Burracoppin Gold Project Overview

The Burracoppin Gold Project comprises an exploration licence E 70/5049 with an area is 6 BL (~17.6km2). The project is located approximately 20km east of Merredin and 15km west of the Edna May Gold Mine in the eastern wheat belt of WA. The project is easily accessible from Merredin using the Great Eastern Highway.

Several gold workings are known within the area including Burgess Find, Easter Gift and Christmas Gift.

The area is underlain by Archaean granite/gneiss greenstone terrane. Greenstones are metamorphosed to amphibolite/granulite grade. Minor banded iron formation outcrops are known, and aplite-pegmatite dykes intrude the amphibolites at the historical Burgess Find gold workings within the tenement. Gold mineralisation occurs within quartz veins and quartz-rich granitic stringers hosted by pelitic sediments, mafic-to-felsic granulites and gabbroic rocks, all of which have a strong tectonic fabric. In general, this foliation strikes in a north-east direction and dips steeply to the west. Quartz veins and pegmatite dykes strike roughly parallel to this foliation and also dip steeply to the west. All of these lithologies are intruded by post-tectonic granites. Laterites that cover the Archaean rock sequence also carries gold mineralisation. The laterite which averages 4m in thickness, consists of loose pisolite with a significant sand matrix component at the surface, grading into a poorly to well cemented nodular laterite layer at roughly 0.5-1m depth.

The Easter Gift workings occur in mafic granulite and metasediments intruded by granitic stringers. The workings occur 25m west of a major granite/gneiss unit. The workings appear to occupy a similar stratigraphic position to that of the Christmas Gift-Benbur North-Benbur workings to the north.

Soil sampling over large areas of the main magnetic feature in the southern part of the tenement, located gold and gold pathfinder anomalies extending beyond the Burgess Find prospects. The Company believes further deeper drilling is warranted to test for plunging shoots associated with these high-grade intersections at Burgess Find and Easter Reward, both at depth and along strike to the north and south along with broader regional exploration including a reinterpretation of geophysical surveys and rock chip sampling.

Mineralisation

Gold mineralisation occurs within quartz veins and quartz-rich granitic stringers hosted by pelitic sediments, mafic-to-felsic granulites and gabbroic rocks, all of which have a strong tectonic fabric. In general, this foliation strikes in a north-east direction and dips steeply to the west. Quartz veins and pegmatite dykes strike roughly parallel to this foliation and also dip steeply to the west. All of these lithologies are intruded by post-tectonic granites.

Laterites that cover the Archaean rock sequence also carries gold mineralisation. The laterite which averages 4m in thickness, consists of loose pisolite with a significant sand matrix component at the surface, grading into a poorly to well cemented nodular laterite layer at roughly 0.5-1m depth. The cemented layer varies in thickness between 0.5-1.5m. Beneath this layer, loose pisolites and/or lateritised regolith nodules with a week vertical structure extend to a depth often exceeding 4m. The basal boundary of this loose lateritised regolith is variable and ranges from ferruginous quartz sands to pallid kaolinitic clays. Gold mineralisation appears to be restricted to the iron-rich laterites and does not persist into the mottled clay zone.

The Easter Gift workings occur in mafic granulite and metasediments intruded by granitic stringers. The workings occur 25m west of a major granite/gneiss unit. The workings appear to occupy a similar stratigraphic position to that of the Christmas Gift-Benbur North-Benbur workings to the north.

Previous Exploration

The area is the site of numerous shallow shafts dug on high-grade gold veins in the 1930s and a small heap leach operation in the early 1990s. The Burgess Find in the east-central portion of the tenement is the site of historical gold mining activity over a period commencing in the early 1900s. Burgess Find mine locality was intensively explored by Miralga Mining NL, Herald Resources Ltd and Valiant Consolidated Ltd in the 1980s (Minedex document MP13863). They developed a small heap leach operation based on a shallow gold-bearing ferruginous pisolite deposit. Presently it consists of a series of four areas of shallow shafts and crosscuts between the shafts. From the north, they are Christmas Gift, North Benbur, Benbur and Easter Gift. Historical literature from the Geological Survey of WA, reports that

the shafts were developed over gold-bearing quartz vein(s) which generally carried over 0.5oz/t gold. Also, there has been a Heap Leach pad developed over an area of gold enriched laterite immediately to the west of the line of shafts, near the Benbur working.

Valiant Consolidated also conducted shallow RC drilling at the Burgess Find area and Eastern Gift.

Cambrian Resources NL explored the wider area in the 1990s. They tested small magnetic targets peripheral to the magnetic complex, with RAB and shallow RC drilling. They also drilled a series of RAB holes across parts of the Burgess magnetic complex, but it is not clear if any of these holes penetrated the regolith and the work is inconclusive.

From 2010 to 2014, Enterprise Metals held the current E70/5049 tenement as part of their Burracoppin project. They completed an airborne magnetic-radiometric survey and some soil and rock chip sampling along with data entry of historical rock chip samples which had prospective results.

Enterprise Metals also completed an RC drilling program designed to test several prominent magnetic features for possible magnetite/hematite and gold/base metal mineralisation. The program consisted of 36 RC holes for a total of 4,048m.

A summary of all drill holes drilled on the tenement is provided in Table 2 of Appendix B of the Independent Geologists Report, while the locations are shown in Figure.

Enterprise Metals also reviewed the historical holes. They identified that Valiant holes BF28-34 were drilled 10m apart on two E-W sections at Eastern Gift (500m south of the main Burgess Find working) to a maximum depth of 20m. Hole BF29 intersected 4m at 11g/t Au from 13m downhole including 1m at 32.4g/t Au from 14m. A single follow-up RC drill hole (RC1 – total depth 45m), testing directly beneath this intersection returned an intercept of 1m at 0.65g/t Au from 33m (Figure 3). Hole BF33 20m on-strike to the south, intersected 2m at 9g/t Au from 18m at the bottom of the hole (Figure 4). No further drill testing of this intersection was undertaken.

Proposed Exploration Program

The exploration program proposed for the Burracoppin Gold Project has two parts. The first part will concentrate on increasing the size of the current, high-grade

mineralised zones at the Burracoppin Gold Project. This will involve twinning historic drill holes and completing new drilling along plunge of the thickest and highest-grade mineralisation found to date. The Company will also drill some additional drill holes along strike of the mineralisation aimed at increasing the overall size of the mineralised zones.

The second part of the exploration program is to complete modern, regional airborne geophysical surveys and reconnaissance exploration at the Burracoppin Gold Project to identify further targets for additional drilling. These regional airborne geophysical surveys will actually be completed first, as they have the potential to add valuable information to help target extensions of the known mineral deposits, as well as discover new mineral deposits under the surface cover.

On completion of the exploration program, the Company proposes to then incorporate these exploration results into a maiden JORC (2012) Mineral Resource estimate that will underpin a scoping study into the viability of mining operations on the Burracoppin Gold Project. The results of this scoping study will then provide guidance for future exploration and development.
