HIGHLIGHTS
-
EMU completes highly successful maiden drilling programme at its Gnows Nest Project at Yalgoo WA.
-
Two high-grade gold shoots outlined at the Gnows Nest Gold Mine remain open at depth.
-
New zone of high-grade gold mineralisation encountered at the Monte Cristo Prospect.
-
Gradient array IP geophysical survey defines new target areas in close proximity to the Gnows Nest Gold Mine.
-
4,500m follow-up drilling programme testing Gnows Nest Deeps and the Monte Cristo discovery zone to commence once a drill rig is secured.
Emu NL (“EMU” or “the Company”) is pleased to update the market following completion of the maiden 10,932m reverse circulation (RC) drilling program at its Gnows Nest Project near Yalgoo WA. The drilling programme was split between the Gnows Nest Gold Mine and the Monte Cristo Prospect located 3.0km along strike to the NW within the Yalgoo Greenstone Belt.
The drilling programme at Gnows Nest Gold Mine was intentionally focussed on testing extensions to the known high-grade lode system at the historic mine and to better understand the controls of the gold mineralisation. The programme was successful in confirming the geometry of the historic “Main Shaft” gold shoot, and also delineated a south plunging gold shoot which extends from the Mining Lease (M59/739) into the southern Exploration Licence (E59/2315). Both zones of mineralisation are structurally controlled by NNW-trending shears and hosted in quartz veins. Planning for a follow-up RC drilling programme to define the depth extensions to the high-grade shoots at Gnows Nest is well advanced.
The drilling completed at Monte Cristo identified a new gold zone with the potential to significantly increase the Gnows Nest Mineral Resource estimate (MRE). This new target is located adjacent to the historic Monte Cristo mine workings in a similar lithological and structural setting to Gnows Nest (Figure 1 & 2). Follow-up drilling is also planned over the lightly explored host units extending over a ~6 kilometre strike length.

1. Gnows Nest Gold Mine
EMU has successfully completed 88 RC drill holes at the Gnows Nest Gold Mine for a total of 9,166m to an average depth of 104.6 m. Assay results from the step-out RC drilling programme returned further high-grade gold intercepts associated with two plunging shoots of vein-hosted mineralisation hosted in a west-dipping shear zone (Figures 3 and 5). The drilling indicates that the high-grade shoots will continue to depth which will be the subject of a deeper, follow-up RC drilling programme.
The northern, north-plunging shoot is centred on the area of historical underground mining activity at the Gnows Nest Gold Mine, which was developed to a depth of 145m and produced 27,925 oz at a recovered grade of 22 g/t Au, mostly between 1923 – 1941.[1]
The second, south-plunging shoot is located immediately south of the historic mining area and main shaft. Mine workings and exploration shafts in this area are recorded as shallow, extending to depths of approximately 30m.
The gold mineralisation at Gnows Nest is hosted predominantly in a single shear-hosted quartz vein of variable thickness (1 to >6m) which has been variably offset and deformed. En-echelon (repeat) veining observed along the structure is not generally mineralised. The main shear structure runs oblique to the lithology at Gnows Nest, introducing variability along strike, although gold grades have proved to be more consistent within the shoots.

The latest significant intersections (> 1.0 g/t Au) from the Gnows Nest drilling programme, along with the previously reported intersections from 22 February 2021[2] , are summarised in Table 1, with a comprehensive listing of the drill hole specifications provided in Table 3. The drill hole collar plan is shown in Fig 5.
2. Monte Cristo Gold Prospect
EMU completed a total of 17 RC drill holes at Monte Cristo for 1,766m to an average depth of 103.9m. Assay results identified a new zone of high-grade gold mineralisation adjacent to the historic Monte Cristo workings associated with steeply east-dipping quartz veins hosted along a sheared contact between mafic (dolerite) sequences and NW-trending banded iron and chert formations (Figures 4 & 6).
EMU will further test the resource potential of this emerging target at Monte Cristo in a followup RC drilling programme planned in conjunction with the Gnows Nest Deeps programme. In particular, the programme will test the continuity of mineralisation along the sheared contact zone and will extend the search outwards over ~6km strike extent within the project tenements. The prospectivity of this zone is marked by the presence of multiple historical shallow workings but has received minimal exploration attention to date.

