This is the type of agreement we shld be seeing. PDN bond issue. Tier 1 U308., page-55

It's an extension to a 'notice of deficiencies' letter. So basically the state authority had some issues with the borehole trial that they wanted sorted out and BLR couldn't do it within the 30 days allowed. Most likely because they didn't have the funds or resources while the T/O was being processed.

Given the T/O won't be voted on before this extension expires, it would actually make sense for BLR to simply withdraw the application and deal with it after the shareholder vote when it's known if and when the trial could take place.
