Ground Magnetics

Caption:

Traditionally, ground magnetics is an effective tool for locating geological structure rapidly and accurately from the surface. We have forged the plight of making this practice and industry standard in both mineral and, more recently, coal mining, prior to any drilling.

Our process covers more ground safely, with the largest fleet of magnetometers and crew, using both in-house industry standard software for our data processing, interpreting and reporting.

With over three decades of industry experience, Ultramag Geophysics continue to lead in ground magnetic surveys in Australia. With a 90% hold on ground magnetics’ market share in the coal industry, we have successfully located more dykes, sills, faults and other hazards than any other Australian geophysical company.

Deep Ground Penetrating Radar

Caption:

Developed with state-of-the-art technology, Deep Ground Penetrating Radar (DGPR) is a breakthrough geophysical technique offering images of unparalleled resolution; up to 100m from the surface in ideal conditions and, routinely 50m.

We have successfully mapped the following using DGPR:

  • Porphyries 
  • Lithium Pegmatites
  • Veins and shears 
  • Alluvial deposits and covers
  • Alteration zones 
  • Dykes
  • Faults
  • Sills
  • Folds
  • Voids
  • Massive sulphides 
  • High and low sulphidation ore systems
  • Ground water mapping, aquifers
  • Paleo channels.

We also use our DGPR for geotechnical surveys, mapping voids, concrete thicknesses, bedrock and any other information pertinent to structural integrity.

Some notable DGPR highlights are its rapid acquisition, quick data turn around, high resolution, cost effectiveness, and ability to cut drill programs by up to 75%.

Seismic

eVibe Seismic!

Cost effective, Safe, amazing results!

Our electromagnetic sources are able to undertake frequency sweeps of any design, with full force possible from 2Hz using the 10kN Storm, or 8Hz using our small remote control Lightning.
As frequency sweeps can be custom designed, sufficient 4Hz-8Hz energy can often be transmitted into the ground using the Lightning by simply designing a sweep that dwells at the lower frequency range - the Lightning is capped at 1000Hz top frequency.

In the comparison below, it can be seen that although the 1.7kN system applies 1/100th of the force to a conventional Univib hydraulic system, but high efficiencies of this system mean as good or better quality data to a similar depth.

A full range of sources available for various depths of penetration, 1.7kn (to 1000m), 3.6kn (to 2000m) and 10kn (to 3000m or more) 

  • High resolution from near surface to depth
  • Affordable for junior and mid tier explorers
  • High resolution from near surface to depth
  • Safe remote control unit
  • Small acquisition teams of generally 3-5
  • Silent, small footprint/ environmental and farmer friendly (minimal or no clearing for lines needed)

Micro Gravity

Caption:

For 15 years, Ultramag have used industry leading gravity meters offering high resolution microgravity.

Applications for Ultramag microgravity include:

  • Mapping the structure of sedimentary basins including faults and depth
  • Water drawdown (4D) in oil reservoirs
  • Locating a range of placer and hard-rock mineral deposits
  • Finding kimberlite (diamond) pipes
  • Copper gold porphyries
  • General geological mapping including buried granites.

We have also utilised microgravity for a number of geotechnical application including:

  • Map depth of alluvial cover, including beneath swamps
  • Locating voids in Karst topography
  • Tunnels, shafts, stopes and adits.

Ultramag Gravity is non-destructive and non-invasive.

Ground Deployed Spectrometry

Caption:

Our Gamma Ray Spectrometry (GRS) is used in aircraft, ground vehicles and in boreholes to map the abundance of radioactive isotopes of thorium, potassium and uranium.

the Ultramag PicoEnvirotec spectrometer service offer rapid acquisition and is quad, hand-carried or helicopter mounted. It is a non-destructive, rapid and inexpensive tool limited to the top 1-2m.

Uses include:

  • Mineral exploration (especially uranium)
  • Coal exploration
  • Soil mapping
  • Site contamination (ie Monazite waste from mineral sand processing).
