TUDOR GOLD Step-Out Hole Hits Large, Continuous Gold-Bearing System At Treaty Creek Property (0.981 g/t Gold over 563.8 meters in CB-18-39)
Hole CB-18-39 is one of the three holes reported here that were part of the nine-hole 2018 drill program on the Copper Belle zone of the Company’s Treaty Creek property, in the “Golden Triangle” area of north-western BC (see map below). Results of core sampling have now been received for all of the nine holes completed. The first six holes were reported in the August 24 and October 30 news releases.
Walter Storm, President and CEO, stated: “This very positive intersection in the final hole of the year at Treaty Creek exhibits particularly strong gold values for a porphyry-style deposit. It is certainly the best result to date at Copper Belle – in terms of grade x length – being some 50% longer than the previous longest intersection. We drilled 9 deep holes in 2018, testing a large area with a wide-spaced drill pattern, a program which has expanded the Copper Belle zone to the north and northwest; discovering broad intercepts of gold mineralization adjacent to similar wide intercepts reported in 2017. The target next year will be more drilling north and northeast of Hole CB-18-39, expanding on the significant grade and scale of the gold mineralization encountered.”
Copper Belle significant drill results
CB-18-39 intersected mineralization from a depth of 141.5 m to the end of the hole at 705.3 m, averaging 0.981 g/t Au over 563.8 m. The hole also contained higher grade sections, such as 1.719 g/t Au, with 10.4 g/t Ag, over 55.5 m and, significantly, the hole ended in mineralization, grading 0.673 g/t Au over 38.8 m, indicating potential for continuing mineralization at depth.
CB-18-39 was drilled northwesterly at an angle of -72 degrees. The host volcaniclastic rocks are typically chlorite, sericite and locally potassically altered, however the more strongly mineralized intervals exhibit increased pyrite and stronger silicification than surrounding rocks. This hole also displayed more chalcopyrite than was observed in previous holes. This may indicate that copper grades could be increasing to the north. Silver values were also higher on average in hole CB-18-39, with sections such as 10.4 g/t Ag over 55.5 m from 569.0 m to 624.5 m.
Hole CB-18-39 is the northernmost hole drilled to date and has extended the length of the Copper Belle Zone approximately 90 m northeast from CB-18-37B, to a total known length of 1200 m. Hole CB-18-38; a fill-in hole in the east part of the drill grid, returned wide intercepts of gold mineralization similar to nearby previously drilled holes. Hole CB-18-36 was drilled at the west edge of the drill grid and gold-bearing intervals in this hole indicate that the zone continues at depth in that direction. Gold, silver and copper results for holes CB-18-38 and CB-18-36 are summarized in the table below.
CB-18-38 was a fill-in hole located approximately 60 m and 140 m from the adjacent holes (see map below), providing important information about the width, grade and continuity of the Copper Belle Zone in this area. It was drilled to the northwest at an angle of -72 degrees, parallel to the adjacent holes, and returned three broad intervals of gold mineralization; 0.514 g/t Au over 75.0 m, 0.545 g/t Au over 146.5 m and 0.659 g/t Au over 169.5 m. Additional narrower intervals included 0.561 g/t Au over 19.5 m, as well as 0.540 g/t Au over 12.0 m, which extended to the end of the hole indicating that mineralization probably continues at depth.
The gold mineralized intervals in CB-18-38 are primarily hosted by andesitic tuff and fragmental rocks that are moderately silicified, with chloritic, sericitic and potassic alteration, and are cut by abundant fine pyrite veins and later quartz-carbonate veins. Pyrite content averages about 5%, occurring as fine veins, disseminations and local coarse masses in the host rocks. Gold occurs primarily within the pyritic intervals, as well as within later quartz veins, along with rare chalcopyrite, galena and sphalerite.
CB-18-36 was located at the west edge of the drill grid, and oriented to the northwest at an angle of -72 degrees. It intersected a wide zone of faulting and brecciation that has undergone sericite alteration, with overprinted strong silicification and abundant pyrite. This fault zone, plus underlying brecciated volcanic rocks, is mineralized over a drilled length of more than 140 m, and contains a more strongly mineralized gold zone averaging 0.760 g/t Au over a thickness of 46.5 m. Later quartz-carbonate veins containing pyrite, with lesser galena and sphalerite may also contribute to the gold grades.
The nine holes drilled in 2018 covered an area measuring approximately 370 meters by 250 meters, to depths ranging from 600 to 900 meters.
The most recent drilling has now extended the known length of the porphyry-style mineralized system for over 1200 meters. For locations of the 2018 and other holes in the Copper Belle area please view the map below. The Copper Belle zone has an elongate north-northeast trend, dipping at a relatively flat angle to the northwest. Mineralization appears to be related to an extensive north-northeast trending tectonic zone that may be part of the extensive Sulphurets Thrust Fault structure that also traverses the KSM property to the south.
The objective of the 2018 drill program was to better define the extent of the Copper Belle zone. The results from the 2018 holes have provided additional information about continuity and grade of mineralization that, along with the previous drill results, will be integral for a resource calculation.
Drill core samples were prepared at ALS Global’s (independent) Preparation Laboratory in Terrace, BC and assayed at ALS Global’s (independent) Geochemical Laboratory in North Vancouver, BC. Analytical accuracy and precision are monitored by the submission of blanks, certified standards and duplicate samples inserted at regular intervals into the sample stream by Tudor Gold personnel. ALS Global Laboratories quality system complies with the requirements for the International Standards ISO 17025: 2005.
