OptiSeis Solutions Ltd. Successfully Completes Innovative, Ultra-Low-Impact Seismic Survey along the McLaren Lake Fault Zone of Canuc's ESP (East Sudbury Project) in Greater Sudbury, Ontario, Canada - Advancing the Future of Mineral Exploration

Rhea-AI Summary

Canuc Resources (OTCQB: CNUCF) reported that OptiSeis Solutions has successfully completed an innovative, ultra-low-impact 3-D seismic survey along the McLaren Lake Fault Zone on Canuc’s 100%-owned East Sudbury Project near Sudbury, Ontario. The program covered about 13.5 km of lines, all on existing roads, was finished in seven days, and used 1,355 autonomous nodal sensors, two IVI Minivibrators and more than 2,700 source points to generate a dense subsurface dataset.

According to Canuc, Natural Resources Canada also acquired a Vertical Seismic Profile using fibre-optic cable in three wellbores, providing complementary data. The company expects this work to generate direct exploration targets for MIAC and IOCG-style deposits near historical copper-gold workings and plans follow-up work alongside a property-wide gravity gradiometric survey.

Innovative 3-D Seismic Survey

OptiSeis Solutions Ltd. ("OptiSeis" or the "Company") is proud to announce the successful completion of an innovative mineral exploration seismic survey along the northern section of the McLaren Lake Fault Zone on Canuc's East Sudbury Project located within the Greater Sudbury Region of Ontario, Canada - one of the world's premier and most storied mining districts. The seismic survey completed by OptiSeis has delivered a rich, high-quality subsurface dataset that will now be used for targeting large-scale, regional mineral potential along the McLaren Lake Fault Zone (Figure 2 - ESP Fault Structures & Area of Survey).

Survey Precision & Efficiency

The seismic survey program covered approximately 13.5 kilometers of total line length - with every meter of seismic acquisition conducted along existing roadways to minimize environmental disturbance and community impact. Field operations were completed in just seven days and executed safely and without a single incident, a testament to the OptiSeis' disciplined, safety-first approach to field execution.

Next-Generation, Low-Impact Technology

The survey showcased a modern acquisition design built around 1,355 autonomous nodal sensors deployed across the project area. Seismic energy was generated by an array of two IVI Minivibrators - a controlled, environmentally responsible energy source - and over the course of the program more than 2,700 seismic source points were recorded into the ground sensor array, generating a dense and detailed picture of the subsurface.

A Standout Scientific Collaboration

In conjunction with the surface program, a Vertical Seismic Profile (VSP) was acquired by Natural Resources Canada (NRCan). The VSP recorded seismic energy on fibre-optic cable installed within three centrally located wellbores - a unique opportunity to capture complementary datasets that may enhance subsurface characterization and contribute to ongoing geoscience research. This collaboration underscores the growing role of advanced, technology-driven methods in responsible resource exploration.

Field acquisition services were provided by Echo Seismic Ltd., a respected Calgary-based geophysical contractor selected for the project. A focused workforce of 11 personnel supported field operations, including two representatives from OptiSeis, with an additional two NRCan personnel onsite to support the VSP acquisition.

"This project demonstrates how modern seismic technology can support mineral exploration objectives while maintaining a very small surface footprint,"

"By combining autonomous modal sensors, low-impact vibrator energy sources, and existing roadway infrastructure, we were able to safely acquire high-quality subsurface imaging data while minimizing impacts on the local environment and surrounding community." Andrea Cook, Chief Executive Officer, OptiSeis Solutions Ltd.

Throughout the program, professional traffic control services were employed to support safe operations and minimize disruption to local residents. This operational practice reflects an OptiSeis commitment to being a responsible and respectful partner in the communities where it works.

Program Objectives

"This innovative 3-D seismic survey, which has been undertaken by industry leading geotechnical professionals at OptiSeis Solutions Ltd. under the auspices, and with the support. of Natural Resources Canada, is expected to result in direct actionable exploration targets for prospective MIAC and IOCG deposit types which may be identified proximal to the historical copper and gold mine workings along the McLaren Lake Fault Zone on Canuc's 100% owned East Sudbury Project," stated Christopher Berlet, President and CEO of Canuc.

"We will follow up promptly on the targets that result from this work, and also on those that result from our upcoming property-wide gravity gradiometric survey which covers all four (4) of the fault structures that transect the ESP property, in pursuit of a transformational regional exploration outcome."
