Commercial drone mapping: case in point

Silver Standard Resources Inc. is a Vancouver-based mining company focused on the operation, development, exploration and acquisition of precious metal projects. Silver Standard has three operations, including the Marigold mine in Nevada.

In 2016, Silver Standard began looking into a commercial drone mapping solution for its mining operations in North America. Towards the end of the year, Identified Technologies offered a fully managed solution that could provide accurate information in a short period of time and the flexibility to get survey grade data for a wide variety of areas.

Silver Standard recognized several key benefits of the software offered by Identified Technologies, including: cloud-based remote access, quick data processing time, increased accuracy versus manual surveying methods, and access to unlimited flights.

Silver Standard also used a drone to decrease the frequency of its regular site aerial surveys. A drone provides the capability to survey sections of the property where there have been changes on a regular basis, making it possible to extend the period between comprehensive flyovers up to 3 years reducing overall cost. Surveyors are now updating the topography of the mine site every week to measure mining progress, and mine operations is using 3D models in meetings to assist with analysis work. Many departments at the mine site use the drone for a wide range of projects. Current examples include:


  • Construction department: Flying the drone over construction sites allows for monitoring of construction progress. The department can compare the data with cut and fill numbers to assist with cost management and meeting engineering design specs.


  • Process department: Drone surveys of the leach pads allow operators to easily determine which cells are dry (often a result of plugged drip tubing) or locate which areas have too much solution, which helps avoid wasted resource costs, as well as ensure protection of wildlife and alleviate concerns over pad slope stability. By identifying problem areas aerially, operators can immediately respond and repair or make corrections to flow volumes, greatly reducing the foot travel and man-hours required for inspections. By optimizing the solution application, operators are able to maximize gold extraction in the least time possible while reducing potential impacts to wildlife.


  • Technical Services department: Drone technology is used for reporting and reconciliation. The department flew the drone over extraction pits then used Identified’s proprietary change detection technology to compare the progress to designs. In one instance, drone technology was used to survey an area not accessible by foot or light vehicle. Silver Standard found that if it doesn’t need to put people on the ground for surveying, the process can be safer and more efficient.


  • Environmental department: Drones are used to fly over a newly constructed landfill to keep track of the disturbance. Because the mine is allotted a certain amount of acres to disturb, the drone can help efficiently track disturbance in real time, versus using surveyors on foot at the end of a month or end of a quarter. In addition, other environmental uses, such as monitoring dam stability and effectiveness of wildlife protection measures (such as excess solution on the leach pads, or appropriate coverage of process ponds) can be done easily with a quick drone flight.


  • Exploration department: Drone technology has been implemented for many functions. Since Silver Standard can map 100 acres in 10 minutes with a drone, it can update surface topography maps that can be paired with core samples to create block models of potential new exploration areas. Where these areas are remote, the drone can also be used to identify the location of new roads that are needed to move heavy pieces of machinery into place for core sampling.

With traditional methods, it took 20 hours of surveying and processing labor to obtain a detailed survey of a specific section of the mine site. Using Identified Technologies drone solution, the same results were achieved with 1 hour of work. This has allowed Silver Standard to increase speed and productivity, without increasing staffing costs and headcount, while decreasing the frequency of its full site flyovers.
