4. Project Development Strategy Growth strategy to generate shareholder value
1. Deliver forecast cash flow from Fossey Mine
-
Complete drill out and feasibility study on Fossey East.
-
Ongoing project/systems/risk review.
2. Assess & potentially develop 1.5M oz gold(eq) resource
-
Gold DFS in progress.
-
Seek technical and or financial partners for development.
3. Increase mine life to underpin long-term cash flow
-
Resources to reserves (Fossey East/Hellyer/Que River).
-
extensional exploration drilling around known resources.

Fossey Zone-an example of new exploration potential
-
Historic drilling focussed on “traditional” VMS target zone.
-
New discoveries lie deeper than this.
-
Opens up significant new targets

25 metres to south – new intercept 1.7 metres at 21.9 % Zn, 14.7 % Pb, 1.0 % Cu, 2.3 g/t Au & 182 g/t Ag Drilling in-progress to the north
New mineralisation in a new geological position
4. Discovery
New prospective geological position – “unconventional VMS target”
==> picture [609 x 228] intentionally omitted <==
==> picture [119 x 97] intentionally omitted <==
-
Highly prospective –under tested.
-
Potential in both the conventional and unconventional VMS stratigraphic position.
• Requires detailed targeted and pattern drilling- utilising new tools in the toolbox for proximity- geology, mineralisation, alteration, trace element geochemistry and geophysics.

7. Value Proposition Value Upside
Broker Valuation (12 September 2011)
-
Helmsec valuation range: from A$105M to A$144M, not including exploration upside or Plant.
-
Equates to A$0.39 to A$0.54 per share on diluted basis post Offer*.
Key Value Drivers:
-
Production - robust and established production, with revenue from base metals (70%) and precious metals (30%): c. $55m in next 18 months.
-
Polymetallic resources – Hellyer, Que River & Fossey East.
-
Gold & Silver Resources – 2 Million Ounces Gold (eq)
-
Exploration upside – highly mineralised area with a track record of discovery and new prospectivity.
-
Processing Plant – modern 1.5mtpa plant.
Strong Exploration Upside Underpinned by Production
- Based only on ordinary shares , does not include C-Note or Options

Notes on Metal Prices and Gold Equivalence
-
Metal prices effecting the gold equivalent calculation are : Gold A$1,430/oz and silver A$35.6/ozs. This generates a Au:Ag ration of 1:40.1. This has been conservatively modified to 1:45 to complete the equivalence calculation based only on contained silver and gold in the respective resources in Table 4 and 5.
-
The grades for the calculation of a Au equivalent grade are from the respective combined resource estimates presented in Tables 4 and 5.
-
No recoveries or other modifying factors have been applied in the calculation. Au is the chosen metal for reporting equivalence as it is potentially the more valuable.
