Callinex Announces Expansion of Rainbow Deposit to Surface and at Depth with Multiple Copper-Gold-Zinc Assays

Rhea-AI Summary

Callinex Mines Inc. (OTCQX: CLLXF) announced positive drilling results from its Rainbow Deposit, located at the Pine Bay Project in Manitoba. Notable highlights include drill hole PBM-158, which intersected 5.0m of 1.56% copper equivalent at a depth of 928m, marking the deepest hole to date. The borehole electromagnetic survey suggests potential for further extensions at depth. Additionally, a newly discovered Red Zone exhibited high-grade copper-gold-zinc assays, with PBM-145 returning 12.0m of 3.43% copper equivalent. The company plans further exploration targeting known deposits and expanding upon previous findings.

Positive

• Drill hole PBM-158 intersected 5.0m of 1.56% copper equivalent at 928m depth, indicating significant mineralization.
• Successful borehole electromagnetic survey suggests further potential for the Rainbow Deposit at depth.
• Discovery of the Red Zone with assays like PBM-145 returning 12.0m of 3.43% copper equivalent, enhancing resource estimates.
• Overall drilling results from 71 holes totaling 39,950m show continuous high-grade copper presence.

Negative

• Assay results from 7,540m of drilling from 17 holes completed in Q4 2021 are still pending, causing uncertainties.
• Limited drilling at the Nash Creek Project revealed no appreciable amounts of silver, diverging from campaign goals.

Highlights:

• Rainbow open at depth with deepest intercept at Rainbow to date, a 225m step-out from previous deepest hole (PBM-111);  
• Subsequent borehole EM survey supports the extension of Rainbow at depth; and
• Multiple near surface copper-gold-zinc assays at the newly discovered Red Zone.

VANCOUVER, BC, Jan. 31, 2022 /PRNewswire/ -  Callinex Mines Inc. (the "Company" or "Callinex") (TSXV: CNX) (OTCQX: CLLXF) is pleased to announce results from an additional 13 drill holes encompassing 5,490m of drilling from the 2021 exploration campaign to expand the high-grade copper, gold, silver and zinc Rainbow Deposit (the "Rainbow"). Assay results from 7,540m of drilling from 17 drill holes completed in Q4 2021 are still pending. The Rainbow is located at the 100% owned Pine Bay Project within a mineral lease, less than 250m from a high-voltage hydroelectric power-line and 550m from a historic shaft with direct road access to processing facilities in Flin Flon, Manitoba  (District Overview Map).

The interpreted strike and plunging direction has been widened and opened up significantly at depth with the intersections of the Yellow Zone in drill holes PBM-146a, PBM-146-W and PBM-158. Drill hole PBM-158, the deepest and most northern hole intersected to date at Rainbow, 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")). PBM-158 is located 225m along strike to the North of discovery hole PBM-111, the most southerly hole to intersect the Rainbow at depth (Rainbow Deposit Long Section). 

Jim Pickell, member of Callinex's technical team, stated, "Given the intense geochemical alteration patterns and favourable geology at the deepest explored levels of the Rainbow VMS deposit, it is exciting that a newly defined strong borehole (PBM-158) geophysical anomaly is located immediately below those high-grade massive sulphides."

A subsequent borehole electromagnetic ("BPEM") survey completed and modeled from PBM-158 indicates significant potential for Rainbow to continue at depth. This is also supported by intense sericite and chlorite alteration that is strongest in the deepest holes drilled into the deposit (Rainbow Alteration Cross Section). The Yellow Zone starts up at 600m below surface and has a strike of 225m based on this most recent intersection. Typically Volcanogenic Massive Sulphide ("VMS") lenses discovered in the Flin Flon Greenstone belt have a depth extent that's 5-8 times the strike.

Alan Vowles, member of Callinex's technical team, added, "I am quite encouraged by the off-hole anomaly in PBM-158 because the Tau indicates it is even a little more conductive than the original off-hole target in PBM-033 that we drilled and discovered the Rainbow. Additionally, because the off-hole target in PBM-158 is below the hole it indicates strong potential that Rainbow continues at depth".

