Okane has completed the installation of over 90 instruments to depths of 40 m within waste dump landforms as part of a long-term monitoring and assessment program.

Okane undertook the installation of pore-gas chemistry, temperature, water level, and water chemistry sensors at multiple levels in waste rock and coarse coal reject storage facilities at coal operations in British Columbia, Canada.

Okane was retained to design, implement, maintain, and interpret the performance monitoring system for a tailings facility.

Okane developed a site wide water balance and water quality model for operations and closure of a new gold mine. 

Okane developed a remediation plan for the tailings areas at an abandoned uranium mine site in northern Saskatchewan, Canada.

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.

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.

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.

The main objective of this project was to develop conceptual cover system and landform designs for the waste rock dumps.

Okane undertook development of a mining approval application for a proposed Gold Mine project supported by environmental studies and waste and water management designs.

This project included conceptual water infrastructure design of numerous waste dumps and tailings facilities, spanning over 1000 ha.

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.

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.

Okane has performed evaluations on cover system and landform alternatives for both closing and abandoned mines.

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.

Automated performance monitoring equipment was installed at an active mine in New South Wales.

Okane have investigated waste products for beneficial reuse at mining operations, which involved detailed geochemical assessments.

Okane was engaged to undertake a compliance audit of the base metal mining operations located in Queensland.

Okane provided landform and cover designs for existing waste rock dumps in a high seasonal rainfall climate.

OKC were appointed to provide landform and cover designs for a large, existing waste rock dump containing Potentially Acid Forming (PAF) material.

This project comprised the design of intermediate and final cover systems for the Tailings Storage Facility (TSF) in a high rainfall, seasonal climate.

Okane completed a detailed engineering design and construction plan for remediation of the tailings deposits at an abandoned mine site.
