Salares Norte The critical path of the project remains on track , although Q3 2021 was again impacted by severe winter weather ( in the early part of the quarter ) as well as ongoing COVID - 19 constraints . Given the COVID - 19 and weather impacts it is unlikely that the project will achieve the previously guided 65 % completion milestone by the end of 2021 and should see completion of around 62 % by year end . Importantly , all the critical path items are tracking plan . In addition , more than 95 % of imported components have arrived in Chile , so the project is not expected to be delayed by shipping constraints currently being experienced globally . The project remains on track to deliver first gold by the end of Q1 2023. Mining and exploration were the standouts for the quarter , with both activities outperforming the plan for the quarter .
