For a fertiliser, the customer is a farmer, and the farmer’s question is simple: does this input arrive, does it work, and can it be afforded. A mining announcement on the Red Sea coast is a long way from that farmer’s field, but every producing mine is ultimately judged by whether it changes those three answers. That is the test worth applying today.
Africa Finance Corporation has invested US$50 million in the Colluli potash project, supporting a long-life sulphate-of-potash resource near the Red Sea. Sulphate of potash is a premium, chloride-free product used on high-value crops. Read through the customer, the relevant question is not the size of the resource but whether it eventually reaches buyers as better access, steadier supply or a fairer price.
The Customer Problem: A scarce, hard-currency input
Across East Africa and the Horn, potash is an imported product bought in hard currency, which makes it expensive and its supply uneven. For the farmer, that shows up as an input that is sometimes unavailable, often costly, and rarely tailored to local soils. The customer problem is access and affordability before it is anything else.
A producing Colluli, aimed at global markets but sitting close to regional farmland, could over time shorten the journey between production and buyer. The regional supply rationale for the project points to exactly this: a nearer source of a nutrient the region currently imports from far away. Nearer supply is the precondition for better access, even if it does not guarantee it.
Takeaway: the customer problem is a scarce, dear, distant input, and proximity is the first lever against it.
The Pricing Question: Who captures the saving
Proximity can lower delivered cost, but who keeps the saving is a separate matter. Between the mine and the farmer sit traders, blenders, distributors and agro-dealers, each able to pass value on or absorb it. A producing source could translate into lower farm-gate prices, or it could simply improve margins along the distribution chain while the farmer pays much as before.
This is the pricing discipline the customer lens demands. Cheaper potash at the port is not cheaper potash in the field unless competition and distribution pass it down. In thin markets with few distributors, a cost saving upstream can be absorbed entirely as margin before it ever reaches a buyer. The measurable indicators are the farm-gate price of potassium inputs and their availability by season — not the tonnage leaving the mine.
Takeaway: a nearer source lowers the customer’s price only if distribution is competitive enough to pass the saving on.
The Relationship: Who owns the customer
Behind pricing sits a quieter contest over who owns the farmer relationship. Fertiliser reaches smallholders through agro-dealers, cooperatives, input-finance schemes and increasingly digital platforms. Whoever holds that last-mile relationship — and the data that comes with it — captures a durable position that the mine itself never touches.
For consumer-facing and agri-input firms, that is where the opportunity created by a new regional source actually lands. A producing Colluli enlarges the pool of product that needs to be blended, branded, financed and delivered to buyers. The firms that own trusted access to farmers stand to benefit regardless of who digs the ore.
Takeaway: the durable consumer prize is the last-mile relationship with the farmer, not the mineral upstream.
