Epicentre

Epicentre is HiSeis’ custom built, cloud hosted, end-to-end user interface.

Through Epicentre, our clients can track and manage their project from the first engagement with HiSeis through to the real-time tracking and mapping of acquisition programs and across processing, interpretation, delivery of data and identification and tracking of drill targets and drilling campaigns.

Epicentre keeps all information in one place, allows new staff members to quickly get up to speed on the entire history of legacy projects and acts as a repository for all data, presentations, contracts and deliverables.

Seisomics

Seisomics is a 3D Geobody Modelling workflow that automatically extracts geological features, such as intrusions, from 3D seismic data using a HiSeis proprietary algorithm.  Seisomics leverages unconstrained machine learning and textural classification to partitian seismic volumes into regions of different geological/lithological composition. 

Seisomics is particularly effective in identifying regions of unique textural facies that are often associated with intrusions.  These regions can then be brought in as structural constraints within inversion workflows for gravity, magnetics, and electromagnetic methods resulting in better resolved petrophysical properties including density, magnetic susceptibility, and electrical conductivity which can be used to target mineralization with enhanced confidence. 

Comet

The Comet workflow is a rapid whole rock mineralogy algorithm that converts input geochemical assay data into calculated mineral compositions. This dataset has proven to be an extremely exciting new development which, when used in conjunction with HiSeis 2D and 3D property propagation algorithms, provides never before seen mineralogical detail in both 2D and 3D datasets.

Property Prediction

2D and 3D seismic data provides unmatched structural resolution which is maintained with depth. It is for this reason that seismic data features as a cornerstone dataset for the propagation of measured borehole data (ground truth data) between and beyond the borehole. Seismic data provides the framework within which all other data can be intuitively projected into 2D and 3D space.

HiSeis has actively developed their Propagation and Prediction algorithms, using active seismic datasets to push drill hole sensor data into 3D space, providing high fidelity property prediction.

TOP-ROCK

TOP-ROCK utilises seismic refraction tomography to generate a detailed 3D model of the near-surface velocity variations within a project area. This data can be generated directly from a seismic dataset, or can be further optimised through calibration with available drilling. The output wireframe can identify vertical changes in the near-surface velocity down to a few metres of resolution.

Velocity variations in the near surface are directly related to seismic rock competency and hence, a detailed map of the velocity field provides a high-resolution map of near surface conditions, highlighting key features such as the position of depositional structures, alteration and bedrock lithology changes.

TOP-ROCK can define the extent of free-dig material and provide important input for the design of pit-wall stopes , infrastructure placement and engineering specifications.

TOP-ROCK can help define the extent of oxide material and produces a physical wireframe to assist in analysis and calculation of ore recovery.

TOP-ROCK depth to bedrock models naturally highlight the undulations and variation in the bedrock contact. This can create detailed maps on the location and connectivity of paleochannels and air in more accurate calculation of near surface aquifer volumes

FAULT-MOD

FAULT-MOD generates a highly accurate, unbiased probability volume that maps the distribution of faults in the subsurface at mine site scale and down several kilometres into the subsurface.

Faults are often focal points for mineralization during the formation of an ore deposit.  Understanding the fault trends and relationships in 3D can have a direct impact on drill targeting in exploration.

Identification of post mineralization faulting can also provide valuable input into mine design and risk mitigation as fault zones may affect the integrity of underground mine workings. Our continuous 3D fault models provide a new level of input into mining to reduce the costly risk of unexpected events such as caving deviations, pit wall failures or difficulties during shaft sinking and other underground development.
