CBNP SUMMARY

The focus of fieldwork during the quarter was at the CBNP. Three diamond holes were completed in the Sir William Wallace and Tregurtha South areas and preparations were made to extend a moving loop high power electromagnetic survey further to the north over the prospective basal contact position of the CBLC. This work is expected to commence in the March 2018 quarter (see EM Surveying later in this report).

SIR WILLIAM WALLACE HPMLTEM TARGET

Sir William Wallace was targeted by drillhole NCB0001. The hole intersected the basal contact at approximately 122.6m downhole. Several zones of nickel and copper sulphides were intersected, including within the CBLC, on the basal contact, and in the immediate footwall. This has provided further vindication of the target model being pursued at Sir William Wallace, even though the EM conductor source was attributed to a sulphide black shale horizon located outside of the intrusion further downhole. The zones of nickel and copper sulphides identified were cut and sampled, confirming the presence of nickel-copper sulphides (see Table 1: Assay results NBC0001).

The unmineralised sections of the ultramafic sequence in NCB0001 appear to be nickel depleted, with HXRF readings typically significantly lower than would be expected, particularly in the peridotites. Nickel depletion of the ultramafics silicate minerals, particularly olivine’s, is a key indicator for the formation of large and super-large nickel deposits at the base of layered mafic intrusions.

The basal contact was intersected significantly shallower than previously anticipated in NCB0001. As a result a second hole, NCB0002, was drilled up dip of NCB0001 to get a better understanding of the basal contact geometry. This subsequently allowed for refined positioning of the co-funded drill hole to screen a larger area of the contact.

Figure 2. Photograph of a bleb of semi massive nickel sulphide at approximately 125.4m downhole in NCB0001. This sulphide is interpreted to be remobilised into the pillow margins of the footwall basalt sequence from the CBLC.

NCB0002 was successfully completed to a final depth of 146.6m. It was designed to test the basal contact position 40m up dip of the NCB0001 pierce point and to determine the basal contact orientation. This would assist with the positioning of the co-funded deep platform hole (NBC0003), which targeted a gravity-magnetic feature within the CLBC. NCB0002 intersected the basal contact zone at approximately 107m downhole, confirming the position and orientation of the basal contact, which was intersected within a few metres of the projected position based on structural interpretations of NCB0001.

Sulphide mineralisation was intersected by NCB0002, though it was less abundant than observed in NCB0001 deeper down the contact. This suggests that the sulphide mineralisation could be increasing with depth at Sir William Wallace. A follow-up hole testing the basal contact at a deeper level is planned to commence shortly. This will be an EM platform hole, drilled at a low angle to the basal contact. The hole will be drilled approximately 140m east of NCB0001 and NCB0002, targeting a change in strike in the basal contact which is coincident with a subtle magnetic anomaly.

If nickel-copper mineralisation is developed deeper below surface in the Sir William Wallace area, it would be in an area below the black shale horizon detected by surface EM and targeted by NCB0001. If this was the case it would be virtually invisible to surface EM techniques, as the black shale would effectively obscure conductors located at a deeper level.

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 and constructed 3D inversion models from them. This identified a series of coincident gravity and magnetic anomalies (targets). The target 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 (NCB0003) with support from a co-funding grant of $120,000.

The hole was drilled to a depth of 827.4m, before being stopped in late December 2017 to allow enough time to complete the co-funding interim report before the December 31 deadline. Failure to complete the drilling and submit the report before this date would result in forfeiture of the co-funding grant. The hole will be continued in the New Year, aiming to penetrate to at least 1000m depth and intersect the basal contact of the CBLC.

The hole was surveyed by HPDHTEM, gyroscope, magnetic susceptibility and gamma density to ensure the maximum amount of data was generated. This aimed to de-risk potential follow-up drilling by providing “hard targets” based on physical properties. The Company is currently interrogating these new datasets.

EM SURVEYING

The current moving loop HPEM* (Phase I) survey extends approximately 1.5km north, 1.7km west and 3.3km east of Sir William Wallace. The basal ultramafic sequence is interpreted to extend northward along the western contact of the CBLC to at least 1.4km north of the Carr Boyd Rocks mine, but more likely to 3.6km north of the mine.

