Safety at the mine continues to be an area of focus. The Disabling
Injury rate (DIIR) (the number of lost time injuries expressed
as a rate per 200,000 man hours worked) for the year was 1.66,
compared to the rate of 1.31 the previous year. No fatal accidents
were recorded.
Major safety awareness and action campaigns were implemented
in the second quarter and, at the same time, a safety committee
was established. Special audit teams comprising both Aquarius
Platinum and contractor personnel have been established to
perform safety audits on a regular basis, and to identify
problem areas that can then be jointly addressed.
Cementation Mining, the mining contractor, created several
new positions to improve supervision on a management and supervisory
level. A NOSA (National Occupational Safety Association) audit
of Cementation’s operations resulted in the Central
section achieving a four-star rating, with the East section
achieving five stars. As a result, the mine was able to achieve
a number of safety milestones, including 500,000 fatality-free
shifts. Another milestone was the 1,000 fatality-free production
shifts achievement in a competition run by the Department
of Minerals and Energy.
Minopex, the concentrate plant contractor at Kroondal, was
awarded two NOSA certificates during the year – one
for the best surface plant in the Bushveld region and the
second for being one of the top 20 companies in the Bushveld
region. Minopex retained its NOSA five-star Integrated (platinum)
rating following an audit in February 2004. Minopex has operated
for 16 months without a single lost time injury.
Mining
The year proved to be one during which Kroondal demonstrated
an excellent recovery on the previous year, as the mine was
able to largely overcome the effects of geological disturbances
encountered – such as potholes, faults and pegmatite
intrusions – which had reduced production and had an
impact on costs. Despite the onerous effects of the rand and
additional development, Kroondal was able to maintain a substantial
cash margin of 45%, compared to the 52% achieved the previous
year.
A large part of this success can be attributed to the Beyond
22K cost control efficiency campaign initiated in August 2003.
Beyond 22K is aimed at improving the mine’s control
over its margins and specifically to achieve a 10% increase
in the best-ever historical monthly production – which
translates into output in excess of 22,000 PGM ounces (in
excess of 21,000 ounces per month was achieved in December
and March this year).
The South African Competition’s Commission approved
the PSA with Anglo Platinum in September 2003 and this came
into effect on 1 November 2003. In line with this agreement,
AQP(SA) and Anglo Platinum started sharing revenues, costs
and capital expenditure for Kroondal mine. This has the impact,
however, of halving the production attributable to AQP(SA),
although the production attributable to AQP(SA) is expected
to return to the pre-agreement levels when the expansion is
completed in 2005.
The mine posted record production of 237,626 PGM ounces,
up from 209,061 PGM ounces the year prior, as both production
and cost control improved. In line with the PSA agreement,
attributable PGM production was 160,190 ounces.
Mining operations produced a total 3.19 million ROM tons,
up by 8% from 2.96 million tons; 91% came from underground
and 9% from surface. Of this, 3.14 million tons were processed,
and a 54,179 ton surface stockpile was created by year-end,
as feed material to start the new plant.
The ROM head grade increased 3% to 3.07 g/t owing to changed
drilling patterns and an improvement in overall face availability.
This was negatively affected during the last quarter by the
additional development required to establish the workings for
the increased tonnages required in the future. Recoveries rose
to 76%, as a result of a higher ratio of underground ore to
open pit ore. Continued optimisation of the concentrator cleaner
sections resulted in chrome levels in the concentrate reducing,
and consequently chrome penalties declining to more acceptable
levels.

ROM cash costs increased by 18% to R153/ton, from R130/ton
the previous year. Cash costs per PGM ounce rose by 9.9% to
R2,026 per PGM ounce compared to R1,842 per ounce the previous
year. This increase largely reflects a change in the capex
accounting rules, where development and strike extensions
are now expensed. While this change increases cash costs in
the short term, it provides favourable long-term benefits
as the amortisation charge related to redevelopment and strike
extensions is removed.
Without this impact, the cash cost per PGM ounce would have
increased by only 1.74%, which is a tribute to the production
turnaround at Kroondal.
The mine received a basket price of $599 per PGM ounce,
compared to $509 per PGM ounce the previous year. This was
primarily due to a 30% increase in the platinum price in dollar
terms. Platinum accounts for 60% of Kroondal’s PGM basket.
Progress on the PSA
Following extensive consultation with Interested and Affected
Parties, Phase 3 of the EMPR for the PSA was approved in the
third quarter. As a result construction activity was able
to commence during the year.
Underground development to extend the bord and pillar mining
operations will continue into 2006 until steady-state mining
is reached at 500,000 PGM tons a year. Construction of the
new 250,000-ton per month concentrator plant to process the
additional ore commenced in April 2004, with hot commissioning
scheduled for May 2005, earlier than originally planned.
Underground development of the new sub-decline systems and
the No. 3 decline began in the third quarter and is now well
advanced. A total of 467 metres of down-dip development was
completed by year-end. All development is onreef and the expansion
of mining operations will contribute to increased UG2 ore
production throughout 2005.
AQP(SA) is funding its portion of the capital for the PSA
from current cash flows, the net proceeds on the disposal
of the Waterval Block and an existing debt facility. AQP(SA)’s
share of capital commitments to date is R207 million, with
capital expenditure paid to date of R46 million.
