Highlights

  • Questcorp Mining begins a structured drilling campaign at the La Union Project in northwest Sonora

  • The focus is on carbonate-replacement deposit style mineralisation across four identified zones

  • This marks the initial phase of a broader exploration work commitment following a recent acquisition agreement

Questcorp Mining (CSE:QQQ), a base and precious metals-focused company listed on the All ordinaries, has commenced its first-ever drilling program at the La Union Project in northwest Sonora, Mexico.

The campaign will involve diamond drilling across multiple identified zones within the carbonate-hosted replacement system. This geological style of mineralisation is known for occurrences such as mantos and chimneys, often influenced by structural features surrounding historic workings.

Program targets structurally significant zones

The drill program has been strategically planned to investigate four main areas within the broader La Union terrain. These include the Union Main Mine, North Union Mine, Cobre Mine, and Central Union. Each zone will be evaluated through a dedicated sequence of exploratory holes to delineate mineral continuity.

Operational backdrop and project footprint

Despite extensive legacy activities including historical gold production from the site, modern drilling techniques have not previously been employed at La Union. The new initiative represents the first systematic subsurface investigation undertaken by Questcorp Mining, which seeks to build a geological framework for further exploration stages.

Covering a substantial land package, the La Union Project spans carbonate-rich formations suited for replacement-style systems. Questcorp aims to enhance understanding of mineral distribution and assess mineralised extents near legacy mine workings previously exploited without drill verification.

Acquisition agreement drives first-stage commitments

Earlier in the year, Questcorp Mining formalised an acquisition pathway through a definitive option agreement with a subsidiary of Riverside Resources (TSX-V:RRI). The agreement includes an exploration funding clause, launching with a committed program designed to meet milestone work obligations.

The initial work phase supports the broader commitment across the multi-million staged program, with this first drill campaign constituting an integral component of the exploratory strategy.

Future drilling contingent on initial outcomes

Questcorp’s current drilling initiative is structured as the first pass across select mineralised corridors. Subsequent drill expansion or infill programs may be introduced depending on geological validation and structural correlations identified from the early stages.

This methodical drilling approach is aligned with exploration standards in carbonate-hosted systems, enabling phased evaluations to improve predictive accuracy and resource mapping capabilities.