A Phase II moving loop HPEM survey is proposed to extend the coverage 3.3km further north from the current Phase I survey, screening the interpreted basal contact position and immediate footwall sequence to 1.4km north of the Carr Boyd Rocks Mine. There are several historic high priority exploration targets and prospects in this area based on surface geochemistry, downhole geochemistry, aeromagnetics, ground gravity and interpreted geology datasets. HPEM will determine if significant conductors indicative of the presence of well-developed sulphides are associated with any of the exploration targets.

ABOUT THE PROJECT AND THE CBLC

The CBLC is a 75km[2] 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 CBLC is in a Tier 1 jurisdiction approximately 80km north north-east of Kalgoorlie Western Australia. An all-weather haul road accessible by Apollo under a granted miscellaneous license connects the Project to the Goldfields Highway via Scotia.

A “Voisey Bay” style model has not been adequately explored within the CBLC. This represents a compelling exploration target opportunity which the Company will continue to aggressively pursue.

WIDGIEMOOLTHA ENERGY METALS PROJECT

The Company finalised the WA Nickel Pty Ltd (WAN) acquisition during the quarter, with shareholder approval received and all relevant due payments settled post quarter end. This gave ESR 100% interest in nickel rights at the Spargoville Project and 100% ownership of all metals on M15/87 (Munda).

The new projects were added to the Mount Edwards Lithium Project (MELP), with the consolidated project now referred to as the Widgiemooltha Energy Metals Project (WEMP). The WEMP hosts several high priority nickel, gold and lithium targets, which the Company intends to further develop in the coming

year. This includes gold and nickel opportunities at Munda, nickel opportunities at Spargoville, and lithium opportunities at Atomic Three and Inco Boundary.

MUNDA GOLD

The Munda project hosts a JORC Code 2012 reported Inferred gold Mineral Resource estimate of 511,000t at 2.82g/t Au (Table 2).* Within this Mineral Resource several very high-grade zones occur, which are interpreted to be formed where sub vertical NNW trending structures intersect a sheared basal contact between an ultramafic hangingwall and metabasaltic footwall.

This is interpreted to result in very high-grade plunging shoots within a lower grade envelope of gold mineralisation. These high-grade shoots will be targeted by drilling and if the interpretation is confirmed, they will be evaluated beginning with a Scoping Study to determine if they can be economically extracted.

An open pit mining operation was commenced in 1999 by Resolute Mining Limited, but was shut in 2000 due to a dramatic fall in the gold price at the time to sub A$400/oz Au. With gold now holding above A$1,500/oz, there is considerable scope to complete the mining of the remaining Mineral Resource.

A POW was submitted and approved for the drilling of two holes, targeting the high-grade gold zone intersected by MND1406. The Company intends to drill these holes as soon as possible.

MUNDA NICKEL

Closely associated with, but separated from the gold mineralisation at Munda, is a significant deposit of nickel sulphide. A JORC Code 2012 reported Inferred Mineral resource of 240,000t at 2.36% Ni has been estimated for the deposit.*

The nickel mineralisation is interpreted to be a “Kambalda Style” nickel sulphide occurrence, located at the basal contact between a high MgO komatiitic ultramafic unit and a footwall basalt. Mineralisation is concentrated in thermal and structural embayments in the basal contact and in “footwall carrots” in the basalt.

Significant potential exists for further nickel sulphide mineralisation down plunge of the Munda Mineral Resource. Several DHTEM conductors were identified down plunge to the nickel mineralisation by Titan Resources during exploration programs conducted up to 2007, but these are yet to be followed up by drilling. The project was abandoned at the time due to a fall in the nickel price.

There are also two greenfields EM conductor targets, M15/87-C1 and M1587-C4, located north west of Munda within M15/87. These conductors were identified by Consolidated Minerals during MLTEM surveys completed in 2010. During the quarter, a follow-up soil sampling program was completed over this area.

