VANCOUVER, BC, July 10, 2023 /PRNewswire/ - Callinex Mines Inc. (the "Company" or "Callinex") (TSXV: CNX) (OTC: CLLXF) is pleased to announce a high-grade copper maiden mineral resource estimate for its 100% owned Pine Bay Project (the "Project") in Manitoba. The Project hosts the high grade copper, zinc, gold and silver Rainbow deposit which is open for expansion in addition to the Pine Bay deposit that sits in close proximity.  The deposits at the Pine Bay Project are Volcanogenic Massive Sulphide ("VMS") which contain significant copper, zinc, gold and silver that the Flin Flon Mining District is well known for.  The resource estimate was prepared by Kirkham Geosystems Ltd. ("Kirkham") for the Company.

The mineral resource estimate, contained within the mineral lease, consists of the Rainbow deposit with an Indicated Mineral Resource of 3.44 Mt at 3.59% copper equivalent ("CuEq") containing 272.4 Mlb CuEq (comprised of 238.3 Mlb Cu, 56.9 Mlb Zn, 37.6 koz Au, 692.8 koz Ag, 2.3 Mlb Pb), an Inferred Mineral Resource of 1.28 Mt at 2.95% CuEq containing 83.4 Mlb CuEq (comprised of 72.1 Mlb Cu, 19.5 Mlb Zn, 11.1 koz Au, 222.2 koz Ag, 0.8 Mlb Pb) and the Pine Bay deposit with an Inferred Mineral Resource of 1.0 Mt at 2.62% Cu containing 58.1 Mlb Cu (Pine Bay Project Block Models Projected to Surface)

Notes:


(1)

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.

(2)

The estimate of Mineral Resources may be materially affected by environmental permitting, legal title, taxation, socio-political, marketing or other relevant issues.

(3)

The Mineral Resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council. It cannot be assumed that all or any of the inferred mineral resources will be upgraded to indicated measured resources as a result of continued exploration.

(4)

The inferred mineral resource in this resource estimate has a lower level of confidence than that applied to an indicated mineral resource and must not be converted to a mineral reserve.  It is reasonably expected that a majority of the inferred mineral resource could be upgraded to an indicated mineral resource with continued exploration.

(5)

The indicated and inferred resource estimate uses a copper equivalent cut-off grade of 1.3% CuEq.

(6)

Copper equivalent resources for the Pine Bay Project were calculated using the following metal prices: Cu at US$3.25/lb, Zn US$1.20/lb, Au at US$1,850/oz, Ag at US$22.50/oz.  Foreign exchange rate of CDN$1.00 = US$0.75.

(7)

Metallurgical recoveries have been assumed to be 80% Cu, 80% Zn, 40% Au and 40% Ag.

(8)

Mineral resources are not mineral reserves until they have demonstrated economic viability. Mineral resource estimates do not account for a resource's mineability, selectivity, mining loss, or dilution.

(9)

All figures are rounded to reflect the relative accuracy of the estimate and therefore numbers may not appear to add precisely.

The Company will file a National Instrument 43-101 Technical Report that supports the disclosure of the Mineral Resource Estimate within 45 days of this news release.

Pine Bay Project Access and Geology

JJ O'Donell, Callinex's Exploration Manager said, "The maiden resource estimate covers a small footprint on our extensive exploration land package in Manitoba.  As part of our ongoing drilling campaign we will test high-priority targets at Rainbow, Alchemist, Odin and Cabin with the objective of adding further resources."

The Pine Bay Project, consists of a group of 77 contiguous mineral claims (dispositions) and one Mineral Lease totaling 6,795 hectares. Both the Rainbow and Pine Bay Mineral Resources are located on the Mineral Lease 59 which totals 782 hectares. The Project is located 14 km east of the city of Flin Flon Manitoba, and access is gained via driving southeast 15 kms along provincial highway #10, heading north for an additional 10 kms along old provincial Highway #10 (~5 kms) and the fully serviced Northstar Road. 

