Ballarat,
White Rock's primary objective at the
The Dickenson South target area is one such primary target with multiple high-grade, gold-bearing reefs.
The surface drill rig has now completed a program of drill holes that assisted in the assessment of near term development and production potential for further working areas close to the Main Shaft; the Age of Progress Reef and Stacpoole Reef, accessed via 2 Level and the Dickenson Reef and the Exhibition Reef that can be accessed via 4 Level (Figure 1*).
Of note, the latest phase of infill drilling from surface has highlighted the potential of the Exhibition Reef to provide an additional working area for the upcoming recommencement of mining activities. Figure 2* highlights the area where a significant "high-grade" zone could extend for more than 100m strike and up to 40m down-dip. The Exhibition Reef "high-grade" target area includes the following intersections:
- 0.2 metres @ 140g/t gold in 22SDS0012A (true width);
- 0.2 metres @ 13.1g/t gold in 22SDS013 (true width);
- 0.4 metres @ 35.9g/t gold in 22SDS015 (true width);
- 0.4 metres @ 12.7g/t gold in 21SDS005 (true width); and
- 0.4 metres @ 21.2g/t gold in L4001 (true width).
White Rock commenced surface diamond drilling at the Dickenson South underground target in late 2021, with results from the first 17 holes reported in January and
Complimenting the results previously reported for the first 17 holes in the program, complete assay results have now been received for a further eight surface diamond drill holes (22SDS012 to 22SDS018, including 22SDS012A). Significant drill intersections from the latest holes are summarised in Table 1* below. All drill assays >1g/t gold from the current program at the Dickenson South target are provided in Table 3*. Assay results are pending for holes 22SDS019 to 22SDS022.
Drilling results have been extremely encouraging, with multiple high-grade intersections across various reefs. These results support the interpretation that there may be an extension of the mineralisation from historic stoping with existing development access near the shaft, through to the southern dyke margin. A three-dimensional interpretation of the reefs is continually being updated and used to inform decisions regarding the assessment of potential working areas and scheduling of development and the anticipated future underground production from multiple quartz reefs.
White Rock is assessing the potential for five gold production working areas, providing a pathway to recommence mining at:
1.
2. Exhibition Reef where an exploration rise will proceed off the Dickenson South development drive and is in progress;
3.
4. Stacpoole / Age of Progress Reefs where development is in place and minor infrastructure requirements will allow mining to commence in the short term; and
5.
Exploration will continue to progress from underground, where the drill rig is currently completing a broad first pass assessment of the
Drilling to date has provided significant encouragement that a number of mineralised quartz reefs are distributed throughout the
Earlier drilling, at the very northern margin of the host dyke, revealed at least 10 quartz reef structures. This first-pass drill program will provide sufficient data to assess and identify those quartz reefs with the greatest potential for more detailed follow-up drilling.
