Cautionary Statement

The Scoping Study referred to in this report is based on low-level technical and economic assessments, and is insufficient to support estimation of Ore Reserves or to provide

assurance of an economic development case at this stage, or to provide certainty that the conclusions of the Scoping Study will be realised.

Competent Person Statement

Highlights - Copi North HMS Deposit Scoping Study

Shallow, (6-25m cover), free-digging, unconsolidated sands/silts, low clay

Base Case: Waste:Ore ratio 3.6:1, mining an average grade of 9% HMS

1.4Mtpa throughput with an initial 5 year life

Production: ~100,000tpa HM concentrate (zircon-rutile-(leucoxene & ilmenite))

to undiscounted net cash flow (EBITDA)

Copi North is the first cab off the

rank for a ‘pipeline’ of high-grade

shallow HMS deposits which could

add many years of cash flow.

Improvements to OPEX through lower fuel prices?

Plant mobility and ‘pipeline’ mining of deposits favours off-grid power

The Scoping Study used a fuel price of A$1.15 per litre and this may

have been conservative and does not include the current Mining rebate

of 38 cents per litre.

Using a lower fuel price could trim off considerable OPEX and as a rule

of thumb … for each 15 cent of lower fuel price;

overburden removal costs will drop by about 6 cents per tonne

ore mining costs will drop about 3 cents per tonne

Drilling to extend resource recently completed

Drilling has extended the

Copi North strand ~3km

further west where

mineralisation becomes

shallow (4-5m of cover) but

grade is slightly lower (visibly

2-5% HM) with similar width

of strand (200-220m).

Abundant groundwater for processing

Government water bores, located

about 2.5km south of Copi North

could supply process water.

Three bores have strong and

sustained water flows on separate

saline aquifers (16-32m, 226-231m

and 411-423m).

Baseline environmental data collection commenced

The Copi North environmental

recording station is fully operational

and providing important baseline

data.

Page 20: Ian Pringle - Broken Hill Prospecting - An update on the Copi North and Magic HMS Deposits

Flora/fauna/archeology surveys have commenced

“No Aboriginal cultural heritage places were previously

known from the study area and none have been

encountered during our field inspections to date”

Dr Matt Cupper (Landskape)

7 biometric vegetation types

1 threatened ecological community was found in

restricted areas marginal to HMS resource

1 threatened flora species was recorded outside

the study area

Three general fauna habitats recognised

Field surveys identified 47 fauna species

Page 21: Ian Pringle - Broken Hill Prospecting - An update on the Copi North and Magic HMS Deposits

Mined head grade assumed 5.5% HM (from Inf Res 15Mt @ 3.7% HM)

Assumed Waste:Ore ratio of 3.0 : 1.0

Pit optimisation has not been run

Assumed same process recoveries for Magic as Copi North

Transport costs to Broken Hill and return (lower) but assumed same

Include A$5 million relocation costs

Adding 2 years of Magic onto the Base Case of Copi North will …..

…. increase undiscounted cash flow by A$11.2m and the DCF by A$6.2m

“Cash flow is very impressive if several years of production are added

from Copi North (west extension) to extend mine life to 7-8 years….

…and then if the plant is relocated to Magic for another 2+ years the

project fundamentals seem outstanding” (John Wyche, AMDAD)

Magic HMS Deposit may give additional value
