Insights
Stories from the field
Perspectives on mine surveying, geology, compliance, and operational excellence from the GEMS
Consulting team.
Mine Surveying
Survey control: the invisible framework behind every compliant mine
Before a single tonne is moved, a mine needs a defensible spatial framework. Control networks,
benchmark integrity, and disciplined transfer of coordinates from surface to underground are
what separate compliant operations from costly rework.
Across Zimbabwe’s hard-rock operations, GEMS Consulting routinely supports clients at the
point where design meets reality—when pegs, pit shells, and development headings must align
with statutory plans and production schedules. A weak control network does not announce itself
until reconciliation fails, boundaries are challenged, or a statutory submission is rejected.
Our approach combines GNSS and conventional survey methods, rigorous calibration, and
documented QA procedures so that every subsequent survey—whether for volume calculation,
blast hole pickup, or shaft plumbing—rests on data that can be audited, reproduced, and
defended before regulators and investors alike.
Geology & Exploration
From first drill hole to resource confidence
Exploration generates data fast—but value is only unlocked when mapping, logging, sampling, and
interpretation are integrated into a coherent geological model that supports confident
decision-making.
GEMS Consulting supports exploration programmes from early-stage mapping and trenching through
to drill supervision, core logging, and grade control. We work alongside mine owners who
need more than raw assays: they need geological interpretation that connects field
observations to mine planning, ore delineation, and reporting standards.
By aligning geological workflows with survey precision and operational realities, we help
clients reduce uncertainty at the transition from exploration to development—when the cost of
geological misclassification is highest and the need for disciplined data management is
greatest.
Drilling & Blasting
When blasting meets survey precision
Production drilling and blasting demand more than explosive energy—they require pattern design,
collar survey, vibration control, and post-blast reconciliation that keeps pits safe, stable,
and accountable.
In open-pit gold and hard-rock environments, GEMS Consulting integrates blast design support
with survey pickup of hole collars, face mapping, and volume reconciliation after firing.
This closes the loop between planned, drilled, blasted, and mined material.
Restricted blasting, fly-rock control, and compliance with Ministry of Mines requirements are
not optional extras—they are part of responsible production. Our teams bring field discipline
and technical reporting that help operators blast with confidence while protecting adjacent
infrastructure, communities, and the integrity of the mine plan.
