White Rock Minerals Limited provided an update on its in-mine exploration activities at the Morning Star Underground Gold Mine at Woods Point in northeast Victoria. White Rock holds 660km of granted Exploration Licences over the Woods Point ­ Walhalla Geosyncline between Jamieson and Walhalla and two granted Mining Licences (MIN5009 & MIN5299) covering the Morning Star Gold Mine and the Rose of Denmark prospects. The Project is situated approximately 120km east of Melbourne. Highlights: White Rock reports continued exploration success from its ongoing underground diamond drilling campaign at the Morning Star Underground Gold Mine, Victoria. Continued success in the Gap Zone drilling is highly encouraging, with the first pass drilling phase now completed. Two intercepts have assayed greater than 700 g/t gold, with assay results still to be received from a further eight holes. Drill hole 22GZL9016 has returned 0.25 metres @ 972 g/t gold (31 ounces per tonne of gold) in a quartz reef interval with abundant visible gold from the Achilles Reef in the Gap Zone. Final screen fire assays for Gap Zone drillhole hole 22GZL9013 returned 740g/t gold over a width of 0.4 metres. Drilling continues to return positive grades associated with the Dickenson South mining area, supporting White Rock's recent commencement of pre-production mine access activities. Recent results include 31g/t gold over 0.2 metres. Drilling of the Whitelaw target area also returns positive results from recent drilling, highlighting the area as a prospective longer term mining target. Recent results include 31.9g/t gold over 1.1 metres. White Rock's recent drilling program has allowed the Company to complete a geological structural review of the deposit, highlighting several underexplored zones of prospectivity close to existing mining infrastructure. This close proximity to infrastructure allows for short to medium-term drill targeting. White Rock has completed a first pass diamond drilling program targeting the Gap Zone at the Morning Star
Gold Mine. The Gap Zone represents an under-explored area with 200 metres of vertical extent between
areas of historic mining that occurred above 10 Level (>500,000 ounces) and below 14 Level (>300,000
ounces), with historic production1 of 883,000oz gold at 26.5g/t gold.
This first pass drilling phase of the Gap Zone saw 5,380 metres in 26 drill holes completed from four drill
cuddies located across its 600 metres of horizontal extent.
White Rock has received final assay results from the recent Dickenson South and Whitelaw drilling
programs. Results for 24 diamond drill holes totaling 3,140m are reported with hole collars and significant
intersections summarised in Table 1 and Table 2 respectively.
White Rock's immediate objective is a low capital cost restart of gold production from multiple reef locations
at the Morning Star Underground Gold Mine. The existence of an underground mine with infrastructure
already in place (shaft, headframe and winder, dewatering system and off-shaft development) and a gold
processing plant already built, offers the Company a quick pathway to gold production.
Interpretation and follow up drill planning has commenced, in support of the advancing underground
development and pre-production activities at the Mine. The reported drilling also highlights the potential for
further mining areas (Whitelaw) and long-term mine exploration targets within the Gap Zone.
Gap Zone drilling results continue to highlight the high gold grade prospectivity of the Morning Star Mine,
now with two 700+g/t gold intersections at depth (22GZL9013 reported 17 May 20222 & 22GZL9016).
Drill hole 22GZL9016 intersected several veins, with four +2.0g/t Au intersections including 0.25m @ 972g/t
gold and is one of 6 additional Gap Zone holes being reported, all showing prospective economic
intersections since the Company's last Gap Zone release2. Final Screen Fire results for drill hole 22GZL9013
have been received finalising the results from the initial release2 with 0.3m @ 740g/t gold now recorded.
The continued identification of prospective quartz reefs throughout the Gap Zone has allowed the Company
to complete a significant structural review on a deposit scale. The study has highlighted several zones of
prospectivity for continued exploration in the Gap Zone and has provided further insight into the
development and extent of structures in the upper levels, all in close proximity to existing infrastructure.
Logging and Sampling of the Gap Zone drilling is up to date, with the Company eagerly awaiting further
assay results from eight holes.
Final results from the Dickenson South underground target, drilled from surface, continues to support the
Company's decision to commence pre-production work to access this area from 4 Level.
The Surface drilling completed in First Quarter 2022 targeted zones that are prospective for multiple high grade gold
reefs (Dickenson Reef, Exhibition Reef, McNally's Reef, Stacpoole /Age of Progress Reefs, Whitelaw Reef)
proximal to existing underground development infrastructure (Figure 5).
Drillhole 22SDS022 returned a significant result (0.2m @ 31g/t Au) from the Stacpoole Reef, the upper-
most reef targeted for future mining from the Dickenson South project area. This result, combined with the
previously reported holes3, 4, 5 and summarised in the recent release dated 12 July 20226 provides further
information guiding the ongoing development and recommencement of mining operations.
Development access to the Dickenson Reef continues to advance, with planning well advanced for the
establishment of rise access up to the Exhibition and Stacpoole Reefs.
Underground drilling results from 14 holes completed between January to April 2022 targeting the Whitelaw
project area have also been finalised. The drilling was designed to test the structural setting of the Whitelaw,
Kenny's, Campbell and Burns Reefs in the host dyke, with the drilling providing further positive results.
Drillholes 22KPL9001 to 22KPL9006 targeted infill drilling along the northern extension of the historic
Whitelaw North workings. Drillholes 22KPL9007 to 22KPL9014 targeted the southern extension of
mineralisation in a relatively untested region of the reefs to the south of historic mining activities.
Drilling results confirmed the historic drilling to the north and highlighted the prospectivity of the reefs to the
south. The Whitelaw project area provides a longer-term prospect for future mining activities and further
highlights the opportunities hidden within the Morning Star Gold Mine.