The BPEM anomaly modeled from PBM-158 measures 190m by 400m. The Time Constant or Tau, a measure of conductance, of the off-hole anomaly in PBM-158 is 27.07 milliseconds (ms).  By comparison, the Tau of the anomaly in PBM-033, which vectored to the discovery of Rainbow, was 22.87 ms.

Six drill holes announced have intersected a newly discovered copper-gold-zinc rich Red Zone that remains open towards surface and has been intersected to a depth of 375m below surface.  The Red Zone is highlighted by drill hole PBM-145 which returned 12.0m of 3.43% CuEq (consisting of 0.57% Cu, 0.90 g/t Au, 20.27 g/t Ag and 5.25% Zn). There are still four drill holes that are pending from the assay laboratory above the 200m level.

JJ O'Donnell, Callinex Exploration Manager, stated, "We are pleased to have delineated a new zone as we continue to test the Rainbow horizon to surface. The recent drilling in the Red Zone has produced the highest returned assays for gold and zinc (PBM-145 266m-267m @ 4.29 g/t Au, PBM-145 235m-236m @ 16.8% Zn) to date at the Rainbow Deposit. The new Red Zone illustrates the Rainbow Deposit is a typical VMS displaying stacking of lenses, and metal zonation from copper rich lenses to more zinc rich portions."

Delineation drilling of Rainbow continues to return high-grade copper. PBM-138-W1 intersected the Orange Zone and returned 31.0m of 3.53% CuEq comprising 3.04% Cu, 0.26 g/t Au, 3.55 g/t Ag and 0.74% Zn. PBM-138-W1 is located 15m above PBM-138 which intersected 37m of 6% copper, 0.35 g/t gold, 6.13 g/t silver, 0.09% zinc or 6.33% CuEq and 50m below PBM-118 which returned 5.55m of 7.77% CuEq (See News Release Dated September 7, 2021 and News Release Dated April 26, 2021)

The Company plans to delineate Rainbow within the first 1km of surface and test Rainbow at depth. In anticipation of publishing a maiden resource estimate for the deposits at the Pine Bay Project, drilling will also be completed on the historic Pine Bay Deposit located 650m away. Since the Company discovered the Rainbow Deposit in August 2020, the Company has drilled 71 holes (including 15 wedges) for a total of 39,950m into the deposit area. 

Callinex will soon outline high-priority targets located within the interpreted growth fault corridor which hosts Rainbow and five other deposits, three of which have seen some level of historic production. Additionally the Company will outline targets from the regional Induced Polarization survey that covers 5.5 km of the trend that hosts the Rainbow and Sourdough deposit to the south.

The Company has also received a majority of the assays from the limited drilling to follow-up on silver discovered near surface at the Nash Creek Project located in the Bathurst Mining District, NB during the 2019/2020 exploration campaign. None of the assay results received contain appreciable amounts of silver, a focus of the campaign.  A 2018 PEA on the Company's zinc rich Bathurst projects outlined a mine plan that generates a strong economic return with a post-tax IRR of 36.6% and NPV8% of $239 million post-tax at current zinc/lead prices.

QA / QC Protocols
Individual samples were labeled, placed in plastic sample bags, and sealed. Groups of samples were then placed in security sealed bags and shipped directly to SGS lab in Vancouver, BC for analysis. Samples were weighed then crushed to 75% passing 2mm and pulverized to 85% passing 75 microns in order to produce a 250g pulverized split. 35 elements including copper, zinc, lead and silver assays were determined by Aqua Regia digestion with a combination of ICP-MS and ICP-AES finish, with over limits rerun using an ore grade analysis (two acid digest ICP-AES).  Gold was analyzed by fire assay. Specific gravity (sg) measured for each sample using the pycnometer and water and air method. QA/QC included the insertion and continual monitoring of numerous standards, blanks, and duplicates
