What we do


With our presence in Brazil, we offer all the support needed during the drilling campaign execution.

Rods used are currently from Boart Longyear* and we adopt wireline system with PQ*, HQ* and NQ* rods to drill in soil as in rock. We usually drill in PQ/HQ size at the top and reduce to HQ/NQ diameter just after client approval. Holes can be drilled in PQ, HQ or NQ size, as per client preference. The core samples are stored in core boxes that will be identified to indicate name of the hole and depths referring to the core samples kept in that core box.

Drilling Crews

Horizonte Mineiro believes in people, our main asset, and invest in hiring and retaining personnel highly qualified and motivated. We have a network on regional and global scale that will allow reaching personnel from around the globe when needed to fulfill clients request. In terms of processes and techniques available at international level. We rely on personnel with experience in diamond drilling, sonic drilling and reverse circulation.

A typical drilling crew consists of the following professionals:
Drillers (per rig)………………………………………………..(2)
Drilling helpers (per rig)……………………………………(4)
Safety technician (per Project)…………………………(up to 1)
Technical/admin supervisor (per project)…………(2)

Drilling Services Execution

Horizonte Mineiro adopts the best drilling technique that allows obtaining the maximum possible core recovery avoiding loss of valuable information for our clients, in particular in the mineralized zone.

On a daily basis, a Horizonte Mineiro prepares a DDR (Daily Drilling Report) to be delivered to the client for review and signature. The DDR is the base for the issuance of the service invoice.
