About Us


Holmes Mining Consultants Ltd. (HMC) was founded in 2018 by Derek Holmes as a boutique consulting firm seeing the need for specialized permitting and compliance work in British Columbia’s mining sector, specifically stone, sand and gravel projects.  The company has since expanded and provides remote sensing (drones) services alongside mine planning and design.  Derek has worked in the aggregate industry for more than 20 years, understands the unique challenges that mining projects face and can guide applications through the maze of regulatory steps for successful completion.

HMC works closely with a number of specialized professionals to complete the necessary studies to put forward successful applications including geotechnical services and rock testing, archaeology, hydrology, agrology and engineering.

Our goal is to grow into BC’s most trusted resource in the aggregate sector and continue to provide clients with honest, straightforward advice and services with the utmost care and attention.

Working with us will give you a calm sense of being with the right company for all the right reasons.



  • Matrice 300 RTK
    Matrice 300 RTK

    Here at Holmes Mining Consultants, we use only the finest "next-level" drone technology. The MATRICE™ 300 RTK is a powerful industrial drone platform with an advanced flight controller system, 6 Directional Sensing and Positioning system and FPV camera. To enhance reliability and safety, it also supports CSM Radar & LiDAR – an additional obstacle detection component that can be mounted on top of the drone. It features several advanced flight functions including return-to-home, obstacle sensing, AI spot-check and more. The built-in AirSense provides awareness of nearby aircraft within the surrounding airspace to ensure safety. Its airframe design gives it an IP45 Ingress Protection, in accordance with the global IEC 60529 standard. The mechanical design, along with quick-release landing gears and mounted folding arms, makes it easy to transport, store and prepare for flight.

    DJI Mavic 2 Pro

    A drone that embodies all of DJI's advanced, signature technologies, and is able to redefine what is possible for the world of aerial photography.

    Mavic 2 Pro - Features

    Mavic 2 Pro is still quite portable. It fits nicely in a camera bag, taking up about the same space as a typical 70-200mm f/2.8 zoom lens. You'll have to make a little more space for the remote control, charger, and any extra batteries you buy, but you won't have to dedicate a backpack to the Mavic as you do with the Phantom design.


  • LiAir V70
    LiAir V70

    The LiAir V70 is a lightweight UAV or sUAS-mounted LiDAR survey instrument designed and produced by GreenValley International (GVI). This system features a Livox AVIA laser scanner and it is one of the most cost-effective LiDAR systems in GVI’s LiAir Series. This lightweight 3D surveying and mapping payload was designed with DJI’s Matrice 600 Pro & DJI M300 RTK & DJI’s Matrice 210 series platforms. LiAir V70 is able to provide highly accurate 3D point cloud data and is a great fit for applications in a wide variety of industries including forestry. And it also provides an option to be equipped with a high-definition digital camera, which can be used to generate photogrammetry products as well as true color 3D point clouds.
