Looking at the chart below, we can see Mexico’s silver production declined 58 metric tons (mt), from 484 in April last year down to 426 metric tons in 2015:

That’s a large decline in just one month. Mexico’s total silver production for the first four months of 2015 is down 5% (92 mt) compared to last year.

No reason for the decline. I suppose it's possible they could ramp it back up if the price of silver (and copper?) rose (and made it attractive to do so).
It will be interesting to see if record sales of physical silver ever do reach that tipping point of exhausting physical supply.
