    "Water shortages are starting to threaten copper production in a country that accounts for more than a quarter of global supply.
    [Blockierte Grafik: https://servedbyadbutler.com/error/blank.gif]
    In Chile this week, a BHP Group mine was ordered to halt groundwater pumping for three months, while Antofagasta Plc warned it will produce less than expected this year amid water supply constraints.

    While BHP’s Cerro Colorado is a small operation coming to the end of its life and Antofagasta’s guidance cut isn’t huge, the disruptions underscore the challenges of running mines in one of the world’s driest deserts. Copper mines have been pumping water out from aquifers under the soil for decades, often to the detriment of local communities.

    The issue has risen to prominence recently as the desert expands south amid a decade-long drought, potentially exacerbated by global warming. The industry has responded by stepping up efforts to switch to seawater, which is expected to account for almost half of its total water consumption by 2031.


    Chile is now drafting a new constitution in the wake of mass protests against social injustices, with lawmakers pushing for reforms to a water system that has relied heavily on private enterprise and market forces to allocate rights and deliver services .




    In that context, an environmental court took the surprising step of blocking, albeit temporarily, Cerro Colorado’s use of water from the Lagunillas aquifer starting on Oct. 1 as it hears a lawsuit that accuses the operation of environmental damage.


    The company said it would “evaluate the courses of action based on instruments that the legal framework provides and will take operational actions to comply with the measures that are available.”


    The smallest of BHP’s three copper mines in Chile has faced opposition from local communities over its use of underground water. Last year, it announced plans to scale back operations, effectively bringing forward a programmed downsizing ahead of the 2023 expiry of its permits. At the time, the company said it would continue to explore options to extend mining beyond 2023 by using seawater.


    Antofagasta now expects to produce 710,000 tons to 740,000 tons of copper this year, down from its previous forecast of 730,000 tons to 760,000 tons. The Santiago-based company is building a desalination plant, but that won’t come into operation until the second half of 2022, putting at risk another 50,000 tons of copper production next year.


    “This year has been the driest of a 12-year drought in Chile,” Antofagasta said in a statement Thursday. “Given the traditional rainy season runs from June to September, it is looking increasingly likely that the low levels of precipitation will continue until at least the Southern Hemisphere winter next year .”

    Marimaca Copper Corp, One of the most important copper discoveries in Chile over the last decade

    "Chile-focused explorer Marimaca Copper holds the distinction of making one of a handful of (or perhaps the only) new copper discoveries around the world since 2015. While this paucity of new discoveries speaks to a growing problem in the balance of supply and demand for the dynamic ‘red metal’, Marimaca’s namesake project was unearthed in 2016 by the TSX-listed company’s VP of exploration, Sergio Rivera, when a one-in-a hundred-year rainfall washed away decades of Atacama dust to reveal a green hue on a mountain side in an area of Chile’s prolific copper mining centre in Antofagasta. Having said that, the Marimaca deposit was not completely unknown prior to the rare weather event; there was outcropping mineralisation at surface that had been walked over and identified by numerous geologists, but generally accepted wisdom for the area dictated that there would be nothing new to uncover of sufficient scale for a mine. “I think it’s been a story of challenging the generally accepted wisdom about what sort of copper project could be in the belt of rocks we have there in Northern Chile,” says Marimaca’s president and CEO Hayden Locke.


    “Our geologists challenged that wisdom and decided it was worth drilling. What they found was significant extensions North and South along strike and also at depth. As a result, it is one of the most significant new oxide discoveries in Chile in the last decade and certainly one of the most exciting development stage copper projects in the world today. It also has a very short timeline to get into production in what is a fantastic copper environment for us.


    “Marimaca’s discovery of a surface oxide copper deposit with significant depth potential not only contradicts the once-held views of many experts in the field, it also creates a low-risk, low-cost mine development scenario for the company.


    “It is quite a unique project in that there is oxide mineralisation at surface, a low strip ratio for an open pit mine with very low capex relative to most of the new copper development stories in the world. We’re excited to have this project in our control.”


    Location, location, location


    The location of the deposit is a huge part of Marimaca’s attractive story, according to Locke, who cut his teeth mostly developing projects in African mining jurisdictions, where infrastructure has been at times poor, and mine locations often remote.


    Good locations have existing infrastructure in place and access to a highly skilled workforce; things which have a knock-on impact in terms of execution risk and capital costs. “The location we have at Marimaca is absolutely outstanding,” Locke proclaims.


    “We’re in the low coastal range of the Chilean mountain range, so fairly low altitude compared to being in the high Andes. We have access to power, roads and communication is incredible. There’s an international airport 45 km away, we have a very large, highly skilled workforce that is generally working in the mining industry or some derivative of it.


