Fifth high grade antimony prospective trend within 4 kilometre radius of Bald Hill Deposit in New Brunswick, Canada

Tri-Star (AIM: TSTR), the integrated antimony development company, is pleased to provide an update of the ongoing exploration programs on the Bald Hill antimony property. Reconnaissance exploration programs have highlighted two new prospective antimony trends in the Bald Hill area which have returned prospecting assays of 4.61% Sb and 21.7% Sb, respectively. These new areas together with the existing 3 trend areas are within a 4 km radius of the original Bald Hill deposit. Results from new and existing areas and occurrences are set out below:

New prospective trend areas:

· The "28 East" trend is located 2.8 km east of the original Bald Hill Deposit ("Bald Hill Deposit"). Recent reconnaissance prospecting has returned assay results of 21.7% Sb from angular boulders. (Figure 1 and Table 1).

· The"Carpenter Brook" trend is located 3km south west of the Bald Hill Deposit. Recent reconnaissance prospecting has returned assay results of 4.61% Sb from boulders collected by Tri-Star in the Carpenter Brook area corresponding to the location of historical work undertaken by Maritime Resource Research Limited ("MRR") (Table 1). Compilation of previous exploration work in the Carpenter Brook area indicates a Sb soil anomaly ranging to 1,300 ppm Sb, 970 metres in length and up to 360m wide, orientated in a NNW - SSE trend which remains open to the north and south. (Figure 1, Table 1 and Table 2).

Existing prospective trend areas:

· The Bald Hill Deposit where drilling over a 700 metre length returned intersections ranging as high as 11.70% Sb and 6.74 % Sb over core-intervals of 4.51metres and 3.30 metres, respectively. The extent of mineralization remains open.

· The Bald Hill South Discovery ("South Discovery"): Exploration surveys indicate that the overall northwest - southeast trending Bald Hill Deposit - South Discovery trend is at least 2.2kms long. The May-June 2014 trenching program in the South Discovery outlined a new area of antimony mineralization grading 9.04% Sb over 2.60 metres including 12.32% over 1.7 metres from channel sampling (see announcement dated July 16, 2014). 

· Bond Road: Located approximately 4km east of the Bald Hill Deposit, soil assay results outline a well-defined, 600m long Sb anomaly trending northwest, similar to the orientation of the fault-fill type mineralization at Bald Hill. Prospecting by Rockport on the Bond Road grid area discovered numerous boulders that assayed greater than 15% Sb (see RNS announcement dated July 16, 2014).

The Bald Hill Deposit, South Discovery and Bond Road trend areas are further described in the Bald Hill NI 43-101 Technical Report dated 28 October 2014 available on the Company's website further to the announcement dated 31 October 2014.

Ken Hight, CEO of Tri-Star Antimony Canada Inc., stated: "We are excited by the indication of multiple northeast-southwest antimony trends developing in the Bald Hill area and the obvious upside potential this implies. Our 100% owned land package in the Bald Hill area consists of 891 claim units totalling 200 km2 and 35 kilometers in length. We have explored only a small portion of this large property and numerous historic indications of antimony have been found throughout the land package. Results demonstrate the emerging potential of the Bald Hill antimony project."

Roger Dahn, Vice President - Exploration of Tri-Star, recently presented an update titled "The Bald Hill Antimony Deposit- An Exploration Update" at the 2014 EMP Conference in Fredericton, New Brunswick on November 3, 2014. The presentation will be available on the Company's website at www.tri-starresources.com shortly.

Table 1: 28 East and Carpenter Brook - October - November 2014 Prospecting Results

Compilation of previous gold oriented exploration work completed by MRR in 1986 and 1987 (New Brunswick Assessment # 473379) indicates a large Sb soil anomaly ranging to 1300 ppm Sb, 970 metres in length and up to 360m wide in the Carpenter Brook area. The anomaly extends to the limits of the 1986-1987 soil geochemical survey and remains open to the north and south. The soil anomaly is orientated in a NNW - SSE trend which is similar in orientation to the Bald Hill Deposit and the South Discovery. Recent prospecting by Tri-Star in November 2014 located a mineralized angular boulder assaying 4.61% Sb (Sample 9576 - Table 1) located approximately 120 metres east of the 1300 ppm Sb soil site identified by MRR. This occurrence enhances the indicated economic potential of this new Sb trend. Detailed exploration programs are planned during 2015 to evaluate the Carpenter Brook target area.

MRR collected a total of 274 B-horizon soil samples which were analyzed for 28 elements including Sb. The soils assays were performed in May 1987 by Neutron Activation Services Limited of Hamilton, Ontario using INAA methods. Basic statistics of the soil geochemical results are presented in Table 2.

Assays of the Company's prospecting samples were performed by Activation Laboratories Ltd, Ontario, using Code 8 Sb assay by Sodium Peroxide Fusion followed by ICP analysis. Activation Labs runs internal blank and standard samples as part of their quality control.
