ASX ANNOUNCEMENT
4 February 2021
Aurora Tank Gold
1m assays yield gold over 165 g/t
Marmota Limited (ASX: MEU) (“Marmota”)
Marmota (ASX:MEU) is very pleased to announce that it has received the detailed 1m assay results from the RC drilling program at Aurora Tank completed in September 2020. Initial 4m composite results were reported to the ASX on 4 November 2020.
1. Marmota’s highest ever gold intersection
The new detailed 1m results has yielded Marmota’s best ever 1m intersection of 165 g/t gold , at 66m downhole[1] [ Hole 20ATRC324 ].
To ensure that the outstanding assay of 165g/t gold is not the result of a ‘nugget effect’, Marmota collected 5 separate spearings of the drilling sample bag[2] and then assayed each spear sample separately by fire assay. Fire assays of the 5 separate spearings returned grades of 223 g/t , 154 g/t , 119 g/t , 121 g/t and 212 g/t respectively, yielding an average of 165 g/t gold. Notably, every one of the 5 spearings returned grades over 100 g/t gold, and two of the five spears yielded assays over 200 g/t gold.
1 Approximately 57m from surface.
2 The multiple spearing was carried out for QA/QC purposes, and to better understand the empirical sampling distribution. Page 1
2. This is the fourth drilling program at Aurora Tank in which Marmota has intersected grades of ~ 100 g/t gold (or more) over 1m, and now in 4 distinct areas:
| Grade | Location | Depth from Surface | HoleID | Date of Result |
|---|---|---|---|---|
| **93g/t ** | Central east zone | 32 m | 17ATAC021 | ASX:MEU 4 Sept 2017 |
| 105g/t 3 | Bottom of NW flank | 38 m | 18ATRC104 | ASX:MEU 7 May 2019 |
| 120g/t | South zone | 21 m | 19ATAC049 | ASX:MEU 19 Sept 2019 |
| **165g/t ** | new extension to the NW flank | 66 m | 20ATRC324 | ASX:MEU 4 Feb 2021 |
Figure 5 summarises these results and the different zones. While such numbers are exceptional, at Aurora Tank they appear as a notable and recurring feature of the empirical distribution of gold grades at the Aurora Tank discovery, across multiple zones.
3. New high-grade 1m intercepts over 10g/t gold include:
- 1m @ 165 g/t gold (from 66m downhole) in Hole 20ATRC324 ( 3m @ 61 g/t gold ) 1m @ 41 g/t gold (from 55m downhole) in Hole 20ATRC224 ( 4m @ 13 g/t gold ) 1m @ 36 g/t gold (from 120m downhole) in Hole 20ATRC303 ( 2m @ 21 g/t gold ) 1m @ 30 g/t gold (from 82m downhole) in Hole 20ATRC313 ( 2m @ 16 g/t gold ) 1m @ 14 g/t gold (from 44m downhole) in Hole 20ATRC223 ( 4m @ 7.8 g/t gold ) 1m @ 13 g/t gold (from 51m downhole) in Hole 20ATRC245 ( 3m @ 9.7 g/t gold ) 1m @ 13 g/t gold (from 33m downhole) in Hole 20ATRC242 ( 3m @ 8.8 g/t gold ) 1m @ 12 g/t gold (from 49m downhole) in Hole 20ATRC222 ( 3m @ 7.3 g/t gold ) 1m @ 12 g/t gold (from 54m downhole) in Hole 20ATRC227 1m @ 14 g/t gold (from 78m downhole) in Hole 20ATRC235

4. NW Flank excels
==> picture [318 x 499] intentionally omitted <==
Strike has increased three-fold in 1 year The new NW flank has reported multiple high-grade assays [ see Figures 1, 2 and 3 ]. The NW flank is a new zone discovered in Marmota’s previous 2019 drilling program while following up elevated gold in biogeochemical sampling (tree sampling) [ see ASX:MEU 31 July 2019 and 19 Sept 2019 ] .
One year ago, the NW flank (red-dashed line) was known to extend approximately 95m in a NE direction.
At the end of this program, the NW flank now extends about 3 times that distance (285m) in a north-easterly direction and remains open along strike.
The last hole drilled at the top (north) of the NW flank Hole 20ATRC313 yielded 1m @ 30 g/t (82m downhole) –– and remains open.