    “All of that adds up to much lower execution risk, but also much lower capital cost for the overall project. It [the location] is a huge benefit for us and one that we are very happy with.” He highlights access to water – a key input in the copper mining process, but a scant resource in one of the most arid parts of the world – as the single biggest locational advantage.


    Marimaca will use seawater at its operation, which crucially means it won’t have to tap into local freshwater aquifers that are vital for drinking, agriculture and the general environment. From an ESG standpoint, this is absolutely essential to the project’s successful development in a region where political and social objections have blocked the progress of mining projects in very recent memory.


    Publishing the PEA


    The low upfront and all-in sustaining costs (AISC) nature of the Marimaca project was confirmed by the August 2020 preliminary economic assessment (PEA). The study calculated the upfront capital cost at US$285 million, while the AISC of $1.29 per pound of copper is in the bottom 15% of the curve.


    Hayden explains that the low-cost nature of the project comes down to three key attributes: “First, it’s a very simple open pit mine. As a result, there is virtually no pre-strip, very little up front capital costs to get this project into mining and start taking valuable ore and putting it on the leach pads.”


    The presence of a high-grade core in the first five years of mining is an added advantage which means the company can move lower material tonnes and hence use a smaller fleet of equipment during the first stage.


    The second low-cost attribute is the ability to use SX-EW leaching as the process method. On a per tonne of copper produced basis, the capital intensity for an SX-EW plant is much lower than a concentrator, notes Locke.


    Locational advantage, predominantly Marimaca’s access to a power line 7 km away, is the third contributor to the low-cost project estimates. Roads and the seawater pipeline are already in place and there is no need for a mining camp as there are two urban centres (Antofagasta and Mejillones) within 45 km of the site.


    The PEA also calculated a post-tax NPV of $524 million for the project (assuming a $3.15 per pound flat long-term copper price) and an IRR of 33.5%, with annual copper production at approximately 40,000 tonnes in the first six years, over a total 12-year life.


    Marimaca actually went above and beyond with certain elements inside the PEA advanced to an even higher degree of confidence. For instance, the metallurgical recoveries are supported by four phases of testing.


    “The fifth phase is really about making sure we are completely bankable, but also preparing ourselves for operational readiness and making sure we have a really robust geo-metallurgical model,” Locke declares.


    A round of infill drilling will also be required to shift the remaining 30% of the Marimaca resource from inferred to measured and indicated (M&I). The project currently contains nearly 420,000 tonnes of contained copper in M&I, according to a December 2019 mineral resource estimate.


    “We’ll probably do a bit more extensional drilling to add some more to the overall resource ahead of the feasibility study, which we’ll hopefully start in the second half of this year with the goal to deliver that in the early part of next year.”


    Lifting the lid further


    Marimaca is also pursuing a dual-track exploration strategy after identifying the potential to add resources at depth and across the coastal copper belt district. While the company has reported good visibility on a couple of years of oxide resource around Marimaca, it is focusing its near-mine exploration on the potential at depth......................................................................."

    Marimaca Makes New Shallow Oxide Copper Discovery at Mercedes





    Vancouver, British Columbia, September 8, 2021 – Marimaca Copper Corp. (“Marimaca Copper” or the “Company”)
    (TSX: MARI)     is pleased to announce that reverse circulation (“RC”) drilling completed at the Mercedes Target (“Mercedes”), has intersected significant oxide copper mineralization from surface, with an initial area of interest measuring 400m along strike and 300m width. A total of 17 holes were completed of which 12 intersected mineralization. Mercedes is located less than 1km to the north of the northern edge of the Marimaca Oxide Deposit (“MOD”) and offers clear potential to add to the Company’s leachable resource base.
    Highlights

    • Broad zones of near surface oxide copper mineralization intersected in eight holes:

      • MER-12 intersected 86m with an average grade of 0.44% CuT from 6m including 42m @ 0.64% CuT
      • MER-16 intersected 48m with an average grade of 0.42% CuT from 20m including 20m @ 0.57% CuT
      • MER-06 intersected:

        • 74m with an average grade of 0.30% CuT from 18m including 46m @ 0.38% CuT; and
        • 18m with an average grade of 0.52% CuT from 132m.
      • MER-14 intersected 26m with an average grade of 0.42% CuT from 80m including 12m @ 0.69% CuT
      • MER-03 intersected 58m with an average grade of 0.34% CuT as part of a broader 98m @ 0.30% CuT from 4m
      • MER-04 intersected 36m with an averaged grade of 0.34% CuT as part of a broader 86m @ 0.26% CuT from 6m
      • MER-17 intersected 50m with an average grade of 0.25% CuT from 2m
      • MER-01 intersected 28m with an average grade of 0.21% CuT from 4m
    • Underground mapping of historical workings indicates continuous zones of higher-grade mineralization than encountered in the first phase of drilling
    • The current drilled area of interest extends 400m along strike and 300m east-west and remains open to south and east
    • Weak or thinner mineralization was intersected in MER-02, 05, 09, 13, 15 and no significant mineralization intersected in holes MER-07, 08, 10 and 11

