Terminology and interpretation notes:

- MM-ECD means Magnetometric Electrical Current Distribution. It is Willowstick's patented controlled-source electromagnetic method and is also called the Willowstick Method.
- MSR means Microseismic Resonance. It is a distinct passive method; MM-ECD and MSR are not synonyms.
- Gamma Scintillation measures naturally occurring gamma radiation. It is an indirect, complementary dataset and does not directly detect groundwater.
- Willowstick results are geophysical measurements and interpretations. Depth, pathway geometry, and confidence are site-specific; direct measurements such as drilling, sampling, piezometers, or hydraulic testing remain important.
- Minerals Canada's 3-component EM constrains conductive responses for mineral exploration; a conductor is not automatic proof of a particular mineral.
