• Maiden drilling program starts with 5 holes planned for 450m
• High priority drill targets include old mine workings and outcrop containing
high grade gold and cobalt mineralisation
Azure Minerals Limited (ASX: AZS) (“Azure” or “the Company”) is pleased to advise that diamond drilling of the first hole of a five-hole program has started on its 100%-owned Sara Alicia goldcobalt project, located in the northern Mexican state of Sonora (see Figure 1).
High grade gold and cobalt mineralisation was historically exploited by small-scale underground mining in the 1930s. Azure’s first-pass sampling of surface and underground exposures confirmed the presence of this mineralised zone, returning high grades of gold and cobalt up to maximum values of 39g/t gold and 7% cobalt (see Photo 1 and refer ASX announcement of 23 August).
A reconnaissance drill program has been designed to test this zone with an initial five holes totalling approximately 450m of diamond core planned (see Figure 2 for hole locations). A followup drill program may be undertaken, depending upon initial results.



All approvals granted for diamond drilling at Oposura and Sara Alicia
• Drilling expected to start on both projects within a week
• Two drill rigs at Oposura will enable resource estimation in early 2018
• Sara Alicia drilling to test high-grade gold-cobalt mineralisation
Azure Minerals Limited (ASX: AZS) (Azure or the Company) is pleased to advise that it is about to start drilling campaigns on both its new flagship Oposura zinc-lead-silver and the highlyprospective Sara Alicia gold-cobalt projects in the northern Mexican state of Sonora. The projects, both recently added to Azure’s Mexican portfolio, have received all required approvals from the environmental authorities and drilling is expected to start within a week.

Azure Minerals Limited (ASX: AZS) (“Azure” or “the Company”) is pleased to announce that it has further broadened and strengthened its Mexican exploration portfolio with the purchase of the Sara Alicia goldcobalt project, located in the northern state of Sonora.
Azure Managing Director Mr Tony Rovira also commented, “During Azure’s recent search for an advanced stage precious metal / base metal project, which culminated in the recently announced acquisition of the Oposura Project, the Company identified many early stage properties with good potential. One of the absolute stand-outs was the Sara Alicia gold-cobalt project.
“Cobalt deposits are virtually unknown in Mexico, which makes the identification by our exploration team of a property containing high-grade gold and cobalt mineralisation very commendable. This was an opportunity too good to pass up and its acquisition has added an extra dimension to our Company’s project portfolio.
“Spectacular grades returned from our first sampling program indicate that this under-explored property holds potential for the definition of a body of high grade gold-cobalt mineralisation, as well as for copperzinc-silver mineralisation. We look forward to drilling Sara Alicia this year, along with progressing our flagship project Oposura.”

Highlights on the Second Week of January, 2017. Mineral Exploration in Mexico

During the 2nd week of the year (9th to 15th January, 2017) at least 31 press releases were announced by companies working in Mexico, including ten preliminary production reports for 2016. ON EXPLORATION, nine companies presented exploration updates, reflecting fairly strong activity in this new year. A company completed soil surveys in a project in Sinaloa, and another in Sonora. Also in Sonora, a project generator presented 2016 results and presented plans for the year, while a mining company released high grade gold drilling results on its brownfield and mine site exploration. In Zacatecas, results from surface exploration were received in one project, while another property received the needed drilling permit. On Nayarit, three more holes have been completed in a property. Anomalous but still interesting drilling results were received for a project in Guerrero. In Chihuahua, results from underground channel sampling in a silver project were released, whereas in Oaxaca, a polymetallic vein system continues to expand, showing high grade drill intercepts on a 200 m step out. ON MINING, Torex Gold, US Antimony, Endeavour Silver, HECLA Mining, Great Panther, Fortuna Silver, Timmins Gold, Capstone, Premier Gold, Pan American Silver, and Gold Resource presented 2016 production figures. A company presented the 2016 production figures, and plans for the coming years in a copper mine in Baja California Sur.  ON FINANCING, Two companies reported financing exercises for a total of $16.4 M in gross proceeds. ON RESOURCES, one company filed NI-43-101 reports for two projects in Sonora and Nayarit. ON DEALS AND CORPORATE ISSUES, an agreement on the sale of one of the major gold operations in Mexico has been completed. An agreement on the option of a past producing mine in Guanajuato was achieved between a junior Canadian company and a local Mexican enterprise.

