Precious Metal Mine, Ontario, Canada
Okane developed a site wide water balance and water quality model for operations and closure of a new gold mine.
Mine Site Northern Saskatchewan – Tailings Remediation Plan Quality Control / Quality Assurance Program
Okane developed a remediation plan for the tailings areas at an abandoned uranium mine site in northern Saskatchewan, Canada.
Legacy Mine Site, Western Australia (Geochemistry)
Okane designed a large scale sonic drilling investigation program of a number of waste rock dumps which included the installation of monitoring instrumentation within the waste, and the geochemical and geophysical testing of waste materials in the Okane laboratory.
Legacy Mine Site Pilbara (Mine Closure Design)
Okane completed calibration and predictive soil-plant-atmosphere modelling, designed and instrumented cover system field trials for flat and sloping areas, and interpreted field performance monitoring data over a 15 year period.
INAP How to Build a Better Waste Rock Dump
Okane, in partnership with Earth Systems, is in the development stages of a document for the International Network for Acid Prevention (INAP) for building better waste rock piles.
Historical Mine Site Northern Australia
The main objective of this project was to develop conceptual cover system and landform designs for the waste rock dumps.
Gold Mine, Queensland, Australia
Okane undertook development of a mining approval application for a proposed Gold Mine project supported by environmental studies and waste and water management designs.
Gold Mine, East Africa
This project included conceptual water infrastructure design of numerous waste dumps and tailings facilities, spanning over 1000 ha.
Forensic Assessment of Historic Waste Rock Storages for Large Base Metal Mine, Queensland, Australia
Okane undertook investigation of three waste rock storages associated with a large base metal mine where the construction details were unknown to the current mine operators.
Field Performance Monitoring, Nova Scotia, Canada
The services of Okane were retained to install instrumentation to facilitate evaluation of cover system performance over time under site-specific climate conditions at a series of historic mine sites in Nova Scotia, Canada.
Evaluation of Design Alternatives for Tailings and Waste Rock, Canada
Okane has performed evaluations on cover system and landform alternatives for both closing and abandoned mines.
DumpSim
Okane has developed the DumpSim assessment tool, based around a semi-quantitative risk assessment approach for integrated assessment of waste rock management alternatives, as well as in situ WR conditions.
Cover System Performance Monitoring, New South Wales
Automated performance monitoring equipment was installed at an active mine in New South Wales.
Beneficial Use of Waste Streams for Mine Site Rehabilitation, New Zealand
Okane have investigated waste products for beneficial reuse at mining operations, which involved detailed geochemical assessments.
Base Metals Mine, Queensland, Australia
Okane was engaged to undertake a compliance audit of the base metal mining operations located in Queensland.
Base Metals Mine, Northern Australia (Water Management)
Okane provided landform and cover designs for existing waste rock dumps in a high seasonal rainfall climate.
Base Metals Mine Northern Australia (Mine Closure Design)
OKC were appointed to provide landform and cover designs for a large, existing waste rock dump containing Potentially Acid Forming (PAF) material.
Base Metals Mine Northern Australia
This project comprised the design of intermediate and final cover systems for the Tailings Storage Facility (TSF) in a high rainfall, seasonal climate.
Abandoned Tailings Facility Construction, Canada
Okane completed a detailed engineering design and construction plan for remediation of the tailings deposits at an abandoned mine site.
Testimonials
The Technology Development group supporting Albian mines at CNRL had been a M A Okane client for a number of years, and I am very pleased with their services.
For our field projects Okane provides a number of support activities including field instrumentation, survey and monitoring. I found the Okane team to be very active, energetic and flexible to adjust to the client’s need on a relatively short notice which is a core requirement for our projects. I highly recommend M A Okane’s services, and expect that they would continue their excellence in the future.
CNRL – Albian Mines
Your team has advanced mine closure planning at our site more in the last month than we’ve seen in the last five years.
