The Dome Mountain property includes the past producing mine.
December 13, 2023 Blue Lagoon Resources Inc. is pleased to provide an update on ongoing mine permitting and First Nation engagement on its Dome Mountain Gold Project.
After meeting various requirements, an initial ministry screening process was completed in July 2023 and the application was resubmitted for review shortly thereafter. Since then, two rounds of comments have been completed by the Ministry of Energy, Mines and Low Carbon Innovation (EMLI), the Ministry of Environment and Climate Change Strategy (ENV), and the Lake Babine Nation (LBN) and the Company and its technical consultants have responded to, and have completed, two rounds of responses and expect to resubmit the updated application on or before January 6, 2024 for further review and acceptance. |

Deposit Type
- Vein / narrow vein
- Orogenic
- Mesothermal
Summary:
The mineral deposits at Dome Mountain are structure-controlled orogenic (mesothermal) quartz-carbonate-sulphide veins with associated gold and silver mineralization. Controlling structures are east-west and northwest southeast trending brittle fault zones that dip moderately to steeply south and southwest. The host rocks are Lower to Middle Jurassic subaerial volcanic flows, pyroclastic, and related volcanoclastic rocks.
The most significant gold mineralization on the Dome Mountain Project is contained within five zones of the past-producing Boulder Vein System (listed in order of importance):
- Boulder Main Vein: This zone has a strike ranging from 090° to 100° and dips ranging from 45° to 70° south. The vein has been defined over a strike length of 440 metres from section 652,800 UTME to 653,240 UTME and a down-dip extent of more than 300 metres starting at the surface. The mineralized zone within the vein has a shallow easterly plunge with an average horizontal width of 2.4 metres, ranging from less than a meter to 21.2 metres. The majority of the 43,900 tonnes of past production came from this zone.
- Argillite Vein: The Argillite Vein is a splay off the Boulder Main Vein. It strikes at 120° and dips to the southwest at angles ranging from 35° to 50° and it appears to flatten along strike to the southeast. The zone is somewhat discontinuous over the defined strike length of 240 metres and a maximum down-dip extent of 90 metres. The miner ........
Mining Methods

- Mechanized Cut & Fill
- Longhole stoping
- Unconsolidated rockfill
Summary:
The Dome Mountain deposit is a system of structure-controlled orogenic (mesothermal) quartz-carbonate-sulphide veins with associated gold and silver mineralization. The mining method, mechanized ramp cut and fill, is contemplated being utilized at the Dome Mountain Mine to maximize recovery of the mineral resource. The mechanized cut and fill method optimizes mineral resource extraction since this method allows for the ability to follow irregular mineralized zones quite precisely and allow greater selectivity in mining and results in a higher-grade mineralized product. Recovery for this method was planned at 95% and dilution was estimated at less than 10%. Other mining methods that could be proposed in the future may include narrow vein long hole stopes in areas where the mineralized zone is dipping at more than 45 degrees, captive slusher stopes, shrinkage stopes, or resue mining to minimize dilution where the ore zone is too narrow.
Unconsolidated rock backfill is planned to be used in all mechanized ramp cut and fill stopes after mining is completed to stabilize the ground and to provide a working platform for the next cut and fill lift (stope). This backfill is the development waste from the Dome Mountain Mine. This will reduce the overall closure costs for the operation. It is planned to carry out geotechnical studies in the future to determine if cemented rock fill (CRF) is an option for backfill. This is also depended on future permitting requirements.
