VANCOUVER, BC, Jan. 25, 2022 /CNW/ - Outback Goldfields Corp. (the "Company" or "Outback") (TSXV: OZ) is pleased to provide an update on exploration activities at its Yeungroon property, central Victoria, Australia.

"We are excited to resume our exploration program at our Yeungroon property, located in the heart of the Victorian Goldfields. Results from exploration on the property to date indicate that the Golden Jacket mine is part of a much larger system that we now know extends along strike well beyond the limits of historical mining," commented Chris Donaldson, CEO.

"Our multi-rig program has consisted of shallow diamond drilling peripheral to the historical Golden Jacket mine as well as widely-spaced and grid-based RAB holes along strike to the south. An air core drill rig is being mobilised to the property to follow up on prospective targets to the south as well as investigating new targets northwest and northeast of the Golden Jacket mine."

Highlights

• Exploration is ongoing across the Yeungroon Gold Property: A combination of grid-based RAB and focused diamond drilling has confirmed the presence of an open-ended, reef-hosted gold system at Golden Jacket.
• Just beginning to "scratch the surface" along the Golden Jacket fault: Only 1 kilometer of the +30 kilometers of prospective strike length has been investigated with the RAB drill and follow-up targets are already defined.
• Significant air-core drill program to commence with two primary objectives:
• • Expand and test at depth the 600 meter long, open-ended, near-surface arsenic anomaly south of the Golden Jacket mine.
  • Test numerous priority geophysical targets located northeast of the Golden Jacket mine.

Golden Jacket Drill Program

The Golden Jacket mine is associated with the property-scale, northwest-trending Golden Jacket fault, which transects the property for over 30 kilometres of strike length. Historical small-scale production from the Golden Jacket mine was reportedly 1,400 ounces of gold at approximately 250 grams per tonne¹. 

Air-core drilling will focus on testing the northwestern extent of the reef-hosted gold system along strike from the Golden Jacket mine, as well as testing numerous geophysical targets to the northeast (Figure 2). The air-core drill program is designed to build on encouraging results from a large grid-based, top of bedrock sampling rotary air-blast (RAB) drill program, and a short diamond drill program (Figure 1). Similar to RAB drilling, the air-core drill rig is used to sample and map the "top of bedrock" below cover.

The Golden Jacket drill program is being completed in two parts:

1. The first phase of the program utilised a RAB drill to complete a tight grid of holes, on 20-metre centres, peripheral to, and along strike to the southeast from the Golden Jacket mine. Grid lines were northeast-oriented and spaced 60 to 120 metres apart (Figure 1). Additional wider-spaced holes, east of Golden Jacket were also completed (Figure 1). 279 holes have been completed to date.

Top of bedrock samples were analyzed using a tailored portable Xray fluorescence spectrometer (pXRF) workflow to measure elemental concentrations from prepared sample mounts as well as QA/QC samples in the field. Samples were prepared and analyzed daily. Preliminary pXRF data highlight a broad, 600 meter long, northwest-trending, high-arsenic anomaly. This anomaly is along strike from the Golden Jacket mine to the southeast (Figure 1). The relationship between gold mineralization and disseminated arsenopyrite and high-arsenic contents in host rocks peripheral to gold-bearing quartz reefs is well established throughout the Victorian Goldfields (e.g., Arne et al., 2008) and has been used to focus exploration and vector to high-grade mineralization.

Select samples from RAB holes with elevated arsenic contents were also submitted for fire assay analyses. Hole OGR013, located 300 meters south of the Golden Jacket mine, intersected 1 meter of 1.5 g/t gold from 22 meters down hole (Figure 4), which suggests the gold system extends southerly beyond areas of historical mining.

The northwest-extent of the anomaly, as well as interpreted northeast offsets and multiple additional targets, will be investigated with the air-core rig during the current program (Figure 2).

2. Nine diamond drill holes for 1,025 metres have so far been completed at the Golden Jacket mine and, based on the presence of sulfide-bearing quartz reefs and preliminary assay data, more holes are planned. The purpose of the drilling was to investigate the structural setting and geochemical footprints of high-grade gold mineralization along strike and below the historic Golden Jacket mine (see news release dated August 25^th, 2021). The drill holes to date have covered a northwest-trending strike extent of 100 metres and have tested down to 115 metres depth (Figure 4).

Of the nine completed holes, four were terminated short of their target depth due to the presence of historical mine workings and voids (Figure 4). This suggests that historical underground developments are more widespread than government records indicate. Hole OGA0015, however, intersected 4.7 meters of 1.15 g/t gold including 0.7 meters of 4.01 g/t gold below the upper level of modelled workings (Figure 4). Gold mineralization in this area is associated with arsenopyrite-bearing quartz veins within broad zones of disseminated arsenopyrite hosted in deformed sedimentary rocks.

Updated modelling of all intersected quartz-reefs and the location of newly identified mining voids has led to the creation of new drill targets. These targets, both along strike and down-dip of the Golden Jacket system, will be ranked and prioritised together with results from the upcoming air-core program.

Yeungroon Project

The 698 km² Yeungroon property is transected by the north-trending, crustal-scale Avoca fault, which separates the western Stawell zone from the Eastern Bendigo zone. The western side of the Yeungroon property contains the historic Golden Jacket hard-rock reef mine associated with the regional-scale, northwest-trending Golden Jacket fault. Historical mining records indicate the Golden Jacket mine produced quartz-rich ore with grades of up to 250 grams per tonne gold (Bibby and More, 1998), however, the vertical and lateral extent of mineralization remains unknown. 

The eastern side of the project is underlain by Ordovician rocks of the Castlemaine group and comprises the northern extent of the Wedderburn Goldfield, where numerous small-scale, historical alluvial and hard-rock mines are located.

Community Engagement

Outback recognises the importance of open and honest community engagement in all our exploration activities. We approach all our exploration activities in a sustainable manner and ensure our activities comply with the Victorian Code of Practice for Mineral Exploration.  As such, community consultation with local landowners has commenced and is ongoing.

Quality Assurance and Quality Control

All sample assay results have been monitored through Outback's quality assurance / quality control (QA/QC) program. Drill core was sawn in half at Outback's core logging and processing facility in Ballarat, VIC. RAB samples were collected in the field. Half the drill core and RAB chips were sampled and shipped in sealed and secure bags to the Gekko Assay Laboratory in Ballarat, VIC. Samples were prepared using standard preparation procedures (dry, crush and pulverise at 75 micron mesh). Gold was analyzed by fire assay on a 30 gram sample with an AAS finish (atomic absorption spectroscopy). Gekko Assay Laboratory is accredited for compliance with ISO/IEC 17025 Testing by National Association of Testing Authorities, Australia (NATA)

In addition to Gekko Assay Laboratory QA/QC protocols, Outback implements an internal QA/QC program that includes the insertion of standards and blanks into the sample stream.
