.... if you read below from Quantecs site, it cuts down on drilling.

3 Ways To Decrease Risk In Mineral Exploration:

1. Avoid uncertainties in the early stages of resource development. More accurate and reliable images of the subsurface prevent unnecessary, expensive drilling. So a large amount of the exploration financial risk can be avoided. When you’re wondering where precious and base metals lie, Quantec surveys help you find more certain drill targets.

2. Present better drill results. Make it easier to get financing for further developing resources. With Quantec’s easy-to-understand interpretations, high-resolution images, and record of better drill core results, investors’ confidence in your site can quickly build. Plus, Quantec’s global success and world presence provides peace of mind to investors.

3. Find mineral targets beneath the surface. Most minerals above 300m have been developed. Quantec helps you image the subsurface of previously explored properties (and mine sites), so you know where to mine next or whether a property is worth further investment.

Why Mineral Companies Like You Really Appreciate Geophysical Surveys

• “Orion 3D told us where the deposit is—and exactly where it wasn’t—helping us avoid unnecessary drilling.” (Nevada Sunrise Gold Corp)
• “Predict what’s there without outcropping.” (Northgate Minerals Corporation)
• “Make new discoveries on existing properties.” (African Copper Plc)
• “Titan 24 images hard-to-reach areas.” (Franconia Minerals Corporation)
• Based on the Titan 24 survey results, drilling intersected with the longest mineral interval ever drilled on the Kemess property.
