Radius Gold options system of gold-silver rich diatreme breccias in

Chihuahua, Mexico

Vancouver, Canada: Radius Gold Inc. (TSX -V: RDU) is pleased to announce that it has signed

a binding agreement with a private Mexican company to option the 473-hectare Tarros Project

which is host to several large gold silver mineralized diatreme breccia bodies. The Tarros Project

is located 50km north of Radius’s new Amalia discovery (see press release 19 September, 2017)

in the Sierra Madre Gold Silver belt in the State of Chihuahua, Mexico.

Tarros Project

The Tarros Project is apparently unexplored, apart from limited historic artisanal-scale mining of

surface outcrops on several of the outcropping bodies. It has been reported that Noranda briefly

held the property in 1992- 1993 but no records of work are known. Epithermal Au -Ag

mineralization has been s ampled by Radius in several explosive hydrothermal or diatreme

breccias bodies within an area roughly 3.5km x 1km. The size of the largest mineralized breccia

bodies observed to date exceeds 250m x 250m.

Radius senior geologists visited the property in June 2017 during a regional prospecting trip and

observed extensive exposures of volcanic hosted, highly altered explosive textured breccia that

were cemented by silica and iron oxides. The breccia bodies were pocketed with pits, tunnels,

shafts, glory holes and open cavities where material had been removed by artisanal miners and

processed for gold. 26 rock chip samples were collected from three separate breccia bodies with

different breccia compositions, of which 24 samples returned significant gold silver values. The

average of all 26 samples assayed 1.42 g/t Au and 66 g/t Ag.

The large size potential combined with the disseminated and distributed nature of the gold- silver

mineralization indicates potential to discover a large bulk tonnage deposit. During the initial

property visit 7 distinct large breccias were observed. Brief descriptions of the main breccia

bodies are set out below.

Rosario Breccia

The Rosario Breccia is the northern most breccia body with an estimated minimum size of 150m

x 60m. It is a large irregularly shaped breccia body, with several pits and tunnels where artisanal

miners produced gold. It is hosted within and comprised of andesite volcanics, with clasts all

highly altered and cemented by clay , silica and iron oxides. A continuous chip sample in an old

pit on the eastern side of the breccia assayed 1 0m at 2.95 g/t Au and 18 g/t Ag (5 samples of

2m). The mineralization is open in all directions. 120m NW of the first channel on the margin

of the breccia, a second continuous chip assayed 3m at 0.88 g/t Au and 139 g/t Ag (3 samples of

1m).

Regalito Breccia

The Regalito Breccia has an irregular oval shape and is estimated at 200m x 150m. The breccia

is hosted within and composed of andesite volcanics. The clasts are all strongly clay altered with

variable sulphides, silica and iron oxides cementing the matrix. The breccia is zoned , with the

western side intensely silicified with some stockwork veining . Radius collected 8 rock chip

samples (2m each) of various breccias in a zone 100 x 20m , with 7 of the samples containing

significant gold and silver mineralization. The average of the 8 samples graded 0.78 g/t Au and

101 g/t Ag.

La Bufa Breccia

La Bufa, on the western side of the Tarros P roject, is elongated NS approximately 300m by 40m

wide. It is the only breccia hosted within granodiorite intrusive. In general, the breccia is

strongly silicified with broken quartz and veining, abundant disseminated pyrite and iron oxides.

There are a few tunnels and small pits, but La Bufa has not been mined as intensely as the other

volcanic hosted breccias . This breccia was not sampled in the first reconnaissance but was

subsequently sampled by Radius and assays are pending.

San Nicolas Breccia

The San Nicolas B reccia forms a low hill and has an irregular shape roughly 250m long and

250m wide, hosted within and composed of andesite volcanics. Strong clay alteration of the

breccia, zones of intense silicification and iron oxide cement are observed similar to the other

breccias where Radius has sampled significant Au and Ag values . Historically the breccia was

mined from several underground tunnels and pits . This breccia was not sampled in the first

reconnaissance but was subsequently sampled by Radius and assays are pending.

San Miguel Breccia

The exposure of San Miguel Breccia is at minimum 200m x 50m elongate roughly NS. The

breccia is full of many tunnels and pits where historic miners removed gold rich pods. Radius

geologists walked the length of the breccia stopping at various interval s to sample the different

breccias types. In total 9 samples were collected over 200m and all samples returned significant

gold silver mineralization, averaging 1.48 g/t Au and 43 g/t Ag.

Discussion

The Tarros system of hydrothermal breccias is a significant discovery and acquisition for Radius

in Mexico. The scale of the breccias mapped to date is large with the 6 known breccias having a

combined size of 14 hectares occurring over 3.5km x 1km , all with historic evidence of

underground mining and surface pits where local miners report recovery of high grade gold and

silver. The results of Radius ’s initial reconnaissance sampling, where 24 out of 26 rock chips

returned significant gold and silver values, indicate the potential to discover a large bulk tonnage

deposit. Radius plans to quickly secure access agreements with the local land owners and

commence detailed grid based and channel sampling to define drill targets.

Maps and photos of the Tarros Project will be available on the Company’s website.
