Quebec Innovative Materials Corp. (QIMC) said on 20 October it would add a 26.8-kilometre east-west Line 5 across the Ontario portion of the Témiscamingue Graben to its seismic programme. Combined with its 36-kilometre Québec programme, the company plans approximately 63 kilometres of cross-border coverage.

QIMC said it selected a corridor where its surveys recorded the Ontario graben’s highest soil-gas hydrogen concentrations to date. Echo Seismic is to acquire the data and Earth Signal Processing is to process them. This is planned vibroseismic surveying; it is not evidence of a hydrogen accumulation or a production announcement.

## Data

### Announced seismic coverage

Seismic line lengths and coverage QIMC describes as completed or planned.

Methodology: The release describes survey campaigns and line lengths. The Ontario line is planned acquisition, not a hydrogen discovery. Approximate totals retain that qualifier. Rows contain both components and totals that include them; do not sum all rows.

| Programme / component | Length (km) |
|---|---|
| Ontario Line 5 (planned) | 26.8 |
| Québec Témiscamingue seismic program | 36 |
| Québec–Ontario combined coverage (approximate) | 63 |
| Nova Scotia acquisition completed | 63.7 |
| QIMC coverage across three provinces, completed and planned (approximate) | 126.5 |