The Rainbow and Pine Bay deposits are a felsic-hosted VMS deposits that dips 78 and 82 degrees (respectively) to the east, with the Rainbow deposit having a strike length of 310m and a maximum horizontal thickness of 32.0m. The Pine Bay deposit has a strike length of 190 m and a maximum horizontal thickness of 42.0m. Massive sulphides have been intersected on the Rainbow deposit from 100m below surface to a depth of 897m from a total of 66 drill holes totaling 38,249m. Massive sulphides have been intersected on the Pine Bay deposit from 10m below surface to a depth of 375m from a total of 76 drill holes totaling 10,123m.

Callinex's Pine Bay Project encompasses the majority of the Baker Patton Complex (BPC), the largest exposed felsic (rhyolitic) volcanic accumulation in the Flin Flon portion of the Flin Flon-Snow Lake Greenstone Belt (Flin Flon Greenstone Belt Regional Geology). This is especially important since the majority of the VMS deposits occurring within the Flin Flon Belt of Saskatchewan and Manitoba are almost always hosted by rhyolitic flows and volcaniclastic rocks within predominantly mafic terranes. Of additional importance is that these felsic (rhyolitic) rocks only account for a small portion of the total volcanic pile (5-10%). Of particular exploration interest to Callinex's Pine Bay Project, is the very large exposure of intensely altered (chloritic, sericitic and silicic alteration) felsic rocks that have collectively been called the Baker Patton Alteration Zone, encompassing an area with a minimum footprint of 700m by 1000m. A very large footwall alteration system such as this would normally be expected to be accompanied by a large VMS system and has consequently been the target of many exploration companies preceding Callinex.

Pine Bay Project Exploration

Jim Pickell, a member of Callinex's technical team, commented, "After working and contributing to the discovery of several significant deposits in the Flin Flon area, I've always been intrigued by the special geological setting in the Pine Bay area and its continued proven propensity to host prolific VMS systems. Nothing that I've seen in our current round of exploration reduces that initial level of optimism for the property."

The Rainbow deposit was initially discovered with a discovery hole in 2020.  In a relatively short time frame, the Company has carried out a number of extensive drill programs to define a high-grade copper maiden mineral resource at the Rainbow deposit.  Additional drilling has targeted a number of high-priority targets resulting in the discovery of the nearby Alchemist and Odin prospects, which are not part of this maiden resource estimate.

The focus of the Company is to further expand the size of the high-grade Rainbow deposit both laterally and at depth.  The last deep hole at the Rainbow deposit, drill hole PBM-158, was the deepest and most northern hole, which intersected the Yellow zone and returned 5.0m of 1.56% copper equivalent ("CuEq") (consisting of 1.45% copper ("Cu"), 0.07 g/t gold ("Au"), 1.86 g/t silver ("Ag") and 0.11% zinc ("Zn")).  

Follow up drilling is also planned to step out vertically above and below Alchemist.  The last reported drill hole of Alchemist, ALC-114, intersected 4.40m of 4.02% CuEq including 1.60% copper ("Cu"), 5.14% zinc ("Zn"), 0.40 g/t gold ("Au") and 21.78 g/t silver ("Ag")

The fully funded drill campaign is also targeting Odin, which is directly in between the Alchemist and Rainbow deposits. Drill hole PBM-191 intersected one of the highest precious metals intervals to date at Odin with 0.52m of 5.32g/t Au, 56.67g/t Ag with trace copper and zinc and interpreted to be on the Odin horizon.

The Company is further exploring the high-grade historic Cabin deposit.  In late 2016, the Company intersected 10.3m grading 6.0% Zn, 1.8 g/t Au, 60.4 g/t Ag, 0.7% Cu and 0.4% Pb in drill hole 284-3-93-DPN (see news release dated October 18, 2016).  Since the discovery of Rainbow and now Alchemist, the Company has a deeper understanding of how VMS deposits sit along the stacked horizons located within the main controlling growth fault corridor at the Project.  The Company has now refined exploration target areas and is currently drill testing these targets to follow up on previous high-grade intersections.