SPARGOVILLE NICKEL

The Spargoville area hosts several nickel mines which have been exploited to varying degrees in the past, including 1A (nickel), 5A (nickel), 5B (nickel and gold), and 5D (nickel). Global and remnant Mineral Resources have been published by previous operators for each of these occurrences, but they are not up-dated to JORC Code 2012 reporting compliance, so cannot be quoted at this stage. It is envisaged that only a small amount of new data will need to be collected, if any, to advance these projects to JORC Code 2012 reporting standard. The Company intends to add them to the Mineral Resource inventory and to conduct economic evaluations.

Now that the WAN transaction has been finalised, the Company can take possession of the historic drill cores and digital databases for Spargoville and progress 1A, 5A, 5B, and 5D to JORC 2012 reporting standard.

1A

The 1A project was mined between 1990 and 1992. It produced 112,800t @ 3.8% Ni (4,286t Ni metal) before its closure in 1992. Three 25m spaced underground levels were mined to a vertical depth of 175m below surface.

Breakaway Resources (BRW) conducted drilling programs through 2007 and 2008 confirming depth continuation of high grade nickel sulphide mineralisation, including intercepts of 5.60m at 4.27% Ni, 7.29m at 6.94% Ni, 8.35m at 3.49% Ni, 1.84m at 4.95% Ni.[*] This extended the mineralisation up to 200 metres down-plunge of the mine workings on three separate surfaces.

Optiro completed a fully depleted Inferred Mineral Resource estimate on the project in 2009. This Mineral Resource estimate was completed to JORC 2004 reporting standard, terminating at 280m below surface. There is significant potential to upgrade this to JORC Code 2012 Mineral Resource reporting standard and to extend it further down plunge.

Down plunge extensions could be achieved using targeted drilling programs guided by modern high power DHTEM surveying. The DHTEM technology available today was not available to previous operators.

5A

Thick high-grade nickel intercepts have been returned from drilling by previous operators beneath an historic oxide gold open pit at 5A. These intercepts represent a compelling target for generating a JORC Code 2012 Mineral Resource estimation and economic evaluations.

The high-grade nickel mineralisation appears to be open at depth. This represents significant exploration upside at the project.

Scoping Studies completed by previous operators have determined that high metallurgical recoveries are achievable on the mineralisation. This would be advantageous should an economic mining operation be possible on the project.

A strong downhole EM conductor has been identified within and below currently defined mineralisation. This conductor represents a compelling drill target for ESR.

5D (Andrews)

The 5D project was mined via the Andrews Shaft. The mine was active between 1975 and 1979 when it was developed to 250m below surface. There are no production figures available on open file for the project.

A fully depleted remnant Mineral Resource was estimated by Geostat in 2004 to JORC Code 1999 reporting standard. This Mineral Resource estimate only included material between levels 2 and 11 of the mine, excluding lateral and depth extensions. Drilling completed by BRW in 2007 and 2008 confirmed the mineralisation extends at depth beyond the 11 level, with DHTEM modelling indicating that the mineralisation extends further to the north.

5B

The 5B project was mined between 1975 and 1982, and again between 1992 and 1993 via an open pit. Approximately 14,000t of nickel was produced between the two mining campaigns.

A decline was established post mining to allow drilling of the nickel and gold mineralisation from underground. The details of this operation are not available on open file.

A drilling program completed by Minotaur in 2014 confirmed historic nickel intercepts. Results included:

  • 15m @ 1.41% Ni in hole SPRC001*

  • 16m @ 0.98% Ni in hole SPRC002*

  • 16m @ 1.82% Ni (including 6m @ 3.60% Ni) in hole SPRC003*

  • 24m @ 1.53% Ni (including 6m @ 3.08% Ni) in hole SPRC005*

Mineral Resource estimates were completed on 5B by previous operators, but they were not completed to JORC Code 2012 reporting standards and therefore cannot be stated. ESR believes there is strong potential to upgrade the project to a JORC Code 2012 Mineral Resource and extend mineralisation with further drilling down plunge.

These existing mineralised occurrences are located on a significant landholding of exploration tenure, providing potential exploration upside to ESR, particularly given the recent advances in electrical geophysical technology and power levels since previous operators were active on the projects.

