VANCOUVER, British Columbia, Nov. 09, 2022 (GLOBE NEWSWIRE) -- Trillium Gold Mines Inc. (TSXV:TGM, OTCQX:TGLDF, FRA:0702) (“Trillium Gold” or the “Company”) is pleased to report on the results of the 2022 summer exploration and drilling activities at its Newman Todd Complex (NT Complex) in Red Lake, Ontario. The Complex comprising the Newman Todd and adjoining Rivard property located some 26 km from Evolution Mining’s Red Lake Operations, offers significant exposure to gold mineralization in a world-class mining jurisdiction.
A total of 7,665 metres in 17 holes were drilled at the NT Complex in the first half of 2022 and remaining assay results have now been received. The Company ceased drilling at the end of June to allow for all pending results to be received and compiled.
Newman Todd Complex Today – Breaking the structural barrier
With prior exploration at the NT Complex having almost exclusively focused on the NT Zone itself, new structural and lithological interpretation by Trillium’s geological team of Red Lake experts redirected drilling to areas outside of the NT Zone, particularly below 400 metres from surface where previous drilling was virtually non-existent. Trillium’s initial step-out holes along the east-west extensions of the Main Zone Fault all successfully encountered significant gold intersections that further follow-up will test the potential for gold mineralization at other targets on the greater Newman Todd property.
Drilling to date has confirmed the geological team’s premise that additional high-grade zones can be found to the southeast and are still controlled by the east-west structural corridors. This interpretation is no more apparent than in the two most recent holes (NT22-211 and -212) drilled into the hanging wall rock sequence about 100 to 250 metres below all previous drill holes (see NR dated September 26, 2022). The hanging wall gold occurrence, within the broader significant interval of 8.75 g/t Au over 20.4 metres (including 549.0 g/t Au over 0.3 metres), and 40.56 g/t Au over 4.18 metres (including 136.0 g/t Au over 1.08 metres), indicates that gold mineralization associated with the NT Zone and east-west shears (eg. Main Zone Fault), continues southeast of the NT zone, thus expanding the possible drill target areas and potential mining pit shell within the project area.
The more meaningful high-grade intersections have all occurred at these cross-cutting occurrences; previously reported holes: NT20-169 [7.05m at 15.41 g/t Au including 4.3m at 23.88 g/t Au and 1.12m at 69.85 g/t Au], and NT21-194 [9m at 19.73g/t Au including 1.55m at 102.16 g/t Au] on the Camp Fault].
Historically, drilling in this region was generally discontinued prior to intersecting this hanging wall mineralization when drilled from the foot wall. Very little drilling in the opposite direction was carried out overall, leaving the potential of this mineralization unrecognized until now. Several other structures displaying significant widths of mineralization are being identified by stepping out to the north and south of the Main Zone Fault.
After several months, our team is more confident than ever that they will be able to apply this established theory successfully at depth and on strike, both of which remain completely open.
Advancing the Open-Pit Scenario
Drill holes NT21-204, NT22-205, NT22-208/A and NT22-210 (see Figure 1 below) successfully targeted observed and interpreted east-west fault trends associated with previous high-grade intersections. These holes were intended to expand the higher-grade zones downwards and into the sparsely drilled foot wall portion of the NT Zone at depth. Holes NT21-204 and -205 were successful in intersecting mineralized NT Zone material and an east-west breccia fault. Significant assays included 3.36 g/t Au over 10.94 metres from 187.36 metres and 1.59 g/t Au over 17.92 metres from 399.13 metres in NT21-204.

