    Cementation Africa early dewatering designs: key lessons for mine planners

    July 20, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Cementation Africa is pushing for underground mine dewatering to be designed from the earliest study phases, with hydrogeological investigations embedded in scoping and pre-feasibility work rather than added after shaft sinking. Study Manager Mine Engineering John Goulding stresses that early characterisation of aquifers, inflow rates and pore pressures allows proper sizing and siting of pump stations, sumps and grout curtains, and integration with shaft and decline layouts. For geotechnical and mine planners, this approach reduces unplanned inflows, avoids costly retrofits and supports more reliable ground support and excavation sequencing.

    Technical Brief

    • Pump station caverns and access drives are dimensioned early to accommodate staged pump upgrades and redundancy.
    • Early dewatering design explicitly considers safe access for pump maintenance, pipe replacement and emergency power routing.

    Our Take

    Cementation Africa’s focus on embedding dewatering into early-stage designs aligns with its shaft upgrade work at Mopani’s Mindola copper shaft, where long-life hoisting and water management performance will be tightly coupled in practice.

    Across our database of 1241 Mining stories, Cementation Africa appears repeatedly in technically complex underground work (Mindola, Tharisa’s underground transition, strategic fleet management), so formalising dewatering early on signals an attempt to standardise risk controls across a growing portfolio rather than treating water as a project-by-project add‑on.

    The recent strategic ownership transition involving Cementation Africa, Cementation Americas and Terra Nova Technologies suggests that more integrated early-stage design inputs (like dewatering) could become a group-wide differentiator when bidding for deep or high-water-risk underground contracts.

    Central banks double gold-buying pace: price and project signals for mine planners

    Central banks have doubled their gold purchases to an average 1,000 tonnes per year over the past four years, with a World Gold Council survey of 76 institutions showing 89% expect global official holdings to rise and 45% plan to add to their own reserves. Speaking at the Rule Symposium in Boca Raton, senior market strategist Joseph Cavatoni framed the move as a structural response to sanctions, inflation and credit risk in paper currencies. The deeper, policy-driven demand base could underpin bullion prices, but miners still need to convert higher prices into disciplined production, cash flow and managed political and operating risk.

    Tactical Resources’ Nasdaq move: tailings-first Texas REE project lens for engineers

    Tactical Resources has secured Nasdaq Capital Market approval via a SPAC merger with Plum Acquisition Corp. III, with New PubCo shares to trade under the ticker “TREO” after the expected 28 July 2026 closing. The company plans to use the listing to accelerate its Peak rare earths project in Hudspeth County, Texas, which holds exclusive rights over about 4 million tonnes of REE-bearing tailings and stockpiles from the Sierra Blanca quarry and already has initial quarry operating permits. Tactical’s feedstock-first model relies on existing mined material, aiming to bypass new mine development and move directly into processing.

    Copper price surge on China demand, Chile losses: key signals for mine planners

    Copper climbed 1.3% on Comex to $6.35/lb (just under $14,000/t), within 5% of its early-June record, as China’s import premium hit $100/t for the first time since May 2025 and Shanghai exchange stocks fell 20% last week to 79,909 t, down 45% year-to-date. Tightness is being driven by Beijing’s VAT crackdown on the “invoice economy”, pushing substitution from scrap into cathode and drawing metal out of LME warehouses despite record 630,293 t in Comex storage. On the supply side, storms cut South32’s payable output at Sierra Gorda to 16,000 t for the June quarter, Antofagasta’s H1 production dropped 9.5% to 285,000 t with cash costs guided up to $2.40–$2.60/lb, and Codelco halted surface operations at Andina and shipments from El Teniente.
