Services / 003

Same team, across the life of the asset.

Three lifecycle phases: design and feasibility, build and commission, sustain and optimise. Independent review and advice for boards, lenders and investors. Delivered by the same multidisciplinary team across mine design, metallurgy, infrastructure, energy and environmental work.

The lifecycle · one team
01
Design & Feasibility
Studies & engineering
Scoping through bankable feasibility, reported to JORC and NI 43-101. Detailed engineering and process design authored by the team that will build the plant.
02
Build & Commission
EPC / EPCM delivery
End-to-end procurement, construction, commissioning and ramp-up. Modular plant, shaft sinking, civil and structural works in remote and extreme environments.
03
Sustain & Optimise
Operations & turnaround
Brownfield expansion, debottlenecking and turnaround of distressed assets. Principals embedded on-site, operations rebuilt, workforces recruited and trained.
04
Review & Advise
Independent assessment
Technical review, due diligence, Competent-Person and fatal-flaw analysis. Authored by senior engineers with operating experience in the asset class.
01 / DESIGN & FEASIBILITY

Feasibility authored by the people who will build and operate the plant.

Westech delivers technical study work from commodity thesis through to bankable feasibility. Scoping studies, pre-feasibility, definitive and bankable feasibility, reported to JORC and NI 43-101 standards. The engineers who author the study are the engineers available to carry the project through design, construction and operation. Studies are designed for the build that follows them, not for the lender's binder.

BLACK DRAGON · SPAIN

Creditor-closure track to US$1B NPV

Westech's redevelopment study recast a distressed asset into a US$1B NPV project with a dual listing.

OTSO GOLD · CANADA / FINLAND

Care-and-maintenance to production in eighteen months

Feasibility and design work underpinned US$20.5M of redevelopment financing and US$70M of renegotiated creditor liabilities.

02 / BUILD & COMMISSION

Plants built by the engineers who designed them.

EPC and EPCM delivery end-to-end for mining, processing, energy and site infrastructure. The same engineers who design the plant carry it through procurement, construction, commissioning and handover. Modular process plant, shaft sinking, civil and structural engineering, including in high-risk, remote and extreme environments. Long-standing industry relationships and a deep network of OEMs support equipment selection, procurement and delivery.

Deliverable set
EPC delivery, end-to-end
EPCM with operator-on-secondment
Procurement & expediting
Long-lead-item management
Construction management & site supervision
Modular process plant

BROWNS OXIDE · NT AUSTRALIA

1.2 Mt multi-metal SX/EW operation

Front-end crushing, leach, CCD and SX/EW circuits delivered for Compass Resources. Copper cathode produced for market.

WOULFE · SOUTH KOREA

7 m adit and plant rebuild, 1.4 to 2.4 Mtpa over four years

Dormant tungsten mine reopened. 5 km underground workings developed; integrated feasibility delivered alongside the build.

03 / SUSTAIN & OPTIMISE

Operations run by the people who design plants.

Westech takes operational accountability at whichever stage an operation requires: brownfield expansion, debottlenecking, turnaround of distressed assets, or operator-on-secondment. The work is operational. Principals embedded on-site, operations rebuilt or scaled, workforces recruited and trained, management systems and reporting structures installed. Engineering continues for the life of the asset.

Deliverable set
Operations review
Plant optimisation & debottlenecking
Brownfields expansion
Turnaround plans
Operator-on-secondment
Workforce recruitment & training
Maintenance & reliability systems
ERP & DCS implementation
Performance reporting & KPI systems
Continuous improvement

Life-of-mine engineering
MINERAL HILL · NSW AUSTRALIA

US$20M annual loss to US$35M annual profit in eighteen months

A loss-making operation returned to profit within eighteen months of Westech assuming operational accountability.

VATUKOULA GOLD MINE · FIJI

1 Mtpa restart at 2,400m depth, two years zero LTI, vended at £80M

Acquired for US$30M, the operation was restarted, the workforce rebuilt to a fully Fijian team, and the asset vended onto the AIM market at an £80M listing valuation.

04 / REVIEW & ADVISE

Capital assessed by the people who build and run the assets.

Westech provides independent technical assessments for boards, lenders and investors making capital decisions. Independent technical review, technical due diligence, Competent-Person and Qualified-Person reports, and fatal-flaw analysis. Reviews are authored by senior engineers who have built and operated assets of the type under review, scoped to the decision.