    Sergio Rivera, VP Exploration of Marimaca Copper, commented:
    “We are very pleased with the results from the discovery drilling campaign at Mercedes, which has identified significant shallow oxide copper mineralization less than one kilometre away from the flagship Marimaca oxide deposit. The mineralization consists of broad zones of predominantly green oxides, commencing at surface, with some mixed, enriched and copper wad sections.
    “The structural controls observed at Mercedes are very similar to the MOD and we note that the higher-grade materials appear to be spatially related to the presence of dacitic dykes, which become more prevalent to the east of the currently drilled area.
    “Mercedes remains open to the east and to the south, where it is within 1km of the northern extent of the MOD. We are examining whether Mercedes and the MOD may be part of a larger mineralizing system and plan further exploration accordingly.”

    Hayden Locke, President and CEO, of Marimaca Copper, commented:
    “We have now drilled two conceptual exploration targets and identified significant shallow, oxide, copper mineralization in both. We have several other targets close to the MOD that have yet to be drilled, and we take great encouragement from the success at both Cindy and Mercedes. We own the entire land position, which we believe is prospective for Marimaca style mineralization, and this will allow any shallow oxide discoveries to form part of our future development plans and add value to what is already a project with compelling economics.”
    Overview of Drilling Campaign Objectives and Results
    The initial drilling campaign at Mercedes (located less than 1km to the north of the northern edge of the MOD) consisted of nine shallow, RC drill holes targeting the anomalies identified in both the magnetic survey and surface geochemical sampling previously completed (refer to announcements on 23 September 2020 and 17 February 2021 respectively). Based on the results of the first nine holes, the program was extended to seventeen holes across approximately 700m of north-south strike. The objective was to identify new, broad zones of shallow oxide mineralization that could complement the existing resources at the MOD.

    Figure 1: Plan view of Selected Drill Holes at Mercedes

    The seventeen holes were drilled at various orientations over an area of approximately 700m by 300m, and eight encountered notable oxide copper mineralization. Drill holes MER-03, MER-04, MER-06, MER-12, MER-16 and MER-17 in particular, intersected broad zones (approximately 50m downhole or more) of oxide copper mineralization commencing near surface. These drill holes define an approximate area of interest for follow up drilling extending 400m north-south and 300m east-west.
    MER-12, located on the northern limb of the area of interest, was an especially positive drill hole, intersecting 86m with an average grade of 0.44% CuT from 6m, including a higher-grade zone of 42m at 0.64% CuT. As at the MOD, this mineralization is structurally controlled by pervasive east dipping fractures in the host monzodiorite and consists of dominant atacamite-brochantite and chrysocolla with increasing copper wad material in the deeper intersections.
    In addition to drilling, the Company has completed extensive mapping and sampling of the small scale historical underground workings at Mercedes. The results from this work highlights the extensive and continuous nature of the mineralization with broad zones of copper oxide. The underground workings were sampled continuously over 434m with an average grade of 0.49% CuT over this length and encompassing several higher-grade zones, including 66m at 0.80% CuT, 60m at 0.70% CuT, and 20m at 1.55% CuT. The copper minerals were the same as those observed in the drilling program.

    Figure 2: Plan view of Mercedes and Selected Results of Underground Mapping and Channel Sampling

    Mercedes is structurally controlled by a pervasive sheeted fracturing of the intrusive host, which dips to the east at between 45 and 60 degrees. Similar to the MOD, there is zonation of mineralization trending from more dominant green oxides at the top of the intersections to more mixed and copper wad types at the peripheries and towards the bottom of the intersections.

    Figure 4: Cross Section EW 7,437,600 (Drill holes MER-12 and MER-14)

    Overview of Mercedes
    Mercedes is located less than 1km from the northern edge of the MOD. It was identified initially through the results of the high-resolution drone-mounted magnetic survey (refer to release on 23 September 2020), which was followed up by reconnaissance mapping and geochemical sampling (refer to release on 9 December 2020).
    Mercedes is hosted in the same intrusive units as the MOD, which shows pervasive fracturing striking north to south with an easterly dip of between 45 and 60 degrees. The unit is cross-cut by various dykes and faults, all of which are important for the development of copper mineralization.

    Figure 5: Map of MOD Resource and Near MOD Exploration Targets    Mercedes is the second of three new exploration targets drilled by the Company within a radius of 5km around the MOD, each of which presents a compelling opportunity to add shallow, oxide resources to the MOD project...