The latest significant intersections (>1.0 g/t Au) from the Monte Cristo drilling programme, along with the previously reported intersections from 22 February 2021,[2] are presented in Table 2. A full listing of the drill hole specifications is provided in Table 3, with a detailed collar plan showing the significant intercepts presented in Figure 6.
3. New Regional Targets Identified
EMU completed a gradient array induced polarisation (GAIP) geophysical survey over M59/739 and the SE portion of E59/2315 in February 2021 (Figure 2). This work was conducted by geophysical contractors Zonge Engineering & Research and managed by Perth-based geophysical consultants Resource Potentials.
A total area of 370 hectares (1,850m x 2,000m) was surveyed by GAIP, including the Gnows Nest Gold Mine and the area extending to the eastern tenement boundary. Zonge also completed two dipole-dipole lines to obtain a better understanding of the distribution of chargeability and conductivity through the mine zone with the aim of extrapolating the mineralisation signature.

The geophysical survey delineated multiple target zones for follow-up field work and highlighted a stratigraphic flexure zone south of Monte Cristo for priority evaluation together with several zones adjacent to Gnows Nest Gold Mine. Ongoing regional work will target the +6 km strike length of prospective greenstone stratigraphy in conjunction with the detailed prospect-scale evaluation at Gnows Nest and Monte Cristo (Figure 2).
4. Next steps
EMU has developed a plan for a 4,500m RC drilling programme to test the northern shoot below the historic 5 level at the Gnows Nest Mine to a depth in excess of 250m, and to similar depths at the southern shoot. The programme will also test the resource potential of the emerging target at Monte Cristo. Once a drill rig has been secured, the Company will provide further details on the expected timing of commencement.

out under Company protocols and QAQC procedures as per current industry practice. See further details below. |
|
| In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
RC holes were drilled with a 5.25” face- sampling bit, 1m samples collected through a cyclone and cone splitter, to form a 2-3kg single metre sample and a bulk 25-40kg sample. Samples were collected with a spear to generate 4m composite samples, or variable samples at EOH. The 2-3 kg composite and 1m split samples were dispatched to Nagrom Analytical in Perth. Sample preparation by the laboratory included sample sorting, oven drying, mechanical pulverisation to 95% passing 75 microns. Analytical |

| Yalgoo region, and within the WA | ||
| Yilgarn Craton. The lode is developed | ||

| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: |
|
Refer to collar tables for all reported drill holes in the body of the report. Collar locating and GPS accuracy is included in Section 1. |
o easting and northing of the drill holecollar |
| No material information, results or data have been excluded. |
|
o elevation or RL (Reduced Level – |
|||
| elevation above sea level in metres) of | |||
| the drill hole collar | |||
o dip and azimuth of the hole |
|||
o down hole length and interception |
|||
| depth | |||
o hole length. |
|||
| If the exclusion of this information is | |||
| justified on the basis that the information | |||
| is not Material and this exclusion does | |||
| not detract from the understanding of the | |||
| report, the Competent Person should | |||
| clearly explain why this is the case. | |||
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) |
| Grades are reported as downhole length- weighted averages of laboratory reported grades. No top cuts have been applied to the reporting of the assay results. |
| and cut-off grades are usually Material and should be stated. |
| All higher-grade intervals are included in the reported grade intervals. |
|
| Where aggregate intercepts incorporate short lengths of high grade results and |
| No metal equivalent values are used. | |
| longer lengths of low grade results, the | |||
| procedure used for such aggregation | |||
| should be stated and some typical | |||
| examples of such aggregations should be | |||
| shown in detail. | |||
| The assumptions used for any reporting | |||
| of metal equivalent values should be | |||
| clearly stated. | |||
| Relationship between mineralisation widths and |
