v1.3 Phase 1 surface. For geophysical hardware providers and survey-investment decision support. 78 directional cells: Layer A (method × commodity) Sourced from the standard survey-method literature (Reynolds 2011; Telford et al. 1990; Kearey et al. 2002; Sharma 1997; SEG/CGG/BGS/USGS technical publications); Layer B (province × commodity) Sourced from Methodology §07 Table 4; Layer C below Derived by the published composition rule: a cell takes the highest compatibility any of the province's primary commodities exhibits with the method.

* East African Rift seismic is LOW for mining-commodity detection but HIGH for geothermal exploration — a non-mining application outside this view's scope, flagged for geothermal-segment readers. † Kalahari hyperspectral is materially weakened by sand cover; subsurface methods carry compensating weight. Quantum magnetometry/gravimetry: compatibility not yet textbook-established per province — uniform EMERGING rather than invented per-province scores.
Broadest multi-method signal: East African Rift, Arabian-Nubian Shield, Mozambique Belt. Magnetics-and-hyperspectral-concentrated provinces: Tanzania Craton, West Africa Birimian, Hoggar/Tuareg Shield. These are substrate observations for survey-pipeline prioritisation, not commercial implications.
Not a commercial recommendation on any hardware vendor; no vendor is an Afrimintel partner, customer, or counterparty. Not a substitute for geophysical-consultancy survey design — this surface is screening-grade. Not a discovery-success predictor. Not a numeric-precision surface. Proprietary survey data is not published here.
