The Emerald Turned to Stone: Sandawana’s 39.9-Million-Tonne Lithium Resource, the Certificate, and the Plant That Isn’t Built Yet
The mine that gave the world its finest emeralds has certified something new. An independent, JORC-compliant assessment has confirmed 39.9 million tonnes of lithium resource at Sandawana’s Block A — with an unusually high 72% classified as measured, the highest grade of certainty. It is genuinely bankable, wholly Zimbabwean-owned, and real cause for pride. But the certificate covers only 30% of the claim, the processing plant is still at feasibility stage, and the export ban that was meant to force value addition arrives in five months. This entry separates the achievement from the announcement.
A Real Milestone, Stated Precisely
On Wednesday 22 July 2026, at a briefing in Harare, Mutapa Energy Resources — the state mining company, successor to Kuvimba Mining House — announced that an independent assessment conducted under the internationally recognised JORC Code had certified a 39.9-million-tonne lithium resource at the Sandawana project in Mberengwa. Chief executive Innocent Rukweza said the resource had been confirmed by a competent person, which is precisely what makes it bankable — the technical threshold international lenders and investors require before they will fund a mine.

The figure that genuinely distinguishes Sandawana is not the tonnage — it is the quality of certainty. Of the 39.9 million tonnes, about 28.7 million (roughly 72%) is classified as “measured”, the highest confidence category in the JORC hierarchy. Rukweza claimed this makes Sandawana the first Zimbabwean mine with measured resources at 72% of the total.
JORC is a rulebook. It stands for the Joint Ore Reserves Committee, an Australian-born standard used worldwide to stop mining companies from exaggerating what is in the ground. Under JORC, a qualified independent expert — a “competent person” — must sign off on the numbers, staking their professional reputation on them.
Why it matters: a bank will not lend hundreds of millions against a rumour. Before Sandawana had this certificate, its lithium was a promising story. After it, the resource is a documented asset a lender can underwrite. That is the difference between “we think there is lithium here” and “an accredited expert confirms 39.9 million tonnes, and 72% of it to the highest standard.”
But — and hold this thought — bankable is not the same as banked. A resource being fit to finance does not mean the finance has arrived, the plant is built, or a single battery-grade tonne has been produced. It means you are now allowed to knock on the door.
The Mine That Gave the World Its Emeralds
Zimbabweans should know what this place is, because it carries a lesson older than lithium.
Sandawana, in Mberengwa, was for decades one of the most famous emerald mines on earth. From the 1950s its stones — small, but of extraordinary depth of colour — were prized by the world’s finest jewellers and set a global benchmark for quality. The name Sandawana meant something in Geneva and New York long before anyone spoke of battery minerals. This is not a new mine. It is old ground, giving up a new stone.
And there is a hard historical truth folded into that pride. For most of that emerald century, the gems left Zimbabwe rough. The cutting, the polishing, the setting, the branding, the enormous markup — all of it happened elsewhere. A stone worth a little at the mine mouth in Mberengwa became worth a fortune in a shop window in Europe, and almost none of that difference stayed here. We dug the beauty; others sold it.
Under Kuvimba, and now Mutapa Energy Resources, the mine strategically shifted from emeralds to lithium after exploration revealed the scale of the deposit. And here is the fact that gives this story its weight: Sandawana is described as the only major lithium mine in the country wholly owned by Zimbabweans, through the state. Most of Zimbabwe’s producing lithium — Bikita, Arcadia, Kamativi and others — sits under substantial Chinese ownership. Sandawana is the national exception, and that is exactly why what happens to it matters beyond its tonnage.
Thirty Per Cent of One Claim — and Why That Cuts Both Ways
Now the number the celebratory headlines rushed past, and which this journal insists on placing at the centre.
The certified 39.9 million tonnes comes from Block A alone — about 30% of Sandawana’s 3,800-hectare claim. The remaining 70%, Blocks B and C, has not yet been drilled to JORC standard; geochemical and geophysical work is under way. Management’s stated ambition is to upgrade the total resource toward 90 million tonnes, and older reporting has floated figures around 100 million.
This cuts two ways, and honesty requires both. The optimistic reading: if 30% of the claim holds nearly 40 million tonnes at this quality, the full concession could be one of the more significant lithium assets anywhere — enormous upside. The disciplined reading: 90 million tonnes is not a resource, it is a hope, and this journal has watched too many African mineral announcements quote the dream figure as though it were money in the bank.
The right posture is to celebrate exactly what was certified — 39.9 million tonnes, 72% measured, at Block A — and to treat everything beyond it as promising exploration that must itself be drilled, sampled and signed off by a competent person before anyone banks it. Bankable means Block A. The rest is still a question mark, however hopeful.
A Certificate Is Not a Plant
Here is the tension at the heart of this announcement, and it is a serious one.
