RE:> 200,000 ounces of gold production from Segovia in 2021 the news release partly answers your question
"announced today that it expects to produce between 200,000 and 220,000 ounces of gold in 2021 from its high-grade Segovia Operations in Antioquia, Colombia. In 2020, the Segovia Operations produced 196,362 ounces of gold."
segovia guidance for 2021 is for an increase in oz from 2020. that should be good.
marmato produces around 25k oz per year which will be expanding to 50k oz soon.
your 240k number was a peak when they mined a higher than normal grade area at providencia.
200k-220k segovia + 50k marmato would have looked good in news release of 250k-270k oz total production, but since ownership of marmato went below 50% they don't include marmato anymore.
however, gcm counting segovia only will have a lot lower aisc number because the marmato aisc was very high and pulling up the average aisc. all of gcm earning was from segovia anyway. marmato small operation in the past was losing money to break even.
their 4th mine carla has very high grade at depth from exploration results, so should gradually add to oz.
a lot of exploration drilling of their other 24 veins this year means a lot of room to expand production.
