Solis Bolsters Copper Landholding in Peru

May 09, 2024 9:00 AM EDT | Source: Solis Minerals Ltd.

HIGHLIGHTS

  • New applications cover 6,400 hectares of highly prospective copper ground across a coastal belt located directly between Ilo Norte and Ilo Este

  • Areas were previously held by Anaconda Copper. Ground visits indicate the area has received limited exploration

  • Total of 43,500 hectares pegged, mostly in the coastal belt, establishing Solis as a significant landholder in a highly prospective and emerging belt with porphyry copper potential

  • Two drill permit applications now underway over Ilo Este and Ilo Norte (Chancho al Palo). Cinto application in planning phase

  • Copper mineralisation in association with silicification and alteration identified outcropping at surface on new application areas

  • Follow-up mapping and initial geophysical studies to commence immediately

  • Solis continues to review potential acquisitions in various jurisdictions and commodity spaces with a focus on copper and lithium projects which are drill ready or with mineralised systems already identified

West Leederville, Western Australia--(Newsfile Corp. - May 9, 2024) - Solis Minerals Limited (ASX: SLM) ("Solis" or the "Company") is pleased to announce an update on recent applications for new copper exploration licences in Peru. Solis has successfully applied for a 6,400-hectare package comprising of seven licences of largely underexplored exploration areas in a highly prospective coastal belt, which were pegged on the 2nd of May (see Figure1). The areas were previously held by Anaconda Copper. Field visits by Solis teams indicate minimal ground exploration has been carried out in recent times.

The Company now holds a significant landholding of 43,500 hectares principally along a coastal belt bounded to the west by batholiths of Jurassic and Cretaceous age (see Figure 2). Based on the outcropping porphyry copper mineralisation at Ilo Este, Solis considers that the eastern margins of the batholiths represent highly prospective areas for porphyry copper occurrences emplaced in volcanic or volcaniclastic rocks.

Executive Director, Matthew Boyes, commented: "We are very pleased to further bolster our portfolio through the addition of a large land package containing highly prospective copper exploration ground in Peru. Solis is building a compelling portfolio of exploration properties in an underexplored porphyry belt, with excellent access and existing infrastructure. Drill permits are advancing as quickly as possible in conjunction with our ongoing non-invasive exploration efforts, preparing us to commence drilling once all necessary approvals are obtained and first drill sites are finalised.

"Solis continues to review and progress potential acquisitions in the copper and lithium space across targeted areas of South America and has two teams dedicated to the evaluation process, which is now bearing significant fruit. In the next 6-12 months will see advancements across our pipeline of copper exploration projects in Peru as we continue to look to add to our Brazilian portfolio of lithium properties."

1The presence copper oxide samples indicates a mineral species only and should not be considered a substitute for analytical results. Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analysis where concentrations or grades are the factor of primary economic interest.

The mapping crews are now mobilising to site to systematically cover the entire tenement package and identify areas of highest prospectivity. Low-cost drone magnetic studies in conjunction with remote sensing data interpretation will be carried out and followed up with Induced Polarisation (IP) studies over areas of interest to identify and evaluate primary drill targets.

Drill permitting

Both Ilo Este and Ilo Norte have been recently covered by magnetic and IP surveys that have identified drill targets and drill permitting to test these targets is underway.

Community engagement has commenced at Cinto as part of the process to advance the drill permitting over the project area. Cinto is located 15km SE of the major Toquepala Cu porphyry deposit in northern Tacna which has seen many benefits from the mining canon associated with existing mines.

CriteriaJORC Code explanationCommentary
Sampling techniques

  • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

  • Include reference to measures taken to ensure sample representativity and the appropriate calibration of any measurement tools or systems used.

  • Aspects of the determination of mineralisation that are Material to the Public Report.

In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.

  • Rock chip and grab samples were taken from outcrop which exhibited visible copper oxide mineralisation, the samples are considered to be as representative as possible of the outcropping although they are grab samples and not representative of the body of mineralisation as a whole.

  • Chanco al Palo Induced Polarisation survey (IP).. Equipment used are: Receptor RX,GDD/ Model GRx8-32-16ch; Transmitter TX 11, model Walcer KW 10; and Generator model 01 Honda EG6500CX 24 HP. Acquisition parameters:

Orientation of data in relation to geological structure
  • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
  • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.

  • No drilling data is reported in this announcement all historic drill holes have been designed at all times to cut the orientation of interpreted and mapped outcropping mineralisation perpendicular to strike of the interpreted structures as to accurately as possible estimate the true width of the target bodies.

  • No bias has been introduced in current drilling and sampling

Sample security
  • The measures taken to ensure sample security.
  • All samples are bagged onsite under supervision of Solis staff, all bags are then sealed and couriered to the relevant laboratories with all relevant submission documentation.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section)

CriteriaJORC Code explanationCommentary
Mineral tenement and land tenure status

  • Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.

  • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

  • All mineral tenure in Peru is currently in good standing a full table of tenements currently under application and which have been granted is included in this release as APPENDIX 1 "Mining concessions table"
Exploration done by other parties
  • Acknowledgment and appraisal of exploration by other parties.

Minimal historical exploration is believed to have occurred on the recent applications referred to in the announcement.
Geology
  • Deposit type, geological setting and style of mineralisation.

  • Prospective potential mineralisation is interpreted to be hosted along the eastern margin of the coastal Cretaceous batholith, porphyry style mineralisation has the potential to form along this major regional trend

  • Peru- Prospective potential IOCG and porphyry copper-gold deposits.

Drill hole
Information
  • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
    • easting and northing of the drill hole collar
    • elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar
    • dip and azimuth of the hole
    • hole length
  • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.
  • No drillhole data is reported in this release

 

Criteria JORC Code explanationCommentary
Data aggregation methods

  • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.

  • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

  • The assumptions used for any reporting of metal equivalent values should be clearly stated.

  • No data aggregation was used in reported exploration results.
Relationship between mineralisation widths and intercept lengths

  • These relationships are particularly important in the reporting of Exploration Results.

  • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

  • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. 'down hole length, true width not known').

  • No drillhole or intercept data is reported in this announcement
Diagrams
  • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.
  • The Company has included various maps and figures showing the location of sampled outcrop including GPOS coordinates on local projection
Balanced reporting
  • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced avoiding misleading reporting of Exploration Results.
  • No assay results were reported in this announcement
Other substantive exploration data
  • Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
  • The Company is not aware of any other substantive exploration data relevant to its activities.
Further work

  • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).

  • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

  • The Priority for Solis is the EIA and drill permitting which will progress on the Chancho al Palo and Ilo Este assets throughout the year, Solis will commence drill permitting processes at Cinto and advance where possible utilising no invasive techniques on all new applications areas
