Interpretation
Forecasting layout is well visualized and is easily interpreted when perspective probable sectors are selected under the following categories:
- extracted depth ore signal is divided in values on ranks (similarity) and quantities (approximate ore resourses) of correspondence to reference ore mineralization;
- scale effects become well apparent on prognostic layout. Ore field generally forms a zone of higher dispersed mineralization with separate accumulations of ore bodies;
- forecast may be a slightly shifted (up to 500-600 m for geoscanning scale 1:50000-1:25000) from the real position of ore bodies. Presumably as the scale of geoscanning becomes larger, the forecast areas are more and more localized and shifted to the real position ore mineralization;
- bubbles accumulation with high value ore signal more than 9 - 12 (i.e. with size typical for ore bodies of particular ore field) means that mineralization will be commercial with very high (close to 100%) probability level; i.e. bubble accumulation is interpreted as an ore body or deposit and maybe of different configuration depending on morphological type of mineralization. Mineralization in single bubbles with ore signal interpreted as unprofitable. In the others cases the probability of mineralization detection is negligibly small;
- depth of forecast mineralization corresponds to the depth of reference mineralization;
- having additional data characterizing geological structure of the area, criteria for selection of perspective probable sectors are extended and defined more precisely.

Conclusion
Method allows selection of perspective areas at the depth with ore formation and parameters similar to standard one.
Obtained prognostic layout of ore mineralization maybe compared with not completely developed photo.
Accuracy of ore signal extraction corresponds to the scale of topographical map, i.e. using a map with 1:10000 scale possibilities of the method allow contouring ore bodies in detail and with high precision. Accuracy of ore signal extraction also depends on precision of contours of reference ore mineralization.
Accuracy of extraction of depth ore signal correspond to scale of topographical map and use map of scales 1:50000-1:25000 means of method makes it possible with sufficient accuracy and precision select deposits, and use map of scales 1:10000-1:2000 – even ore bodies. Accuracy of extraction of depth ore signal depends on precision of outlines and complete of reference ore mineralization too.
Geoscanning method allows operating data of continuous tests in each point of area due to a possibility of measuring relief parameters. A large set of each "sample" will most probably denote mineralization. This is confirmed by the results of exploration works because availability of enormous number of samples (up to dozens of thousands samples per 1 km2) allows contouring ore bodies uniquely.
Method determines unknown hidden and overlapped deposits at any depth. When method works it uses basis .isolines of topographical map without coordinates and outlines and/or points on reference mineralization.
Expected result of our forecast is very high - every 3rd drill hole or mine working will contain ore.
Accuracy of forecast is also very high (up to detection of ore bodies) and decrease exploratory drilling and thus reduces cost and time of operations.
Method discovers unknown hidden resources on deposit flanks. A well-known deposit can be just a small part of an unknown so far large hidden object.
Method can choose better objects and the most perspective, with highest increase of unexplored resources objects from the number of not large and insufficiently explored deposits of the same kind.
Method is quite universal for exploration of different mineral resources.
