(Reuters] -Newmont Corp posted a drop in profit for the first quarter of 2017. The lower volume of gold sales caused by lower prices has led to a decrease in profits.

Since the Omicron coronavirus variant’s emergence, miners have had to deal with movement restrictions and labor disruptions.

Newmont, in February, warned Omicron-related issues could have an impact on its gold production. This warning was made by Newmont.

Based in Denver, Colorado, the company reported that its quarterly attributable gold production fell by 8%.

From $1,039 last year, its all-in gold sustaining cost, an industry measure that measures production costs, increased to $1.156 per ounce.

In the third quarter, net income from stockholders derived from continued operations dropped to $432million (54 cents per shares) from $538million or 67 cents per shared a year prior.

Newmont also had to pay $17 Million in COVID-related expenses.
