Assessment of results and targeting underway
Ausgold Limited (ASX: AUC) ( Ausgold or the Company ) is pleased to provide an update on exploration activities at the 100%-owned Woodanilling Project which lies 20km north of Katanning, located 240km southeast of Perth, Western Australia.
Past exploration at Woodanilling has targeted layered vanadium – magnetite mineralisation associated with a large complex of gabbroic intrusions. A review of this earlier work has identified four priority areas with anomalous copper – chrome – gold – PGE in auger and past drilling. Ausgold completed a program of 17 RC drill holes for 2,540m and two diamond drill holes for 220m, partly funded by the Western Australian Government’s Exploration Incentive Scheme (EIS) Round 20 (Table 1).
Management Comment
Ausgold Managing Director, Matthew Greentree, commented:
“The recent re-evaluation of the Woodanilling Project’s new exploration drilling has identified potential for a significant mineralised system at Mine Hill, the first hole within the Project having 1.3% copper and 12.6g/t silver with elevated gold, zinc bismuth, cadmium, cobalt, titanium and zinc. This style of mineralisation has not been previously reported in the area and has the potential to add meaningful scale to Ausgold’s portfolio.
Drilling at the Red Hill – Martling areas has intersected gabbros which are enriched platinum and palladium (up to 67 ppb Pd). The highest grades are associated with pyrrhotite and chalcopyrite in RC and diamond drilling which has been conducted over a 6km strike length. This first phase of exploration drilling has shown the Woodanilling layered intrusive complex to be highly enriched in metals including copper, silver, and gold and has potential for PGE mineralisation with further evaluation of this area which is currently underway”.
“Woodanilling is a prospective addition to Ausgold’s exploration portfolio in the Katanning Region. Our main focus is our 100% owned Katanning Gold Project, where Ausgold is finalising the upgraded Resource estimate to be announced early in the coming week.”

Mine Hill copper-silver-gold mineralisation
Diamond hole RHDD001 drilled for 180.6m at Mine Hill, near to historic gold workings intersected a high-grade zone of copper – silver – gold mineralisation. Mineralisation occurs in two near surface zones with semi-massive sulphides including pyrrhotite, chalcopyrite, pyrite and rare trace molybdenite.
Significant intercepts include:
-
1.95m @ 6.65 g/t Ag and 0.70% Cu, including 0.45m @ 12.2 g/t Ag, 1.37 % Cu and 0.14 g/t Au from 56.05m
-
4m @ 1.8 g/t Ag and 0.11 g/t Au from 0m
High-grade Ag-Cu intercepts occur within a broad zone of lower grade mineralisation which extends for over 34.75m and is associated with disseminated sulphides including pyrrhotite, pyrite and molybdenite with elevated values for Cu, Ag, Au, Bi, Ca, Co, Mo, Rh, Ti and Zn. Mineralisation is hosted within a gabbro with the highest grades being along the contact with a granite. Within these gabbros elevated V2O5 -and TiO2 was intercepted with 24.1m @ 0.22% V2O5 and 4.23% TiO2 from 131.5m, including 3.3m 0.71% V2O5 and 12.37% TiO2 from 145.8m.
This new drilling has demonstrated a new style of mineralisation which may have more regional implications. Ausgold is currently reviewing the recent drill results and ground-based geophysics to develop and prioritise new drill targets.
Regional Ni-PGE targets
New drilling by Ausgold (16 holes for 2,581m) has tested three targets identified from anomalous nickel, copper and chromium in surface geochemistry, showing the presence of layered mafic intrusive rocks and elevated PGE’s in past drilling. The enrichment of Cr – Ni and Cu in soils was used to identify ultramafic portions of the Woodanilling layered intrusion, which are the likely hosts for potential Ni-PGE mineralisation. A broad zone over 6km of strike length with anomalous Pt – Pd is enriched in Cr, Cu and Mo, with magmatic chalcopyrite and pyrrhotite noted within a coarse-grained gabbroic rock at Red Hill.
Martling
Nine RC holes for 1,117m were drilled to target anomalous Cu, Ni and Cr values in historical auger soils and to test an area with strongly anomalous platinum (up to 45 ppb Pt) and palladium (up to 50 ppb Pd) over 56m down hole in historical drilling (drill hole 08KTR077 – ASX Release 13 December 2018). New RC drill hole RHRC009 has intersected this same zone of enriched PGE – Cu with disseminated sulphides including pyrrhotite and pyrite over a total depth of 73m and elevated Pt (up to 48 ppb) and Pd (up to 62 ppb), Ni, Cr (800 - 980ppm).
Red Hill
Eight RC holes at the Red Hill (RHRC011 - 16) drilled for 1,335m and one 70.2 m diamond tail (RHR016D). Ausgold’s drilling has targeted areas with potential ultramafic rocks, focusing on areas with high Cr values (800 - 980ppm) identified in historical auger sampling. New drilling intersected biotite - garnet gneiss, gabbro and minor granites with the gneissic unit contained relatively high levels of chromium up to 571 ppm.
Hole RHRC014 diamond tail was drilled from 180 to 250.2m which intersected coarse grained ferro-gabbro. Sulphides were intersected in the diamond tail between 129-135m and at 179.9m with a 2cm wide sulphide bands which include chalcopyrite and pyrrhotite intersected within a coarse-grained gabbro.