Drill holes NT22-208/A and NT22-210, again targeted the NT Zone foot wall margin as well as the hanging wall mineralization seen in previous drilling. NT22-210 was drilled to also intersect the hanging wall side of the projected high-grade trend. The results from these holes of 1.76 g/t Au over 5.95 metres from 291.05 metres in NT22-208A and 1.94 g/t Au over 23.8 metres from 52 metres in NT22-210 and a number of lower grade but wide zones show that other significant east-west structures are present in this area for future follow-up.
Hole NT22-209 was located to test the NT hanging wall mineralized chert-magnetite zone, and then push westward into the foot wall to follow-up previous results from Rivard drilling, in the sparsely drilled southwest NT Zone. Only narrow low-grade results were obtained.
Drill holes NT22-206 and NT22-207 were drilled in the north-east area of the NT property, targeting the east extension of the Main Zone Fault in the area where it is interpreted to intersect the eastern ultramafic unit mapped on the property. This area was identified as having a similar geological and structural setting as mineralization occurrences in the east area of the Red Lake greenstone belt, for example at the Red Lake Mine. The area is also where a number of elevated assay results were received from earlier drilling, grouped within the hanging wall zone of gold resources previously outlined. Significant assays from these holes include 1.71 g/t Au over 3.46 metres from 124.7 metres in NT22-206 and 4.12 g/t Au over 3.85 metres from 51.85 metres in NT22-207, as well as a number of lower grade but wide intervals in both holes. The Main Zone Fault was identified in core and the presence of up to 2% sphalerite (Zn); and very fine visible gold (VG) shows the potential of this area for follow-up work.
Drilling on the Rivard property during 2022 began with holes RV22-37 to RV22-39 targeting below previous high-grade results, both in drilling and channel sampling, in the south-central area of the property. A number of lesser, but still significant, gold assay results were obtained with eight VG occurrences identified as they expanded both the strike and depth limits of the mineralized vein trends.
Holes RV22-40 to RV22-42 were drilled in the northeast area of the Rivard property and tested the west extension of the Main Zone Fault feature and in an area of previous high-grade gold assay results from surface at the collar location and along strike from historical drill holes. RV22-40 obtained a good result from near the collar of 2.79 g/t Au over 7.95 metres from 32.85 metres downhole. Holes RV22-41 and RV22-42 both intersected the Main Zone Fault and obtained low level intersections near the fault.
RV22-43 was drilled to test surface sampling gold results and the southeast extension of interpreted mineralized vein trends in the sparsely drilled east-central portion of the Rivard property. Only low-level gold results were obtained but VG was noted immediately below the collar.

During June 2022, the Company continued with the surface channel sampling program over the high-grade quartz veins on the Rivard portion of the property, which began in 2021. This work was undertaken to better define the 3D geology of the Rivard portion of the property and obtain a better understanding of the gold mineralization controls from detailed examination of the high-grade veins seen on surface. Early results of this work showed a strong correlation between the high grades and a subtle change in the vein orientations, in locations where an east-west structural corridor was observed and would likely create plunging high-grade “pipes” related to these structural intersections.

Three more areas were channel sampled in 2022: on the Main Zone Fault west extension, the north-central portion of the property outside the limits of the historically trenched areas (North Contact), and extensions of the VG1 and VG2 area. In this program, all samples were cut at regular intervals both along and across the observed veins. Listed below are the weighted average grades for the samples along the length of the gold veins. A full listing of all results and location maps can be found at www.trilliumgold.com.

Alteration and widespread gold mineralization occurs extensively within structurally and chemically favourable rocks on the property. Historically, the Rivard Property is known to contain both visible gold in narrow high-grade veins, as well as in broader zones of lower grade gold mineralization ranging from <1 g/t Au to over 560 g/t Au (see NR dated June 29, 2021 – New Discovery Hole at Rivard Confirms High-Grade visible gold with 129.79 g/t over 1.30 metres).
Previous channel sampling results have shown that the significant gold values are not confined to small areas within the veins but occur over significant strike lengths, and at considerable grades, along the veins following structural plunges.
Understanding the controls and geometry of the high-grade mineralization seen on surface and intersected in drilling on Rivard is important to the expansion of the overall system. Trillium’s geological team has shown that this vein system is influenced by the east-west structures evident in the NT Zone which will increase the success in delineating high-grade shoots that can favourably impact Newman Todd’s economic prospects.
For the 2021 channel sampling results, see the news release dated March 22, 2022.
All Newman Todd Complex drilling was supervised by Paul Barc, PGeo. The drilling was conducted by Rodren Drilling Ltd. of West St. Paul, Manitoba. Drill core was logged and sampled in a secure core facility.
Core samples from these programs were cut in half, using a diamond cutting saw, and half cores were sent for analysis to Activation Laboratories Ltd. in Dryden, ON, an accredited mineral analysis laboratory. All samples were analyzed for gold using standard Fire Assay-AA techniques. Samples returning over 10.0 g/t gold were analyzed utilizing standard Fire Assay-Gravimetric methods. Any samples with results greater than one ounce per ton gold were also analyzed with a standard 1 kg metallic screen fire assay. Certified gold reference standards, blanks and duplicates are routinely inserted into the sample stream, as part of Trillium Gold’s quality control/quality assurance program (QAQC) to monitor accuracy and precision. No QAQC issues were noted with the results reported herein.
References to visible gold (VG) are factual observations and should not be construed as quantifiable grade. All drill interval lengths and widths referenced herein are measured downhole.
