==> picture [153 x 64] intentionally omitted <==
Under the terms of the proposed acquisition, the CBNP will be acquired by ESR subject to the satisfaction of certain conditions precedent which are set out on page 9 of this announcement.
The CBLC is a 75km2 layered mafic igneous complex, which hosts several occurrences of nickel and copper sulphides. The most significant occurrence discovered to date is at the Carr Boyd Rocks mine, where mineralisation is hosted by bronzitite breccias (pyroxenites) emplaced within the gabbroic sequence of the Complex.
The project is conveniently located, just 80km north north-east of Kalgoorlie. An all-weather haul road accessible by Apollo under a granted miscellaneous license connects the Project to the Goldfields Highway via Scotia.

CARR BOYD HISTORY
The Carr Boyd Rocks deposit was discovered by Great Boulder Mines in a joint venture (JV) with North Kalgurli Ltd in 1968. The deposit was mined between 1972 and 1975, during which time the JV explored for additional breccia pipe occurrences near the mine.
WMC acquired Great Boulder Mines Ltd in 1975, briefly reopening the mine in 1977 before closing it permanently shortly thereafter due to a collapse in the nickel price. The mine had produced 210,000t at 1.44% Ni and 0.46% Cu before its closure.
Between 1968 and 2016 several companies have controlled the ground over the CBLC, including:
-
Pacminex Pty Ltd, which discovered sulphide occurrences such as Tregurtha, West Tregurtha and Gossan Hill;
-
Defiance Mining, which explored for PGE deposits and studied re-opening the mine;
-
Titan Resources, which explored the basal contact of the CBLC and continued economic evaluations at the mine;
-
Yilgarn Mining, which entered a JV with Titan Resources in 2005;
-
Consolidated Minerals, which acquired Titan Resources in 2007, and
-
Salt Lake Mining, which purchased the asset in 2013.
-
Apollo purchased the asset from Salt Lake Mining in early 2016.

Figure 3. Map showing Carr Boyd exploration targets and prospects over interpreted bedrock geology.
The very encouraging observation of the historic exploration is that very few drillholes penetrated the basal contact. For example, between Schmidt, Tregurtha, and West Tregurtha (see Figure 3 above), of the 204 historic holes drilled only 6 are interpreted to intersect the basal contact, and no holes intersect the basal contact below 150m vertical from surface. This is despite large concentrations of cloud and disseminated sulphides in the immediate hangingwall, within CBLC pyroxenites and peridotites, particularly at Tregurtha.

WORK COMPLETED BY APOLLO
Diamond hole CBD022 was re-entered and HPDHTEM surveyed as part of a due diligence process during the acquisition of the CBNP by Apollo Phoenix. The hole was successfully surveyed to 1450m depth. The known remnant mineralisation was clearly visible, indicating the technique should be effective for locating massive nickel sulphides in the CBLC.
CBD022 is a 1461m hole drilled by Yilgarn Mining in 2005, targeting depth extension to the mineralisation at the Carr Boyd Rocks mine and to test the basal contact. It is a source of useful information about the CBLC. The core is stored in the DMP core library in Kalgoorlie. The hole was re-logged geologically by Apollo in consultation with expert consultant, Dr Martin Gole.
Sulphur saturation and the high prospectivity of CBLC were confirmed. Comments (modified) from Dr Gole included:
1. “The CBLC consists of two main components: a southern lower ultramafic zone composed of a wide variety of pyroxene and olivine cumulates (pyroxenite and peridotite) and a northern upper mafic zone composed dominantly of gabbro. This latter zone is composed of both plagioclase-pyroxene cumulates and, higher in the Complex, non-cumulate gabbros. The complex-scale and small scale (~1-2 m) fractionation indicators show a consistent south to north younging direction (in agreement with all recent reports).
2. There is abundant evidence for numerous injections of new magma during the build-up of the layered Complex. In the middle section of the Complex this is commonly marked by pyroxenite layers with sharp bottom contacts overlying gabbro layers.
4
==> picture [153 x 64] intentionally omitted <==
3. The Complex contains widespread magmatic sulphides both in the area of the Carr Boyd mine (discussed further below) as well as disseminated sulphides most commonly associated with pyroxenite cumulates but also olivine cumulates and gabbroic rocks. These occur over a significant stratigraphic thickness in the lower part of the intrusion (at least Tregurtha to Carr Boyd mine). Such occurrences very clearly indicate that the parent magma of the Intrusion was S-saturated and carrying sulphide into the intrusion over a significant period of the evolution of the Complex.
4. The Complex is thus considered highly prospective for the discovery of additional massive sulphides along or near the basal contact, within a possible feeder dyke within the footwall and near-footwall country rock sequence, and as re-mobilised sulphides injected into the basal footwall country rock sequence during post-intrusion regional-scale deformation. The extent of the basal contact is not currently known with certainty but is likely to be along the southern and southwestern margin and possibly an unknown distance north along the western contact. Whether the original basal contact is preserved is also not known.
5. It appears to me, admittedly based on incomplete knowledge, that much historic Ni sulphide exploration at Carr Boyd was not directed towards the area of greatest potential for massive sulphide mineralization; that is toward the basal contact and the immediate footwall sequence. Thus, despite a long history of exploration within the Complex there is significant remaining potential for further Ni sulphide discoveries.”
Historic detailed gravity and magnetic datasets were subsequently re-compiled by Apollo, re-processed and 3D inversion modelled. Several coincident gravity and magnetic anomalies were generated by this work.
A deep coincident gravity and magnetic target was identified at Tregurtha South, within 500m of significant occurrences of cloud and disseminated sulphides at Tregurtha and Tregurtha West. The relatively deep target occurs in an area virtually untested by historic drilling. This target was selected for testing by a single co-founded drillhole under the DMIRS Exploration Incentive Scheme.
A HPMLTEM survey was completed over the southern and south-western portion of the CBLC. This survey detected a very strong EM conductor at Tregurtha South, henceforth named Sir William Wallace. SWW is located almost directly above the co-funded drill target. The EM conductor source is interpreted to be located mostly, if not wholly, inside the CBLC. It is the target of the first drillhole, NCB0001, which has commenced.
Geochemical datasets were reprocessed, new structural measurements were collected, and these combined with all other datasets and historic reports to create a 3D structural and basal contact model to aid with exploration and drill targeting.
SIR WILLIAM WALLACE HPMLTEM TARGET
As briefly outlined earlier, Apollo conducted a HPMLTEM survey over the southern and south-western boundary of the CBLC. This survey was designed to identify large strong conductors indicative of massive sulphide development that could not be detected by the older, less powerful and less sophisticated technology used to conduct previous surveys.
The last concerted effort of ground electromagnetics was conducted by Defiance Mining between 1997 and 1998. Defiance conducted a series of moving loop SIROTEM surveys covering most of the ultramafic part of the CBLC. The power levels and configuration of this survey indicate that it would not have penetrated more than 150m below surface. The equipment available today can penetrate to at least 500m below surface for a large conductive body in resistive terrain.
Defiance identified a number of EM conductors during the 1997/98 surveys, but left several untested and did not make a major discovery. One other very important advance from 1997 to the present has been the introduction of powerful computers and graphics. This has resulted in the ability to produce 3D target models with high precision levels. The coarseness of the technology available in 1997 meant that conductors could often be missed, even when targeted by drilling.