Sediment–Hosted Copper Deposits

Sediment-Hosted Copper deposits (SHCD) occur within sedimentary basins, generally at the contact between subaerial red-bed sequences and overlying marine or lacustrine shales, siltstones, sandstones, or carbonate rocks (Kirkham, 1989), consisting of relatively thin (generally <30 m and commonly < 3 m) sulfide-bearing zones from moderate-temperature (50°-150°C), moderate to high salinity (from 7 to + 30 eq. wt % NaCl), oxidized fluids (hematite-buffered) at oxidation-reduction interfaces (REDOX fronts). These deposits appear in a variety of sedimentary rocks with a variety of reductants. The configuration of the mineralized zone ranges from sheet like, with extensive horizontal dimensions, to tabular or roll-front geometries, with limited horizontal dimensions (Kirkham, 1989).

Approximate synonymous for SHCD are Diagenetic Sedimentary Copper, Red-Bed Copper, Stratiform Copper, Kupferschiefer type, Sandstone Copper, Shale-Hosted Copper, Reduced facies Copper, Sabkha Copper, and Revett Copper.

Sediment Hosted Copper Deposits are valuable because:

  • They are the second most important source of copper worldwide after Porphyry Copper deposits.
  • The world most importance source of cobalt (60%)
  • Important producer of by-product silver
  • SHCD contains consistent grades and lateral continuity along bedding (1.2 to 5% Cu), and
  • SHCD may contain large resources of by-product Au, U, platinum-group, and rare-earth elements.

Some of the most common features of the SHCD are:

  • They are stratabound.
  • Restricted to a narrow range of layers within a sedimentary sequence but do not necessarily follow sedimentary bedding.
  • Epigenetic and diagenetic, that is, they are formed after the host sediment is deposited, but in most cases, prior to lithification of the host.
  • They form independently of igneous processes.
  • Uniform lateral continuity of mineralization along bedding.
  • A major thickness of permeable, coarse-grained, red-bed clastic sediments in the immediate footwall of the cupriferous zone.
  • Temporal and spatial association of host rocks with strata formed in warm arid climates (evaporitic units, red-beds).
  • Deposition of Cu from aqueous, chloride-rich solutions upon crossing the redox front between footwall red beds and reduced, sulphide-bearing grey beds of the host strata
  • Associated with rift basins filled with continental red-beds+-bimodal volcanic strata.
  • Deposits are normally closely associated with evaporite sequences which provide an oxidizing environment, source for large sulfur volumes, and high salinity brines for metal transport.
  • Mineralization normally is associated with the presence of reduced, high-organic sedimentary units above and / or lateral to oxidized red-bed sequences. Oxidized units are hematite-bearing with the notable absence of iron sulphides. Oxidized units normally contain a high permeability prior to and often after mineralization.
  • Zoning, where recognized, is commonly from hematite-rich, sulfide barren zones to chalcocite-bornite-chalcopyrite-pyrite zones. It is interpreted as the basin-ward precipitation of ore fluids.

 Genetic implications for SHCD are:

  • There must be an oxidized source rock.
  • There must be a brine source to mobilize copper.
  • There must be a source of reduced fluid to precipitate copper and form a deposit.
  • There have to be conditions favourable for fluid mixing.

Although there are multiple occurrences of SHCD worldwide, the supergiant deposits are present in only three basins: the Paleoproterozoic Kodaro-Udokan basin of Siberia, the Neoproterozoic Katangan basin (Central African Copperbelt), and the Permian Zechstein basin of northern Europe (Hitzman et al, 2010).