Wilhelm’s Hill
One RC hole for 200m RHRC017 was drilled to test a geophysical (aeromagnetic) target 3.5km west of Red Hill. The target is a modest-sized gabbro sill with drilling intersecting almost 200m of gabbro.
Although the palladium and platinum values in RHRC009 are not of economic grade they are highly anomalous compared to average gabbroic values (typically gabbro has less than 10ppb Pt and Pd). The enrichment of Pt-Pd along with the presence of magmatic sulphides justify further work in this area.

Reported results are all from 100% owned Ausgold Exploration Pty Ltd Mining Tenements (wholly owned subsidiary of Ausgold Limited), including E70/4863, E70/5142, E70/4864, E70/5223. The land is used primarily for grazing and cropping. The tenements are in good standing, and all work is conducted under specific approvals from the Department of Mines and Petroleum (“DMP”). Apart from reserved areas, rights to surface land use are held under freehold titles. Ausgold has entered into access and compensation agreements with freehold landowners that permit exploration activities. Only registered Aboriginal Heritage Site 35607 known as “Boyerine Reserve Burial” which is located on the north eastern corner of E70/4863 occurs over the tenement package. This heritage site lies within a reserve as well. The following reserves occur on the tenement package and will limit / hinder exploration activities, R 28471, R 25243, R 25242, R 13145, and R 20987. The tenements also cover the following town sites which will limit / hinder exploration activities Woodanilling, Boyerine, Moojebing, and Pinwernying |

Vanadium Mineralisation was first noted around 1930 in the Mine Hill area some 25km NW of Katanning. No other occurences of magnetite were recorded in the district until Otter Exploration geologists discovered titanifeous magnetite 6 km south east of Katanning in March 1980. Otter and AK Minerals (early 1980s):- which included ground and airborne magnetic surveys, geological mapping . The airborne survey helped to outline magnetic anomalies at Martling Farm, Mine Hill and Red Hill.

Platinum Australia Limited (2005-2006):- carried out a
database compilation of previous work, plus stream
sediment sampling, mag-lag sampling, aerial photo
interpretation and regolith mapping. This exploration
programme was orientated towards the platinum group
metals.
Accent Resources NL’s exploration programme was
focused towards the discovery and evaluation of
vanadium-titanium-magnetite occurrences. The work
included remote sensing, an airborne radiometric and
magnetic survey, geological mapping and sampling and
metallurgical test work.
A detailed aeromagnetic and radiometric survey
commissioned by Accent Resources NL was flown over the
Katanning area in September/October 2007. The purpose
of this survey was to pinpoint highly magnetic areas
indicative of potential vanadium-titanium-magnetite
deposits.
Geology Deposit type, geological setting and style of The geology in the project area consists predominantly of
mineralisation. fresh granite and minor metagabbro and metadolerite.
Extensive laterite cover occurs across much of the
combined license area. Anomalous vanadiferous
titanomagnetite occurrences are located in the region
associated with a titanomagnetite gabbro intrusive and a
gold working at Mine Hill
