Lifecycle Milestones

1. Permit granted

   Jan 2015 · Spain's resolution granting the global Mining Permit for the Riotinto Copper Project (including approval of the Restoration Plan) was signed January 23, 2015 -- per the company's own reporting, the last significant regulatory approval needed before normal mining/processing could commence at this restart of the historic Rio Tinto mine (closed 2001, acquired by EMED Mining/Tartessus in 2008, rebranded Atalaya Mining 2015). · Source
2. Construction decision (FID)

   Reached — date not disclosed · Approval of the 15 Mtpa expansion at Riotinto, December 2017 -- Atalaya's own words on its Riotinto 15 Mtpa Plant page: 'In December 2017, Atalaya approved an expansion that would increase Riotinto's throughput capacity from 9.5 Mtpa to 15 Mtpa.' Approximately EUR80.4m capex, funded by a ~GBP31m equity raise the same month; the company's own history page lists it as 'Approval of 15 Mtpa expansion at Riotinto'. Month/year precision only -- no exact day found in any source -- so achievedDate stays null per the Task #610 convention (a null date does not weaken the row; ~130 genuinely-satisfied milestone rows DB-wide carry one). SCOPE CAVEAT, disclosed: this is a BROWNFIELD PLANT-EXPANSION approval, not the decision that restarted Riotinto. There is no restart FID and there cannot be one -- EMED Mining (Atalaya's predecessor) acquired the mothballed historic Riotinto mine out of its insolvent predecessor's estate in October 2008 via EMED Tartessus SL, and what followed was a seven-year PERMITTING fight, not a study-then-FID sequence. Atalaya's own history page jumps straight from 'January 2015 - Final permits for Riotinto obtained' to 'July 2015 - First concentrate', with no restart-decision entry between them, and the major GBP64.9m placing was announced 28 May 2015 -- AFTER the 17 Apr 2015 first blast. This row therefore postdates FIRST_PRODUCTION (Jul 2015); see the header. A second real approval also exists and is recorded here for the next pass rather than lost: 'Approval of E-LIX Phase I plant construction', January 2022 (month precision, same page). · Source
3. Construction start

   Apr 2015 · First blast at the restarted Riotinto mine was performed on April 17, 2015, shortly after the January 2015 permit. · Source
4. First pour / production

   Reached — date not disclosed · Per Atalaya's own history page, first concentrate production at Riotinto was achieved in July 2015 (commercial production was formally declared later, Feb 1, 2016 -- a separate, later milestone). Exact day within July 2015 not given. · Source
5. Commercial production

   Feb 2016 · Genuinely reached with a clean, single, well-documented date: Atalaya Mining's Proyecto Riotinto (Cerro Colorado open pit, within the historic Riotinto mining district, Huelva, Spain) entered commercial production on 2016-02-01, after successfully completing commissioning and ramp-up of Phase I, well ahead of the company's original Q3 2015 schedule and under budget. Cerro Colorado/Riotinto remains Atalaya's flagship and effectively sole major producing asset -- Touro (Galicia) is a separate, non-producing development project. This row was missing entirely prior to 2026-08-21 -- a genuine data gap, not a stage error; Miner.stage was already correctly PRODUCTION. · Source

Milestones are recorded only from a company's own dated disclosure. A milestone with no date shown is one we can confirm was reached but for which no date was disclosed — we don't estimate one. "Not yet reached" means exactly that, not that a date is missing. An "Expected" line likewise only ever reflects the company's own guidance (e.g. a study or permit decision targeted for a stated quarter) — most not-yet-reached milestones have none, and that absence means no such guidance has been disclosed, not that one is overdue.

A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal the underlying research identifies — whether a major already holds a JV, earn-in, or 5–19.9% strategic stake — isn't tracked yet and is absent from this score.
