Mineral explorer Navigator Resources Ltd (ASX: NAV) said on Thursday that it is entering into a trading halt following the Wednesday announcement of a collapsed pit wall on the company's Bronzewing Gold Project, near Perth in Western Australia.

The company said that the collapsed occurred following several weeks of monitoring the Central Pit section though Navigator reported that nobody was hurt when the wall finally gave in.

Debris, however, from the collapsed wall were able to bury some ore reserves in the south-western corner of the open pit site as Navigator added that a major control drill rig was damaged during the incident, which could partially impact the site's ore output.

In its released statement, Navigator Resources gave assurance that the staged mining activities in the Central Pit would be able to restart operations within the next two days though it admitted that the site's "budgeted ore supply will be impacted in the short term."

Nonetheless, the mining company said that it is doing its best to maintain the current level of overall ore supply being delivered from the site's open pit and through the mill that processes the yields.

Navigator Resources said that in the absence of further advisories, its shares would remain in trading halt until September 27 next week. Navigator shares were trading at 22.5 cents prior to the announced trading halt.