==> picture [153 x 64] intentionally omitted <==
The HPMLTEM survey conducted by Apollo identified the Sir William Wallace conductor. The conductor model is approximately 400m x 125m areal size, dipping at approximately 50-60 degrees north-east and plunging shallowly south-east. The depth to the top at its shallowest part is approximately 100m to 125m vertical from surface. The target depth in drillhole NCB0001 is between 150m and 160m downhole. The hole is collared at 366578mE, 6669672mN, and 415mRL on GDA94 Zone51. The hole is drilling at -60 towards 200 grid azimuth.
The target has a conductance of 8000-10000 Siemens, which is consistent with the presence of well-developed sulphides. Modelling was very robust, so the target depth and geometry are well refined.
Electromagnetic modelling currently does not discount the presence of deeper conductors, electrically disconnected from and/or obscured by this source. DHEM will be conducted on NCB0001 and all subsequent holes to determine if this is the case.

SOUTH TREGURTHA COFUNDED TARGET
Apollo received a large archive of high resolution aeromagnetic and ground gravity datasets as part of the CBNP acquisition. Previous operators had collected gravity data on a 100m by 100m grid and aeromagnetic data on 50m line spacing over most of the Western lobe of the CBLC. These datasets had been processed and interpreted in 2D, but not before in 3D.
Apollo compiled these datasets, reprocessed them and constructed 3D inversion models from them. This identified a series of coincident gravity and magnetic anomalies. The one at South Tregurtha was identified as very high priority due to:
-
Proximity to the basal contact;
-
Proximity to cloud and disseminated sulphide mineralisation at Tregurtha and West Tregurtha;
-
Located in a window of limited historic drill testing; and
-
• Strong geological, structural, and geochemical support.
Therefore, this target was selected for drill testing by a single deep drillhole with support from a co-funding application.
Following drilling, the hole will be surveyed by HPDHTEM, gyroscope, magnetic susceptibility and 3 component magnetics to ensure the maximum amount of data is generated by the hole. This will aim to de-risk follow-up drilling by providing “hard targets” based on physical properties.
The hole will also be logged by a structural geology consultant, to refine the structural architecture of the CBLC, maximising cost effectiveness of follow-up exploration programs.

| •The geology of the Carr Boyd area is dominated by the Carr Boyd layered mafic-ultramafic | ||

| The intrusion has been interpreted to have been tilted to the east with the geometry of the | |||
| intrusive further complicated by regional deformation and folding. The sequence has been | |||

| •Several distinctive styles of Ni and Ni-Cu mineralisation have been identified within the CBLC. | |||
| At the Carr Boyd Rocks Nickel Mine Ni-Cu mineralisation is hosted within several 20 - 60m | |||
| diameter brecciated pipe-like bodies that appear to be discordant to the magmatic stratigraphy. | |||
| Mineralisation is hosted by a matrix of sulphides (pyrrhotite, pentlandite, pyrite and chalcopyrite) | |||

| •Stratiform Ni-Cu-PGE mineralisation has been identified at several different stratigraphic levels | |||
| within the layered magmatic complex. Low grade stratiform disseminated Ni-Cu-PGE sulphides | |||
| have been identified at several locations within the basal parts of the complex and at shallower | |||
| stratigraphic levels of the complex. The presence of Ni-Cu-PGE mineralisation within multiple | |||