ESR has already identified four electromagnetic conductors in the historic data. One of which, M15/96C1, straddles the boundary between ESRs existing tenement M15/96 and the newly acquired tenement M15/395. The conductor is located between 5A and 5D and appears to be located on the same basal contact. It has a conductance of 6000 siemens and has good support from aeromagnetic data. This target will be assessed against geological and geochemical datasets before a decision to drill.

LITHIUM PROGRAMS

Approximately 12 – 15 RC holes are proposed for Atomic Three, with planned depths between 60m and 72m. Holes will be drilled at -60 towards 80 in a “top to tail” formation, roughly perpendicular to the stratigraphy. This will ensure the entire stratigraphic width of the anomalous pegmatites is sampled. Drilling will target directly beneath the highest-grade rock chip results, and the where pegmatites have the widest surface expressions. Three holes are also planned for Inco Boundary.

POW approvals remain in place for the follow-up drilling programs at Atomic Three and Inco Boundary. The Company intends to complete them in the first half of 2018.

A soil sampling program was completed over the Atomic Three prospect area during the previous quarter, which includes Bravo Charlie. 458 samples were collected on a 200m by 50m grid pattern. The aim of the soil sampling program was to determine if soil sampling could be an effective technique for identifying blind lithium bearing pegmatites with no visible surface expression, and if so, determine if there are any such pegmatites in the Atomic Three area. At this stage it is unclear if soil sampling is an effective technique for identifying blind pegmatites.

WMC acquired Great Boulder Mines Ltd in 1975, briefly reopening the mine in 1977 before
Criteria JORC Code explanation Commentary
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.
From 1968 Pacminex Pty Ltd held most of the ground over the CBLC outside of the immediate
mine area. Between 1968 and 1971 they conducted extensive exploration programs searching
for large basal contact and/or stratabound Ni-Cu deposits. It was during this time that most of
the disseminated and cloud sulphide occurrences such as those at Tregurtha, West Tregurtha
and Gossan Hill were discovered.
Defiance Mining acquired the regional tenements from Pacminex in 1987 and focused on
exploration for PGE deposits between 1987 and 1990. In 1990 Defiance purchased the Carr
Boyd Rocks mine from WMC and switched focus to the mine area between 1990 and 2001,
leaving many PGE targets untested.
From 1990 Defiance dewatered the mine to conduct testwork and feasibility studies on the
remnant mineralisation. Metallurgical testwork, mineral resource estimations and scoping
studies were completed. Around 1996 the focus shifted again to regional exploration for large
tonnage basal contact deposits.
In 2001 Titan Resources Ltd (Titan) acquired the project and recommenced economic
evaluations of the remnant material at Carr Boyd Rocks before embarking on another regional
exploration program focusing on the basal contact. An aeromagnetic survey, airborne EM
reprocessing, and several programs of RAB and RC drilling were completed.
From 2005 Yilgarn Mining entered a JV with Titan and continued with some regional
exploration, but focused most attention in and around the Carr Boyd Rocks mine.
In 2007 Titan was acquired by Consolidated Minerals Ltd (Consmin). Consmin conducted IP

surveys and detailed gravity surveys, but did not drill any targets before selling the project to
Salt Lake Mining (SLM) in 2013. SLM completed limited drilling to meet expenditure
commitments, before selling the project to Apollo Phoenix Resources in 2016.
Geology Deposit type, geological setting and style of

mineralisation. deformed and folded mafic, ultramafic rocks and volcanic sediments intruded by granitoids which
is referred to as the Norseman-Wiluna Belt. The belt has been divided into several geological
distinct terranes, with the project area lying at the northern end of the Gindalbie terrane (Swager,
1996).
The geology of the Carr Boyd area is dominated by the Carr Boyd layered mafic-ultramafic
intrusive complex (CBLC). This layered intrusive covers an area of 17 km by 7 km and has
intruded into an Achaean Greenstone/Granite succession. The CBLC is comprised of a basal
sequence of dunites, which are overlain by peridotites / pyroxenites and above that by gabbros.
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
metamorphosed to upper greenschist to lower amphibolite facies.
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)
within brecciated Bronzite and altered country rock clasts.
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
Criteria JORC Code explanation Commentary
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
stratigraphic positions and of several unique styles of mineralisation highlights the potential of
the CBLC for hosting a substantial Ni-Cu deposit.
