Tower Resources Identifies High Grade Till Samples at Nechako
Tower Resources Identifies High Grade Till Samples at Nechako
Vancouver, B.C. – May 15, 2018 - Tower Resources Ltd. (“Tower” or the “Company”) is
pleased to provide an update at the Company’s Nechako gold project in British Columbia.
In 2017 Tower contracted Overburden Drilling Management (“ ODM”) to complete an
investigation of the overlying tills at Nechako using their wel l established reverse
circulation (“RC”) drilling and indicator mineral analyses. This program has su ccessfully
identified an area of highly concentrated sulphide grains in th e tills, including pyrite,
chalcopyrite and sphalerite that carry highly elevated grades o f gold, silver, copper, lead
and zinc.
“Historical exploration at Nechako by Placer Dome and Rio Tinto focused exclusively on
porphyry Cu deposits. Tower’s 2017 RC program has demonstrated the potential for Au
and Ag in an untested area of the property and has considerably narrowed the search for
a new deposit. This represents an exciting new opportunity in the exploration of Nechako,
one that we will follow up on with diamond drilling in 2018. Similar methodology has been
successfully employed to discover a number of Canadian gold dep osits including
Blackwater (30 km southwest of Nechako), the Rainy River mine a nd the Casa Berardi
mine in Quebec” added Garett Macdonald, President & CEO.
Results of 2017 reverse circulation program
A total of 38 RC holes were completed at Nechako with overburde n depths varying from
5 to 50 metres. Till samples weighing approximately 10 kg were collected from top to
bottom in the till section in each hole, typically over 1.5 m i ntervals. A heavy mineral
concentrate (“HMC”) was prepared from each sample to extract any available gold and
sulphide mineral grains that had been dispersed in the till dur ing glaciation. All HMCs
were then analyzed geochemically for Au and other elements of interest. A large sulphide
mineral dispersial train was identified in the till glacially d own-ice from the Kluskus Road
Porphyry (Fig. 1) and directly below a gold grain dispersal train identified in Tower’s earlier
(October 2016) surface till sampling program.
At Nechako the Cu content of the sulphide-bearing HMCs mirrors the known low 0.05-
0.1% Cu grade of this porphyry but the Au and Ag contents of the HMCs are much higher
(typically 1-5 g/t, ranging up to 10 g/t) than anything known in or near this porphyry (Table
1). As at the Rainy River project, the till in the Au dispersal train is so enriched in sulphides
that the HMCs are much larger than normal, significantly diluting the Au analyses. In order
to compare the relative Au anomaly strength between sulphide-ri ch and sulphide-poor
samples, all Au values over 500 ppb (0.5 g/t) were normalized t o a standard 25 g HMC
weight. To compare the anomaly strength between drill holes, a further adjustment was
made for the number of anomalous samples per hole, similar to t he grade x thickness
calculation used in diamond drilling. Even without normalizing , however, the Au content
of the till HMCs is two to three times higher than that of HMCs from an RC hole drilled on
the Blackwater dispersal train 600 m down-ice from the centre o f the deposit. During the
RC program a large, new porphyry stock called the Blue Road Por phyry on the eastern
part of the property was also discovered (Fig. 1). This porphyry has undergone pervasive
argillic alteration (sericite + pyrite) and appears to be related to the smaller Kluskus Road
Porphyry to the west.
