MAMMOTH INTERSECTS 58.2 METRES GRADING 0.8

GRAMS PER TONNE GOLD EQUIVALENT IN DIAMOND

DRILLING AT ITS TENORIBA PRECIOUS METAL

PROPERTY, MEXICO

Toronto, Canada (April 26, 2018) - Mammoth Resources 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. Mammoth is also

restating and supplementing results for hole number TEN 17-07 which had previously been announced

on April 12, 2018.

Results are for the two additional holes in the Los Carneritos area of the property; holes TEN 17-06

and TEN 17-08. These diamond drill holes at Los Car neritos extends the strike length of gold

mineralization on the property a total of almost fo ur kilometres within a High Sulphidation system

with mineralization open at least one kilometre both to the east and west of this four kilometre

trend where gold has been sampled on surface. Drill hole TEN 17-06 averaged 126.8 metres grading

0.52 grams per tonne (“g/t”) gold equivalent (“gold Eq”), including a higher gr ade intersection of 58.2

metres grading 0.80 g/t gold Eq of which 25 metres of this interval averaged 1.21 g/t gold Eq.

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 commented on these results stating : “We again

have intersected some very impressive lengths and g rades of gold mineralization at Tenoriba. In the

Carneritos area, holes TEN 17-06, 07 and 08 test different targets separated by 180 to as much as 750

metres one from another.

“Hole TEN 17-06 had the best intersection among the three holes drilled at the Carneritos area with an

impressive 126.8 metres grading 0.52 gram per tonne gold equivalent of which within this interval

assayed a lengthy 58.2 metre interval grading 0.80 grams per tonne gold equivalent.

"Hole TEN 17-08 is located 750 metres east of TEN 1 7-06 and although the hole had to be abandoned

due to technical difficulties at 102 metres of a pl anned 200 metres to test the target at this locatio n, the

portion of the core recovered assayed 14.9 metres grading 0.62 grams per tonne gold equivalent.

“We believe the potential to step-out and extend m ineralization from any of these holes is high based

on surface geology and gold in samples collected in the vicinity of these holes. The Carneritos area i s

on the eastern end of a four kilometre approximate east-west oriented trend of gold with minor silver

mineralization at Tenoriba tested in this drill pro gram and represents an approximate one kilometer

extension to the prior, eastern-most drilling on the property."

TEN-17-06

Drill hole TEN 17-06 is located 160 metres (“m”) no rth and 100 m west of hole TEN 17-07 which

assayed 0.28 g/t gold Eq. over 42.0 m and 0.36 g/t gold Eq over 12.5 m. Hole TEN 17-06 was collared

near Carneritos channel T3, which assayed 1.07 g/t gold Eq over 15.7 m. Mineralization in this hole is

within a fractured and occasionally brecciated and vuggy textured crystalline lithic tuff with presence of

remnant alteration clays and from 3 to 5% pyrite in numerous shallow to high angle micro. TEN 17-06

has a 126.8 m interval assay 0.52 g/t gold Eq of wh ich within this interval there was a 58.2 m section

assaying 0.8 g/t gold Eq. This intersection remains open in all directions. Additional geophysics is

planned as follow up to the success of the holes dr illed in the Los Carneritos area with the survey to

extend east of the current geophysics survey where gold has been sampled in various outcrops. Please

hole locations and drill sections.

TEN-17-08

Drill hole TEN 17-08 is located 750 m from the collar of hole TEN 17-06 (400 m west and 400 m south)

and 700 m (500 m west and 200 m south) of hole TEN 17-07 which assayed 0.28 g/t gold Eq. over 42.0

m and 0.36 g/t gold Eq over 12.5 m. Hole TEN 17-08 was abandoned early and shallower than originally

planned due to technical difficulties and as such failed to fully test the geophysical feature at this target

area, however did still report a 14.9 m interval assaying 0.62 g/t gold Eq. Mineralization occurred within

fractured iron oxide stained weak to moderately sil icified and brecciated feldspathic phyric tuff.

Mammoth expects to return to this area in the futur e to attempt another hole at a slightly different

orientation to further test this target and attempt to extend the mineralization encountered at this

location. Please refer to the Company's website und er the 'Projects' section; 'Maps, Images and

Photographs’ for a drill hole locations and drill sections.
