question on jorc, page-45

An aspect I never thought of but that could be very relevant. Given me something to delve into for a while.

Keep in mind ISR has no heavy mine haulage fleet apart from delivery trucks and drill rigs, maybe a grader or small dozer to clear wellfield pipe routes. Heavy haulage mine fleets use a lot of fuel and this is a huge saving with PEN at Lance.

PEN will probably have their own power plant at Lance but that I can't confirm.

This si a major cost reduction benefit for Lance that will confirm how good Lance is in terms of low cost operation and profitability.

Just to kick off...

ISR Uranium plant Power consumption -
Unit power consumption is about 19 kWh/kgU (16 kWh/kg U3O8) in Australia and around 33 kWh/kgU in Kazakhstan.

As for carbaon credits and convential mining power usage, Lihir is worth a look at. Although this is a gold mine so not apples with apples as far as the process plant is concerned.

Lihir Gold
Power Usage
Geothermal Power Plant - 2008 capacity 56 Megawatts
2008 electrical power requirement 76 Megawatts

Heavy Fuel Oil Consumption
2007 usage ~43,000 tonnes
HFO per megawatt ~0.3 tonnes
Diesel Consumption
2008 usage ~45 million litres

"Geothermal
The Lihir Island project is located in an inactive volcanic caldera,
which retains remnant geothermal energy in the form of steam.
Initially the steam was vented to cool the ore body and enable
safe mining, but since 2003, LGL has harnessed this steam to
generate power for the operation. Current geothermal capacity
at Lihir Island is 56 Megawatts, approximately 75% of the
operation’s power needs.
LGL’s geothermal power plant was the first project in Papua
New Guinea to be registered for carbon credit trading under
the Clean Development Mechanism of the Kyoto Protocol.
LGL generated US$4.5 million in revenue in 2008 by selling
Certified Emission Reductions (CERs) on global markets. The
plant reduces greenhouse gas emissions by approximately
280,000 tonnes per annum, which equates to approximately
four percent of Papua New Guinea’s total C02 emissions."