5. First high-grade gold at depth + Open to the west and at depth
Marmota has been fortunate to intersect very high gold grades close to surface [ typically just 20m to 50m from surface – see Summary Highlights (p.11) below ]. Importantly, this program is the first time that Marmota has also intersected high grade gold at depths below 80m.
In particular, reconnaissance Hole 20ATRC303 designed to test for an extension to the west of the NW flank intersected 1m at 36 g/t ( 2m @ 21g/t ) at a depth of 122m downhole[4] . Follow up drilling is necessary.
The intersection of 36 g/t Au suggests the presence of high-grade shoots to the west and at depth. The presence of high gold grades at depth is highly encouraging when combined with the reported results from the mineragraphic testwork in May 2020 [see ASX:MEU 21 May 2020 ]. This test work on gold grains sampled from a high-grade gold intersection at Aurora Tank found the gold grains to be predominantly primary mineralisation with the colour indicating high purity gold. If the host mineralised lodes continue further to depth, they are likely to consist of high purity primary mineralisation.

Comment
Marmota Chairman, Dr Colin Rose, said:
- “ I am delighted that this program has produced our new highest ever 1m intersection, at an outstanding 165 g/t … rocketing past all our previous best top intercepts of 120 g/t, 105 g/t and 93 g/t. This is particularly pleasing given that this result was obtained in a predominantly extensional program, testing out new ground along the NW flank. The latter continues to expand, and is now 3 times the size it was some 15 months ago.
But perhaps even more exciting is that the NW flank remains open, both to the North (the last hole drilled yielded 30g/t over 1m), and to the west and at depth (with reconnaissance hole RC303 returning our first high-grades at depth, namely 36 g/t at 120m downhole).
We are very fortunate that Aurora Tank combines high-grade intersections that are close to surface, with excellent metallurgy, making Aurora Tank potentially amenable to low-cost low capex open-pittable heap leach methods, which are our clear focus.
Aurora Tank keeps on growing thanks to the efforts of our exploration team: on behalf of all shareholders, may I extend our thanks to them. Our underlying fundamentals are very attractive, our cash position is extremely strong, and so too the potential rewards to our shareholders. ”

What’s Next ?
Aurora Tank Gold and Gawler Craton Gold
• RC and Diamond drilling
Further RC and Diamond drilling is being planned. Marmota has been drilling local water bores at Aurora Tank to supply both intended Diamond drilling, and to supply a potential heap leach operation, and to support the camp. [ ASX:MEU 17 Dec 2020 ]
- Marmota is exploring options to bring Aurora Tank into production by low-cost low-capex openpittable mining, including heap leach methods , following very successful column leach testing results. [ ASX:MEU 10 Oct 2019, 25 Nov 2020 ]
• The Company has been adopting a ‘ work in parallel ’ methodology, which allows us to advance both the exploration side and production pathway simultaneously. It means the Company is typically working at full capacity, even in periods that are traditionally quiet for the industry. In December, Marmota carried out the first ecological surveys (fauna and flora) and hydrology work (including to supply water at Aurora Tank) that are also necessary components to seeking a Mining Lease. The subsequent January 2021 period has been our busiest January ever, with two teams active in a very substantial sampling program at both Aurora Tank and surrounding tenements, in exploration work that is being jointly funded by the SA Government under a $225,000 grant awarded to Marmota under the Accelerated Discovery Initiative [ ASX:MEU 24 June 2020 ]. Further detail will be provided when Stage 1 is complete, and the teams have returned collected samples to Adelaide.
