Jeffreys Find RC Drilling Completed - Metallurgical Testwork to Commence
- Assays received for 7 RC holes drilled at Jeffreys Find.
- Intercepts including 5m @ 3.51g/t and 8m @ 2.53g/t Au support the widths and tenor of historic results.
- Samples will be submitted for metallurgical testwork tailored to several toll treatment facilities in the Kalgoorlie and Coolgardie areas
Auric Mining Limited (ASX: AWJ) (Auric or the Company) recently completed an extensive phase of exploration comprising RC drilling programs at Munda, Guest, and Jeffreys Find, air-core drilling programs over the Widgiemooltha Gold Project and soil sampling programs over the Widgiemooltha Gold Project and Spargoville Project.
Results of the different programs have been reported as received, with assay results received for RC drilling in the Guest Prospect reported in October1. Auric has also reported results of RC drilling completed at Munda2.
Assay results have now been received for the RC drilling program at Jeffreys Find which was undertaken during September 2021 with a total of 7 holes drilled for 397m.
Six of the seven holes were drilled as twins of holes drilled by previous explorers with the data from those earlier holes used in the current estimates of resources at Jeffreys Find. The BIF unit that hosts gold mineralisation at Jeffreys Find was intersected in the new holes over the expected intervals and assay results show reasonable correlation with those returned from the earlier holes. These results provide further confidence in the data set used in the resource estimates and will be used as the basis for selection of metallurgical samples for ore characterisation testwork specific to toll mills in the Kalgoorlie and Coolgardie areas.
The 7th hole (AJRC002) was drilled to infill a gap at the margin of the current resource model, confirming the continuity of mineralisation. Hole locations are shown in Figure 2.
Managing Director, Mark English. "Our systematic drilling and assessment of Jeffreys Find has resulted in confirmation of the gold mineralization. It gives us strong confidence of pursuing a cashflow scenario whereby we toll treat our material at nearby facilities. This fits with our Company strategy to bring our assets into development and cashflow as efficiently as possible for the benefit of both the Company and shareholder value."
- (ASX:AWJ): 21 October 2021: New gold zone in the Guest Prospect including 8m @ 3.95g/t Au
- (ASX:AWJ): 26 October 2021: Drilling returns consistent gold results at Munda; 5m @ 4.72g/t including 1m @ 17.11g/t Au and 4m @ 6.23g/t including 1m @ 20.63g/t Au

Jeffreys Find Project
For personal use only
The Jeffreys Find Project comprises mining lease M63/242 and lies around 45km northeast of Norseman in Western Australia.
Gold mineralisation identified at the Jeffreys Find Project includes the Jeffreys Find Deposit and the Neo Prospect around 550 m to the northwest of the Jeffreys Find Deposit. This mineralisation is associated with a moderately south westerly dipping Banded Iron Formation (BIF) unit which is distinctive in magnetic images over approximately 1.6 km. The BIF comprises magnetite-grunerite- chert and is bounded by sandstones, siltstones, cherts and limestones (Figure 1).

Jeffreys Find has an Indicated and Inferred gold resource estimate at 0.5g/t cut-off grade of 1.22Mt @ 1.22g/t for 47,900 oz gold.3 As detailed in Table 1.
Cut off | Resource | Tonnes | Au | Au |

0.5 | Inferred | 0.3 | 1.08 | 10.4 |
Total | 1.22 | 1.22 | 47.9 |

Table 2. Drill Hole Details
Gold mineralisation was intersected predominantly within the BIF unit at depths correlating well with the original drilling. Of the 34 1m intervals that graded greater than 0.5g/t Au, 32 were hosted by BIF and 2 hosted by the bounding sandstone and siltstone units. Significant assays at a 0.5g/t Au cut-off and up to 2m internal dilution are recorded in Table 3.

Significant assays are represented in plan view in Figure 2. Significant assay intervals show some grade variation from the origianal intervals as illustrated in cross section in Figure 3 but are considered reasonable overall.

Development Pathway
Auric is assessing the potential to toll treat gold mineralisation from Jeffreys Find.
For personal use only
Kalgoorlie-based metallurgical consultancy Hardcore Metallurgy have designed a testwork program that will assess the gold mineralisation at Jeffreys Find relative to the grinding and processing requirements at several toll treatment facilities in the Kalgoorlie and Coolgardie area. The latest RC assay results will be used to select samples for testwork and those samples processed in January and February of 2022.
A miscellaneous licence allowing for a haul road connecting Jeffreys Find to the Eyre Highway, 14km to the south of Jeffreys Find is under application with grant expected in the first quarter of 2022.
About Auric
Auric Mining Limited was established to explore for and develop gold deposits in the Widgiemooltha area where previous exploration has largely focussed on nickel mineralisation.
In June 2021, Auric acquired the gold rights to a suite of tenements in the Widgiemooltha and Spargoville areas from Neometals. Widgie Nickel Ltd (ASX: WIN), the 'spin-out' from Neometals, retains the rights to all other minerals. Auric's projects combine these tenements as well as Munda where rights to nickel and lithium minerals are held by Widgie Nickel Limited and Auric holds the rights to all other minerals including gold. At the Jeffreys Find and other Spargoville tenements, Auric owns all mineral rights. The combined tenements cover an area of 102km2 (Figure 5)
