Contango’s Lubu: A new coal player for Hwange
That’s why LSE-listed Contango Holdings’ (Contango) Lubu project in Zimbabwe, which comprises a substantial coking coal resource, ticks all the right boxes to deliver a financially lucrative business. GERARD PETER finds out more from executive director CARL ESPREY.
Lubu covers 19 236 ha of the highly prospective Karroo Mid
Zambezi coal basin, located in the Hwange mining district in north-western
Zimbabwe. Historically, around US$20 million has been spent on advancing the
project, including the completion of a pre-feasibility study; resourced
modelling and mine planning; and testwork to confirm the presence of thermal
and coking coal.
Contango started as a shell company looking to acquire a
near-term production asset rather than an exploration asset, and this led to
its interest in and purchase of Lubu.
“Having reviewed multiple assets, it was determined that
Lubu was a project we could bring into production quickly without the need for
years of geological work to validate it. With extensive geological work
completed, to an NI43-101 resource leve,
there was no exploration risk involved in the asset,” explains Esprey.
Esprey adds that the company’s DNA is built upon obtaining a
known resource and building a cash producing asset thereafter. “Even it is
small, the cash generated can then be used to expand without having to lean on
the stock market too much,” he notes Today, the company holds a 70% share in
Lubu with the remainder being held by local partners.
Since 2020, activity at Lubu has been progressing relatively
well, with significant milestones been reached to bring it into production.
However, given a new national lockdown coming into place in Zimbabwe earlier
this year, Esprey expects some delays. That said, in January, the site was
inspected by the Environment Management Agency (EMA) following camp site
rehabilitation and access upgrades that have now been completed.
A meeting with the Binga District Council is due to take
place in the near future to outline the two pit locations at Lubu ahead of pit
development. Contango is currently finalising discussions with the proposed
mining contractor ahead of opening the two pits. According to Esprey, this will be a
significant milestone for Contango and will enable ongoing coking coal offtake
discussions to be finalised.
Furthermore, it will allow bulk samples to be delivered to a
number of multi-national companies who are assessing the viability of
constructing full-scale coke production plants at Lubu.
Lubu has an indicated resource of 702 Mt and an inferred
resource of 510 Mt. Together they comprise roughly 50% coking coal and 50% thermal
coal. The resource exists across 12 seams, with the make-up of each seam and
the percentage of coking coal and thermal coal changing with each seam as well.
“By washing the coal we can determine any variantation of coal that we want and
the only variable will be the yield,” explains Esprey.
Contango aims to mine 100 000 tpm run-of-mine. At that rate
Esprey says that Lubu’s life of mine would be decades, even if the mine had to
ramp up production. “Obviously, as it
gets deeper, the more difficult it will be to mine. Also, a lot of the resource
is thermal coal and this would have to be taken into consideration should our
production focus move in this direction,” adds Esprey.
As Contango opens up trial pits, it will send thousands of
tons of washed coal from different seams to factories in China from which the
impurities will be removed to convert the product into coke. That coke will
then be tested at an independent lab
which will further the discussion with offtakers.
Coke demand never dies
According to Esprey, the closure of thermal coal projects is
having a positive impact on coking coal prices. “Most coal production comprises
a hybrid coking and thermal coal resource. As some of the larger players start
closing down thermal coal projects, they are also taking coking coal out of the
market.
“The demand will not diminish, because you cannot replace
coking coal and this can be seen in the coke price. The price is growing, not
only because of the demand but because of the severe supply constraints. People
are worried that as companies de-risk their businesses by stopping coal
production, there is going to be a shortage of supply.”
As stated earlier, there have been some delays to progress
at Lubu. One of these delays is the fact that Contango hasn’t been able to
finalise offtake agreements with companies that are based in China. This is as
a result of new lockdown regulations in Zimbabwe. “Nothing is going to change until there is
free flowing movement of people between Zimbabwe and China and this will delay
progress at Lubu,” emphasises Esprey.
While Lubu does have significant thermal coal resources,
Esprey confirms that the focus will be on mining coking coal. “Even if you take
half the resources of Lubu, there is enough coking coal to last decades. Also,
the margins for coking coal are better and so is supply and demand for the
product,” he concludes.
