In 2022 a disconnect in global energy
markets resulted in higher global energy
prices. Although the volatility in global
energy markets in 2023 is uncertain, the
Directors at present do not foresee
events having a significant negative
impact on the Group’s UK and South
African operations ability to remain in
operation for the foreseeable future.
As a result of the banking facilities held
as well as the acceptable levels of cash
expected to be held by the Group over
the next 12 months, the Directors believe
that the Group has adequate resources
to continue in operational existence for
the foreseeable future and that the Group
is well placed to manage its business
risks. Thus they continue to adopt the
going concern basis of accounting in
preparing the annual financial
statements.
International Financial Reporting
Standards (IFRS)
The Group has adopted all of the new
and revised Standards and Interpretations
issued by the International Accounting
Standards Board (“IASB”) that are
relevant to its operations and effective for
accounting periods beginning 1 January
2022.
A number of new standards, amendments
to standards and interpretations have
been issued but are not yet effective for
the Group. The Group has not adopted
any Standards or Interpretations in
advance of the required implementation
dates. The application of these new
standards, amendments and
interpretations are not expected to have a
significant impact on the Group’s income
statement or balance sheet.
We are committed to improving
disclosure and transparency and will
continue to work with our different
stakeholders to ensure they understand
the detail of these accounting changes.
We continue to remain committed to a
robust financial policy.
Key judgements and estimates
Areas where key estimates and
judgements are considered to have a
significant effect on the amounts
recognised in the financial statements
include:
Life of mine and reserves
The directors consider their judgements
and estimates surrounding the life of the
mine and its reserves to have significant
effect on the amounts recognised in the
financial statements and to be an area
where the financial statements are
subject to significant estimation
uncertainty. The life of mine remaining is
currently estimated at 7 years. This life of
mine is based on the Group’s existing
coal reserves including reserves acquired
but subject to regulatory approval. The
Group actively seeks and evaluates new
opportunities to extend the life of its
existing mining and processing
operations in South Africa. The life of
mine excludes future coal purchases and
coal reserve acquisitions. The Group’s
estimates of proven and probable
reserves are prepared utilising the South
African code for the reporting of
exploration results, mineral resources and
mineral reserves (the SAMREC code) and
are subject to assessment by an
independent Competent Person
experienced in the field of coal geology
and specifically opencast and pillar coal
extraction. Estimates of coal reserves
impact assessments of the carrying value
of property, plant and equipment,
depreciation calculations and
rehabilitation and decommissioning
provisions. There are numerous
uncertainties inherent in estimating coal
reserves and changes to these
assumptions may result in restatement of
reserves. These assumptions include
geotechnical factors as well as economic
factors such as commodity prices,
production costs, coal demand outlook
and yield.
Depreciation, amortisation of mineral
rights, mining development costs and
plant & equipment
The annual depreciation/amortisation
charge is dependent on estimates,
including coal reserves and the related
life of mine, expected development
expenditure for probable reserves, the
allocation of certain assets to relevant ore
reserves and estimates of residual values
of the processing plant. The charge can
fluctuate when there are significant
changes in any of the factors or
assumptions used, such as estimating
mineral reserves which in turn affects the
life of mine or the expected life of
reserves. Estimates of proven and
probable reserves are prepared by an
independent Competent Person.
Assessments of depreciation/
amortisation rates against the estimated
reserve base are performed regularly.
Details of the depreciation/amortisation
charge can be found in note 12.
Provision for mining rehabilitation
including restoration and de-
commissioning costs
A provision for future rehabilitation
including restoration and
decommissioning costs requires
estimates and assumptions to be made
around the relevant regulatory
framework, the timing, extent and costs
of the rehabilitation activities and of the
risk free rates used to determine the
present value of the future cash outflows.
The provisions, including the estimates
and assumptions contained therein, are
reviewed regularly by management. The
Group annually engages an independent
expert to assess the cost of restoration and
final decommissioning as part of
management’s assessment of the provision.
Details of the provision for mining
rehabilitation can be found in note 21.