Zimbabwe has banned the export of lithium concentrates from 1 January 2027. The policy — which this journal supports in principle — is meant to force value addition: no more shipping out semi-processed rock, process it into battery-grade material here, capture the value at home. The ban follows the 2022 ban on raw ore and a February 2026 emergency clampdown after stockpiles were found at the port of Beira.
And here is the difficulty. As of mid-2026, Sandawana’s processing plan was still at feasibility study stage — behind peers. Huayou Cobalt has already built its plant and is exporting lithium sulphate; Sinomine’s Bikita and Yahua’s Kamativi are under construction. The state’s own flagship — the one wholly-owned Zimbabwean asset — is the furthest from complying with the government’s own deadline.
So the lithium producers, chaired by Sandawana’s own chief executive, have formally asked government to move the deadline to June 2027 — not to abandon beneficiation, but because plants under construction physically cannot be finished in time. It is a reasonable request, and it exposes an awkward truth: the government has set a hard deadline that its own mine cannot yet meet. Enforcing a ban the state itself would fail is a credibility problem; softening it for everyone risks the whole value-addition policy that Zimbabwe’s future depends on.
Where Sandawana Sits Today — and Where the Money Is
Lithium, like our granite in Entry 49 and our emeralds before it, is worth a little at the bottom of the ladder and a fortune at the top. The certificate confirms the resource. It does not move Sandawana up a single rung. That takes the plant.
Because this is the difference between a job and a fortune. If Sandawana ships crushed rock, it earns a mine-mouth price, employs a modest crew, and the real money — the chemistry that turns rock into battery material — is made in China and captured there.
If Sandawana builds the sulphate plant, Zimbabwe climbs the ladder — more skilled jobs, chemists and engineers and technicians, a higher price per tonne, and an asset that, under the BOT deal, eventually belongs to the nation. Same rock. Utterly different future. The entire question is whether the plant gets built before the resource gets shipped.
What This Certificate Delivers, and What It Does Not
The Balance Sheet of the Announcement
Bankability — an independently verified resource lenders can underwrite.
Exceptional certainty — 72% measured is a strong, investor-friendly number.
National pride and ownership — a world-class asset wholly Zimbabwean-owned.
Leverage to court finance for the US$700m Block A build.
Proof of scale — and huge upside across the unexplored 70%.
It does not build the plant. Processing is still at feasibility stage.
It does not certify 90 million tonnes. That is ambition, not resource.
It does not meet the 2027 deadline. The state’s own mine is behind.
It does not produce one battery-grade tonne. No value added yet.
It is not finance in hand. Bankable is permission to ask, not money received.
Five Things to Watch, and One to Build
Do Not Ship the Emerald Twice
Let me say the good part without hedging, because it is real. This is a genuine achievement, and a Zimbabwean one. A wholly national asset, certified to an international standard, with a measured-resource share that would make any mining financier sit up. The team that drilled 103,000 metres and spent US$24 million to produce a number a bank will respect deserves the country’s congratulations. Makorokoto. And it is fitting that the ground doing this is Sandawana — old, proud ground that has given Zimbabwe treasure before.
But that history is exactly why I cannot let the celebration stop at the certificate. Sandawana has already taught this country one lesson, and we paid for it in emeralds. For half a century the most beautiful green stones on earth left this soil rough, and the fortune was made in other people’s shops. We got the hole in the ground; they got the jewellery. If we now certify 40 million tonnes of lithium, ship it as concentrate because the plant wasn’t ready, and buy back the battery — we will have shipped the emerald twice. Same mine. Same mistake. A different mineral to be ashamed of.
The whole game is the plant. Not the certificate — the plant. The certificate is a fine thing; it is a ticket to the room where the money is. But Zimbabwe has a long and painful history of announcing tickets and never quite entering the room. The 2027 ban was supposed to be the forcing function — the discipline that says: build the plant, or lose the right to export. And now the state’s own flagship is asking for more time. I understand why. But understand what is at stake: if the rule bends first for the government’s own mine, every private miner will demand the same, and the value-addition policy that is Zimbabwe’s single best economic idea in a generation will quietly die of exceptions.
So my counsel is the same as it was for granite in UMP, for the tourism fund, for every door this journal has watched open. The asset was never the problem. Zimbabwe’s ground is generous — emeralds yesterday, lithium today, and more tomorrow. The problem has always been that we stop one rung too low and let someone else climb the rest. Build the sulphate plant. Publish the transfer clock. Train the chemists. Hold the line on 2027 or move it honestly for everyone. Do that, and Sandawana becomes the place where Zimbabwe finally kept the value it dug.
Nyika inovakwa nevene vayo — uye zvinobva muvhu redu zvinopedziswa muno. A country is built by its owners — and what comes from our soil must be finished here. Ziva kwakabva ibwe iri: rakatanga riri emurara, zvino ratova ibwe rebatani. Know where this stone came from: it began as an emerald, now it is the battery’s stone. Let us not sell it raw a second time. Pamberi nekupedzisa, kwete kutumira zvisina kupera. Forward with finishing — not with shipping the unfinished. Tigashire.
