It looks to me like the interest rates started an up wave in August, and at the same time, Gold started a down leg since August. What else could it be? Look at the charts.
Gold $2010 high $1800 today is 10.44% Lower
Gold: https://finance.yahoo.com/quote/GC=F?p=GC=F&.tsrc=fin-srch
Rates: 1.29% interest up from .53% rates, a whopping 140% higher since August.

Considering the rates are 140% higher, and Gold is only 10.44% lower, the scum is shooting rubber bullets.
