During construction of Constancia Copper summer winter spring didn't matter. Yes snow on ground hundreds of tons of steel were erected and huge ball & SAG Mills, conveyors the lot.
I suppose schedule and funding depended on construction continuing.
I would say at least days are longer in summer months temperatures more bearable but the location is logistically challenging any weather.
The INCA people don't know any different. That project we slept at 4200 the top of the deposit was 4600 meters.
We are similar to that height.
Once assays are in and maybe overlay 3D the rock science boys will have to pin a pin to where the drill goes. Hopefully this year.
