"Colombia has elected a new President, Gustavo Petro, its first leftist president, who promised sweeping reforms that would affect the energy, mining, and pensions sectors. Historically, the country has been very welcoming to mining, and it's been one of the better jurisdictions in South America. However, Petro has noted that he would ban open-pit mining, and tighten regulations. The good news is that this doesn't affect many companies, given that the main mines in Colombia are Marmato (Aris Gold), Segovia (GCM Mining), and Buritica (once owned by Continental Gold, and now owned by ZIjin). These are underground mines, and they're already in production, so I wouldn't; expect them to be affected greatly, though I certainly wouldn't want to own a single or dual-asset asset producer in Colombia following the election until it's clear if there will be major changes.
Among non-producing assets, B2Gold and AngloGold had planned to develop Gramalote, and that looks like it will be shelved, with it expected to be a massive open-pit mine and it was B2Gold's main area of growth, as well as a key one for AngloGold. This could explain why B2Gold recently acquired Oklo in Mali near its Fekola Mine and has been ramping up exploration north of its Fekola Mine in the Anaconda area, with the hope to build a new Mali mining complex (capable of 900,000+ ounces per annum vs. 550,000 currently).
Unfortunately, AngloGold Ashanti also has Quebradona, a development project (gold-copper-silver) so the news is especially unfavorable for them, affecting two of their development projects. I don't expect this to be a huge issue for AngloGold as its application already had run into hurdles (suggesting limited value was being applied to the project by the market), but the loss of Gramalote is a bigger hit, and this has taken a bite out of AngloGold's growth potential and its large development pipeline."
