05 — CAPABILITIES
Quarrying, crushing and delivery — at scale in the north
From the Birimian granite deposit at Pwalugu through crushing plant and haulage fleet to delivery across four regions — Upper Quarry's production and logistics capability in full.
01 — GEOLOGY
What is the Pwalugu granite deposit?
The deposit at Pwalugu is a Birimian muscovite-biotite granite — an igneous intrusion that forms part of the Proterozoic Birimian geological formation across West Africa. The rock is hard, dense and well-cemented, with low water absorption and high compressive strength: exactly the physical properties that make a good construction aggregate.
The mineralogy — quartz, feldspar (muscovite and biotite mica) — produces an angular fracture when crushed, giving concrete the interlocking particle shape that develops strength. The characteristic silver, copper and black granite colour with pink feldspar flecks is what makes it also attractive as ornamental and dimension stone.
The same geological formation hosts the marble-grade material available from the deposit, which has West African export potential for premium flooring and cladding markets.
02 — PLANT & PRODUCTION
What crushing capacity does Upper Quarry have?
Indicative figures — confirm on formal enquiry.
Primary jaw crushing
Run-of-quarry rock processed through primary jaw crushers to reduce blasted material to sub-100mm feed suitable for secondary crushing.
Secondary & tertiary cone crushing
Cone crushers reduce material to the target aggregate sizes, producing the angular particles that give concrete and asphalt their strength.
Vibrating screen plant
Crushed material is screened to grade across the seven product sizes — 6mm through 25mm, quarry dust and crusher-run — for clean separation.
Stockpiling & storage
Graded material is stockpiled by grade at the quarry for dispatch. Pre-production inventory is maintained to support scheduled deliveries.
Blast design & control
Shot-hole drilling and blast design is controlled to produce optimal run-of-quarry material sizing and minimise fines and oversize.
Dimension & ornamental stone processing
Selected blocks are sawn and split to dimension-stone specification; ornamental panels are cut for cladding and paving applications.

03 — HAULAGE & LOGISTICS
How does Upper Quarry deliver aggregate?
Delivery from Pwalugu uses tipper trucks across the road network into the Upper East, North East, Northern and Savannah regions. Haulage is priced by distance from Pwalugu and shown as a separate line item on every quote, so buyers see exactly what logistics costs.
Large or scheduled deliveries are planned in advance against the buyer's construction programme — full truck loads are the efficient delivery unit. Indicative lead times range from same-day ex-quarry collection through to three days for the furthest towns.
All haulage figures on the estimator and this page are indicative. Confirmed haulage rates are set on the formal quote and depend on load size, current fuel and road conditions.

05 — CAPITAL INVESTMENT
Why does capital investment matter to a buyer?
Quarrying is a capital-intensive industry. The drilling equipment, primary jaw crushers, secondary cone crushers, screening plant, conveyors, weighbridges and tipper fleet that supply your project represent a committed, long-term investment that cannot be redeployed overnight. That capital is what separates a supplier with genuine production depth from a trader reselling bought-in material.
For government, institutional and large private buyers, the operational depth behind a supply agreement matters: a supplier with fixed plant at a known quarry face — over forty years in one place — offers a continuity of supply that is difficult to replicate. Upper Quarry's crushing and screening plant at Pwalugu is that depth.
Exact plant specifications and rated throughput are available on a formal enquiry basis to qualified buyers and tender evaluators.
