Introduction
Macro View - : HMP Reconciliation
What happened between May 2011 and now?
May – Forecasts and models indicate positive cash flow
June – Two adverse and unforeseeable technical issues arose:
-
Unexpected high water inflow in mine development (rectified by increasing pump out rate)
-
Unexpected and persistent grade short-fall (addressed by completion of infill grade control drilling)
Overall production impact:
-
Mine development further in arrears by 1 month.
-
Mill campaign currently 1 month behind (delayed receipt of $8M to $10M).
-
Lower revenue ($2M to $4M) – reduced grades causing lower concentrate production.
-
Higher cost ($2M to $3M) – water management and ground support
-
Mismatch between timing of revenue and costs
-
Sales of concentrate occur every second month
-
Mining costs incurred monthly
Overall cash shortfall of $12 to $17M in July 2011 as compared to forecast in May 2011

Hellyer Mine Project Mine Plan – revised with detailed drilling and recent water issues
June – Two adverse and unforeseeable technical issues arose:
-
Unexpected high water inflow in mine development (rectified by increasing pump out rate)
-
Unexpected and persistent grade short-fall (addressed by completion of infill grade control drilling)
Revised Mine plan - Fundamental Changes
-
Focus on high-grade massive sulphide ore – more detailed data 2 . Upgraded dewatering infrastructure
-
Mine development now almost completed
-
Increased operating cost assumptions
5. Reduced production rate forecasts
Robust, lower risk plan.
Recognises the issues arising in the past and leaves scope for upside.

Ramifications of Fossey,Fossey-East & MacKay discoveries
New Lesson -expanded potential
-
Even after many years of exploration - great potential for another discovery on the Hellyer mine lease
-
Hellyer – Que River – Mt Charter large mineralised zone with strong alteration, Bass has developed a methodology for navigating / vectoring within the alteration
-
Mineralisation within the Footwall – whole new area to test eg Mackay & Fossey East
Outlook
-
Test for extensions
-
Infill on existing resource
-
Increase resources close to existing mine infrastructure

Bass Scoping Study (2010)
-
Significant historic (1990’s) testwork on refractory gold recovery – but at $ 300- $ 500/oz Au p rice.
-
BSM completed scoping study on historic results and modern cost estimates
-
Highlighted potential for project producing 80 to 130koz Au(eq)/year for 6-8 years at $550 to $740/oz Au(eq*) operating cost for Pressure oxidation and Albion process routes.
-
Capital Cost estimates were $116M to $143M (POx and Albion respectively)
-
Feasibility Study (in progress)
-
Preliminar results: y
-
Confirm and enhance Albion Au and Ag recoveries
-
Confirm & enhance Pox Au recoveries with Ag results pending.

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.

Attachment 2: Conceptual Mining Study-Fossey East
Fossey East Mining Concept Study Parameters
-
The Fossey East concept study treats the new ore body as an extension of the Fossey ore body. To access the FE ore body the study assumes extending the current Fossey decline (post the exploration drive) and hence the capital development required to open up the Fossey East resource is minimal. Mining costs have been reduced by 20% compared to the current Fossey costs, due to Fossey East h av ng a sma i ll er oo pr n requ r ng ess eve opmen an f t i t i i l d l t d th e ma or j it y o f th e m n ng n ras ruc ure i i i f t t already being in place. Milling costs and concentrate sales terms are a mirror of the existing Fossey ore terms.
-
Metal prices:
-
Zinc – US$2 , 293/t
-
– Lead – US$2,577/t
-
– Copper – US$9,031/t
-
Silver – US$37/oz
-
G o ld – US$1 , 538/ oz
-
FX = AUD:USD 1.06
-
Other Assumptions used:
-
The NSR values both cases is based on current Fossey terms.
-
The mining costs are lower for Fossey East (opex) as the foot print for the mine is smaller than for Fossey, and back fill requirements (CAF fill reduced).
-
Capital costs decline, FAR and RAR are based on costs we are incurring currently
-
Fossey East capital includes $1M for dewatering Hellyer
-
The models give a Net return of $17.5M and $24.5M for the 2 options considered.
