 

AC drilling was undertaken at the Goodbody West prospect to test the down-dip extension of surface mineralisation defined through geological mapping and surface sampling completed in 2023.  This exploration work by Dalaroo has identified outcropping, WNW-trending mineralised quartz veins (up to 6.25g/t Au) over 200m strike, hosted within a metasedimentary rock package comprising pelitic schist, chert, ironstone, and BIF (refer DAL ASX Announcement from 28 November 2022).  Veins at surface are typically developed parallel to foliation and locally contain ferruginous oxide phases.

A program of 19 AC holes (867m) was completed on five north-south traverses covering 300m strike, to a maximum vertical depth of 42m (Figure 2).  Significant (> 0.1g/t Au) results from the program included:

LRAC047:  5m @ 0.85g/t Au from 9m, including 1m @ 1.83g/t from 9m

LRAC048:  21m @ 0.21g/t Au from 24m, including 1m @ 0.55g/t Au from 26m

LRAC051:  7m @ 0.36g/t Au from 17m, including 1m @ 1.17g/t Au from 19m

Drilling in the eastern part of the Goodbody West prospect, below the main area of outcropping mineralisation, intercepted several zones of sub-parallel, moderately north-dipping quartz veins, within a sequence of pelitic schist and lesser interbedded psammitic rocks.  Veins are commonly emplaced within or adjacent to high-strain zones and are encouragingly associated with broad widths of silica-sericite (+/- hematite-carbonate) alteration.  Veins contain variable quantities of ironstone and gossanous sulphide.  Primary sulphides are not preserved at the shallow drilled depths.

Higher gold grades, up to 1.83g/t (drill-hole LRAC047) are typically associated with sulphide-bearing quartz veins.  However, broad widths of anomalous mineralisation (e.g. 21m @ 0.21g/t Au in drill-hole LRAC048) may also integrate alteration zones adjacent to vein sets (Figure 3).  Significant Arsenic (As)anomalism, up to 1420ppm is also associated with gold mineralisation.

The identification of sulphide-bearing quartz veins, in association with wide silica-sericite alteration haloes and strong Au-As anomalism from the current shallow levels of drilling are considered indicative of a significant hydrothermal system.  Mineralisation remains open at depth and to the east and requires deeper drilling to assess the potential for structurally controlled high-grade

zones.  It is noted that surface anomalism at Goodbody West coincides with the intersection of WNW and NNE-trending structures (refer DAL ASX Announcement from 8 November 2023).  Such intersection zones represent potential sites of intensified deformation and hydrothermal fluid movement and will be a priority for deeper drill targeting at Goodbody West.

Dalaroo’s Lyons River Project is dominated by rocks of the Proterozoic Age Durlacher Suite which hosts known REE deposits and mineralisation in the Gascoyne Province, including the Yangibana, Yin/Sabre and Mick Well Projects.  A detailed review by a consultant geophysicist of a range of datasets held and acquired, including detailed magnetics, radiometrics (thorium) and ASTER, have outlined 27 targets with potential for REE and carbonatites.

Two significant Rare Earth Element (REE) anomalies have been outlined at View Hill and 32 Mile Well prospects. REE anomalism at View Hill with peak value of 1,043 ppm TREO (Total Rare Earth Oxides) and strike length of 2.2km coincides with large thorium high. REE anomalism at 32 Mile Well with a peak value of 2,025 ppm TREO has a strike length of more than 3km.

REE anomalies lie adjacent to a major NE-trending structural feature, compatible with relationships seen at Kingfisher Mining’s Mick Well REE discovery.  Anomalies could represent hard rock or clay hosted REE mineralisation.

Dalaroo believes the Gascoyne Province is also an emerging Broken Hill Type (“BHT”)/Sedimentary Exhalative (“SEDEX”) deposit setting.

Browns was targeted as one of six significant base metal (Pb-Zn) anomalies in soils identified across the 100% owned Lyons River project through staged systematic soil geochemical surveys. 

Browns represents the second site of Pb-Zn-Ag intersections discovered by bedrock drilling in the Mutherbukin Zone, 5km east of Dalaroo’s Four Corners Pb-Zn-Ag prospect. Combined, the anomalous soil base metal zones span a 30km x 10km area of Paleoproterozoic basin stratigraphy within the Mutherbukin Zone, Gascoyne Province.

 Gossanous outcrops sampled to the east of the AC drilled area at Browns have returned lead (Pb) values of up to 0.53% complemented by anomalous zinc (1140ppm) and copper (420ppm) at the Lyons River Project (Refer DAL ASX Announcements from 31 October 2023). Copper assays of 1.64% have also been recorded from rock chip sampling previously completed at the Four Corners prospect located 5km to the west of Browns (Refer DAL ASX Announcements from 16 March 2022).