Model Parameters and Methods for the Rainbow Depoist and Pine Bay Deposit Resource Estimates

The database for the mineral resource estimate for Rainbow Deposit consisted of 104 drill holes (including 14 wedges) totalling 60930m, of which a total of 66 drill holes totaling 38,249m intersected the mineralization wireframes used for the mineral resource estimate.  The drill hole database contained assays for copper, zinc, gold, silver and lead as well as other metals of no economic importance. 

The database for the mineral resource estimate for Pine Bay Deposit consisted of 131 drill holes totalling 25,672m, of which a total of 76 drill holes totaling 10,123m intersected the mineralization wireframes used for the mineral resource estimate.  The drill hole database contained assays for copper only.  In October 2022, Kirkham carried out data verification on the historical data and check sampling to validate the use of the database for estimation of the inferred resource at Pine Bay. The methodology employed for the resource estimation at Rainbow and Pine Bay is a follow:

  • The estimate was carried out using separate block models constrained by 3D wireframes of the individual mineralized zones. The block model is comprised of an array of blocks measuring 10m x 2m x 10m which employ partial percentages for volumetric accuracy, with grades for Cu, Zn, Pb, Ag and Au interpolated using Ordinary Kriging within the Rainbow deposit and Inverse Distance to the Second Power (ID2) weighting for the Pine Bay deposit for copper grades. Copper equivalent values were subsequently calculated from the interpolated block grades.
  • The interpolation for Rainbow was carried out in two passes with the first pass using search radii of along strike and down dip of 150m x 150m and 30m perpendicular to dip. Composites were restricted to a minimum of 1 and a maximum of 12 composites, with a maximum of 3 composites from any one drill hole. The second pass used a restricted search radii along strike and down dip of 60m x 60m and 30m perpendicular to dip. Composites were restricted to a minimum of 6 and a maximum of 18 composites, with a maximum of 4 composites from any one drill hole.
  • The interpolation for the Pine Bay deposit was carried out in two passes with the first pass using search radii of along strike and down dip of 150m x 150m and 60m perpendicular to dip. Composites were restricted to a minimum of 1 and a maximum of 12 composites, with a maximum of 3 composites from any one drill hole. The second pass used a restricted search radii along strike and down dip of 60m x 60m and 30m perpendicular to dip. Composites were restricted to a minimum of 5 and a maximum of 16 composites, with a maximum of 4 composites from any one drill hole.
  • Bulk density was determined on each sample submitted to SGS laboratories in Burnaby, BC  measured by the gas pycnometer method on pulp samples. For each sample interval, sub-samples were taken from each individual length of core and the weighted average for the sample used. Density values were interpolated on a block-by-block basis using an inverse distance to the second power for the Rainbow deposit. An average value of 2.90 t/m3 was assigned to the Pine Bay Deposit.
  • Composite values have been capped in order to remove the effects of potential overestimation due to statistical outliers. Therefore, outlier values for each of the metals estimated within the Rainbow deposit were capped at the threshold levels of 7.5%-15% copper, 6% zinc, 20-30 gpt silver and 1.5 gpt gold. For Pine Bay deposit the threshold chosen for capping was 4%-4.5% copper.
  • The mineralized domain solids were defined using a combination of geological constraints and grade boundaries in addition to consideration of potential reasonable mining thickness. Intervals that were not sampled were assigned a zero grade.
  • For all zones, blocks are classified as Inferred if they are included within 150m of at least two drill hole intercept. Blocks within 40m of the nearest intercept and 40m average for all composites, estimated by at least four drill holes and at least 12 composites were classified as Indicated. However, an interpreted boundary is the final determination of indicated and inferred resources in order to remove outlier blocks and the "spotted dog" effect. In addition, continuous potentially underground mining shapes were created to demonstrate "reasonable prospect of eventual economic extraction".
