MAMMOTH INTERSECTS 45.4 METRES GRADING 0.63

GRAMS PER TONNE GOLD EQUIVALENT IN DIAMOND

DRILLING AT ITS TENORIBA PRECIOUS METAL

PROPERTY, MEXICO

Toronto, Canada (April 12, 2018) - Mammoth Resource s Corp. (TSX-V: MTH), (the “Company”) is

pleased to announce results from two additional dia mond drill holes on its Tenoriba precious metal

property in the Sierra Madre region of southwestern Chihuahua State, Mexico. The results are for the

third hole in the Masuparia area of the property; TEN 17-04, and the first hole ever to be drilled at the

Los Carneritos area of the property; TEN 17-07, located 800 metres nor theast of hole TEN-04. The

intersection at Los Carneritos extends the strike length of gold mineralization on the property a

total of almost four kilometres within a High Sulphidation system with mineralization open at least

one kilometre both to the east and west of the four kilometre trend where gold has been sampled

on surface.

Results are shown in the table below. Drill hole surface locations and drill cross sections illustrating the

location and depth of the mineralized intervals rel ative to geophysical and topographic features are

available on the Company's website under the 'Projects' section; 'Maps, Images and Photographs'.

Thomas Atkins, President and CEO of Mammoth comment ed on the drill results stating : “We're

very pleased with these two holes to have intersect ed gold mineralization in the Los Carneritos area

almost one kilometer to the east of any prior drilling on the property and to have extended mineralization

by at least 100 metres to the west of prior drilling in the Masuparia area.

"Drill hole TEN 17-04 is a step-out hole more than 100 m west of hole TEN 17-05 in the Masuparia area

of the property where among other intersections ann ounced on March 1st from hole TEN 17-05 there

occurred 0.63 grams per tonne gold equivalent over 27 metres and 1.32 grams per tonne gold

equivalent over 23.5 metres. Drill hole TEN 17-05 is a 50 metre step out to the northwest of hole TDH-

07 which was drilled in 2008 and which assayed 2.35 grams per tonne gold equivalent over 47 metres,

including 5.33 grams per tonne gold over 4 metres. The structure intersected in these holes can be

followed on surface for a strike length of 800 metres to the north and may also intersect an approximate

500 metre east-west geophysical feature in this area.

"To intersect 39 metres of a grade that is almost twice the cut-off grade for economically producing heap

leach gold mines in Mexico in the first drill hole ever drilled into the Los Carneritos area in hole TEN 17-

07 is a terrific success. Los Carneritos is located almost four kilometers to the east of the furthest

western drill hole from this program at El Moreno. What's particularly encouraging about this hole was

the abundance of vuggy silica in the core, vuggy si lica being a strong indicator of the elevation for gold

mineralization within High Sulphidation systems.

"Gold mineralization remains open to the east and w est for at least another kilometer in from the Los

Carnertitos and El Moreno areas, respectively. Mamm oth expects to drill another two to three holes

within the large one by one and a half kilometre area of Los Carneritos to test other targets as part of the

current drill program."

TEN-17-04

Drill hole TEN 17-04 is a 50 m step out to the nort hwest of hole TDH-07 drilled in 2008 which assayed

2.35 g/t over 47 m, including 5.33 g/t gold over 4 m. It is believed the structure(s) intersected in h oles

TDH-07, TEN 17-04 and TEN 17-05 can be followed spo radically on surface via old artisanal workings,

trenches and outcrops for a strike length of 800 m to the north and is part of an approximate 600 metre

corridor of mineralization and geophysical features in this same area. Mineralization in this area remains

open in all directions and is only covered by 600 m etres east to west of geophysics. Additional

geophysics is planned as follow up to the success of these holes.

TEN-17-07

Drill hole TEN 17-07 is the first drill hole ever d rilled into the Los Carneritos area, a larger 1.5 kilometre

by 1.0 kilometre area in the eastern end of the are a covered by geophysics (only 40% of the property

has been covered by ground surveyed magnetic and induced polarization geophysics). Los Carneritos is

located almost four kilometers to the east of the f urthest western drill hole from this program at El

Moreno (refer to surface drill hole location maps f or the property available on the Company's website

under the 'Projects' section 'Maps, Images and Phot ographs'). What is particularly intriguing about th is

hole was the abundance of vuggy silica and crystalline dickite clay in the core. Both vuggy silica and the

development of crystalline alteration clays are str ong indicators of the elevation for gold mineraliza tion

and degree of hydrothermal alteration, respectively within High Sulphidation systems. Mammoth will be

following up with at least two to three more drill holes testing other targets in the Carneritos areas as

part of the current drill program.
