Troilus Gold Corp. (TSX: TLG) (OTCQB: CHXMF) is pleased to provide further drilling results from its 100% owned Troilus gold and copper property located Northeast of the Val-d’Or district in Quebec, Canada. A 36,000 metre drill program was designed to confirm and expand existing estimated mineral resources from the past-producing Troilus mine, as well as to explore the down dip and strike extension of known mineralization.
Thirty-three holes, totaling approximately 9,000 metres of drilling were designed to test the down dip continuity and strike extension of mineralization at J4 Zone (Fig 1). The program was also designed to add drill hole information where historic data was limited and/or incomplete. The J4 Zone was the smaller of the two main open pits developed at Troilus during operation. At its deepest, the J4 pit only reached 156 metres in total depth, compared to Z87 which reached a depth of over 350 metres. Drilling from these holes has tested a depth of only 230 metres and has shown sustained strength of mineralization at depth while remaining open down-dip.
The sixteen holes contained in this press release, represent the drilling completed on the Southern half of the J4 Zone open pit target area; located directly South of the J4 Zone Northern half drilling (see Company’s press release dated November 7th, 2018) (Fig 2). All 16 holes intersected gold mineralization and show mineralization continuity at depth, creating growth potential beyond the limits of what was previously estimated (Fig 3). The Southern half of the J4 Zone is showing strong width, similar to that seen in the main zone of Z87. Foliation is creating separate discrete zones of gold-bearing material, that when combined across the targeted geologic unit (foliated diorite), can exceed 40-60 metres of mineralized widths in core (Fig 4).
Drill hole data combined with recent mapping has shown geologic continuity between J4 & J5. Both zones are in fact the same geologically, offset structurally by a pervasive fold regime visible across the entire Troilus property. This new structural thinking suggests J4 and J5 are the same unit often referred to as the “J Zone”.
“We believe the drilling at J4 is a game changer for Troilus and is making the team expand their project vision considerably,” said Justin Reid, CEO of Troilus Gold Corp. “We recognize the value of these near surface results and are eager to apply this new information to the evolving story at Troilus.”
“Our structural approach to exploration has opened up new opportunities across our entire land package,” said Blake Hylands, SVP Exploration at Troilus Gold Corp. “We now better understand the relationship between J4 and J5 and consider them to be one and the same. Recognizing this changes our approach to exploring the region completely.”
The 2018 drilling program has been completed at the Troilus Project. Ninety-one (91) diamond drill holes were completed for a total of over 36,000 metres of drilling and over 26,800 samples. An updated mineral resource estimate is currently underway and is planned to be released before the end of 2018. Regional exploration has now been completed, with samples and mapping expected to form the basis of the 2019 Drill Program, which has been established in conjunction with drilling results and the pending mineral resource estimate update.

36,000 Metre 2018 Drill Program
From 1996 to 2010, Z87 produced the majority of the over 2 million ounces of gold and 70,000 tonnes of copper at the Troilus Project. The Z87 pit was ultimately 350 metres deep and had a strike of approximately 900 metres. The Z87 zone is the focus of the current underground estimated mineral resource, representing over 1.6 million ounces of indicated and 360,000 ounces of inferred material (Figure 5).
Figure 5: Troilus Estimated Underground Resource
Mineralization at the Troilus Project is hosted in breccias and amphibolite grade metamorphic rocks within a much broader, 4.5 kilometre by 400 metre, metamorphosed diorite, known as the Troilus Diorite. Fine-grained disseminated gold accounts for approximately 90% of mineralization at Troilus, primarily as native gold and electrum with grains as large as 20 microns. Chalcopyrite, Pyrite, and Pyrrhotite are broadly disseminated throughout the mineralized body, which are rarely associated with gold (<1-3%). Vein-hosted gold accounts for approximately 10% of mineralization which are responsible for high grade intercepts (>50gpt over 1 m) at Troilus.
The broad geology and style of mineralization at Z87 creates a large deposit area, nearly 1 kilometre along strike and 30-50 metres wide, which remains open both along strike and down dip. The 2018 Drill Program at Z87 was designed to:
2) J Zones (J4 & J5 Zones):
J Zones, two smaller scale historic open pits located 200 metres and 1 kilometres directly Northeast of Z87 are characterized by the same mineralization and geology as Z87; both remaining open at depth and along strike.
Our inherited database suggests the potential for additional near surface mineralization at the J Zones and potentially signifies open pittable resource opportunities. The objective of the 2018 Drill Program, at the J Zones, was to expand the open pit and underground estimated mineral resource below these lesser historic pits, with the intent of recognizing material that could contribute to an early production scenario.
3) Southwest Zone
The Southwest Zone is located along the margin of the Troilus Diorite and surrounding volcanics, 3.5 kilometres Southwest of Z87 (Figure 2). Historically this area exhibited significant mineralization from drilling including intercepts as high as 36m @ 1.23g/t Au, and 18m @ 1.06g/t Au. Historic drilling in this area is limited, leaving the opportunity to explore, and potentially outline new mineralization at surface.
The Southwest Zone exemplifies near term, blue sky opportunity at Troilus, and will be the initial focus of a significant, property wide exploration program. The Troilus Diorite remains underexplored and highly prospective.
During the J4 Zone drill program, one metre assay samples are taken from NQ core and sawed in half. One-half is sent for assaying at ALS Laboratory, a certified commercial laboratory, and the other half is retained for results, cross checks, and future reference. A strict QA/QC program is applied to all samples; which include insertion of one certified mineralized standard and one blank sample in each batch of 25 samples. The gold analyses were by fire-assay on 50 grams of pulp with an atomic absorption finish. Repeats were carried out by fire-assay with a gravimetric finish on each sample containing 3.5 g/t Au or more.
