Hi,
Since your post nothing has happened. Their project updates just show superficial excavation. That too, many boulders are visible, indicating the possibility of hard rocks beneath. With this pace, I doubt if they could even complete the excavation by august unless they go for blasting. But here they may require additional approvals and presumably they have held up the machine excavation and could be waiting for approvals from govt. authorities, probably from Controller of explosives.
All are my wild guess. Any one visited the site and have right information may please update.
Thanks in advance.
Regards,
TW
