About Promine's consulting services​

Improve your mine information management with the help of our highly experienced consultants. Through a digitization process, our team will adapt and present the information in compliance with your requirements. Whether it is necessary to protect or manipulate the data, our digitization service also makes it easy for you to share it between different departments. 


Organize your data

Have all your mine information (current and historical) digitized and organized in a database that is easy to access, share, and protect.

Adjust your estimated results to reality

Obtain calculations with greater precision using the information collected to feed the software you use in your routine activities.

Get a geological model and resource estimates

Improve the planning of your mine and increase the value of your project, creating geological and resource models, which will allow you to facilitate the evaluation of various factors of the operation.

What services do we offer?

Our team begins by compiling the information, which is an essential part of the development of the project. Formalized data collection activities are established where it will be necessary to prioritize, identify and process the most relevant data. This information is validated and approved by the mining unit within an agreed period. 

The information is scanned after carrying out a strict validation of the information in which the personnel of the mining unit will collaborate to discard information with errors, high uncertainty, and or not representative. The scanned information is stored in an AWS server and then digitized in AutoCAD or BricsCAD.

The scanned information is then modeled in 3D. The digitized plans are uploaded to a server to be reviewed by our staff. Following, it is placed in a folder accessible to the mining unit personnel for review.  

As a result, you will get:  

  • Digitization of topographic information.
  • Digitization of plans and geological sections.
  • Creation of a database for drill holes and channel samples.

Geology and Geostatistics

Make the most of your exploration results thanks to the cutting-edge tools used by our consultants to carry out their work. We focus on finding and defining the dimensions of the mineral deposits, reducing costs, risks, and work times. 

Using 3D modeling software in conjunction with geostatistical methods, you can obtain the model with the distribution of grades. 

Geological Model (Block Modeling)

Our team reviews, validates and updates the existing geological model. The missing information is complemented for the optimal functioning of the block model. For this, we carry out the process of compositing the grades contained in the drill holes at a constant length (equal), then we proceed to calculate the variogram in all directions (depending on the characteristics of the deposit and the number of samples). Based on the variogram results, the radii of influence and anisotropies are determined. After finding the preferential directions of the mineralization through the experimental variograms, the modeling will be applied with the authorized formulas (spherical, exponential, linear, Gaussian, etc.). At the same time, the geological units that will intervene in the estimation, are defined. 


Geostatistics and estimation will be carried out using 3D modeling software. 

A geostatistical analysis will be carried out to determine the variables that will intervene in the estimation of geological resources, for which the following stages are planned: 

  • Review and validation of databases and elements involved in the estimate.
  • Definition of outliers (extreme values), data capping, and composite length.
  • Construction of semivariograms, definition of the directions of anisotropy, range of variables, and variographic maps.
  • Cross-validation to test the theoretical variogram model and determine if there are estimation errors.

Resource Estimation

Our team performs the description, study, and classification of the resources contained in the deposit since the viability of a deposit can be impacted by a good analysis methodology. Geometallurgical domains generate the possibility of estimating through deterministic methods, such as the inverse of distance, or geostatistical, such as the different variations of kriging, with similar information that is close to it, which has the function of improving the quality of the estimates. Additionally, an estimate is made for various cut-off grades, and variance maps are generated. Finally, a classification of geological resources is made: Measured, Indicated, and Inferred, according to the requirements of the mining unit.
