PPX Samples 1.4m Grading 52.2 gpt Au and 1.1 m Grading 1,122 gpt Ag

Underground at Igor

Vancouver, British Columbia – September 25, 2017 – PPX Mining Corp. (the "Company" or “PPX”)

is pleased to announce results from 84 channel samples collected underground at Mina Callanquitas as

part of the Company’s test mining and bulk sampling program at its Igor Project. The samples wer e

collected from working faces along the Callanquitas structure on three separate levels of mine workings.

Significant results are summarized below:

• Level 3440N: Twenty channel samples collected over a continuous strike length of 45 metres

averaged 15.7 gpt Au and 122 gpt Ag and ranged in grade from 6.6 gpt to 52.2 gpt Au and from 3

to 950 gpt Ag (9154285 to 9154330 North on the mine grid). The Callanquitas structure ranged

from 1.2 to 2.5 metres in true thickness over this strike length (please see plan view maps for all

levels posted on the Company’s website) . Twenty channel samples collected south of the

proceeding sample set averaged 13.3 gpt Au and 119 gpt Ag ranging in grade from 1.8 to 30.7 gpt

Au and from 3 to 664 gpt Ag (9154223 to 9154285N). The combined sample sets document

continuous gold and silver mineralization over a strike length of 90 metres along the Callanquitas

structure averaging 14.5 gpt Au and 100 gpt Ag over widths ranging from 0.7 to 2.5 metres. The

channel samples, combined with bulk samples that mimic actual mining conditions, are designed

to validate the resource block model. The nearest drill hole intercept to this portion of the

Callanquitas structure is CA-12-68, which cut 1.0 metre grading 4.7 gpt Au and 18.2 gpt Ag.

• Sublevel Nv 2b (3419): Twenty-two channel samples collected over a continuous strike length

of 45 metres averaged 18.7 gpt Au and 80 gpt Ag and ranged in grade from 4.1 to 50.6 gpt Au

and from 0.5 to 329 gpt Ag (9154285 to 9154330N). The Callanquitas structure ranged from 0.5

to 1.5 metres in true thickness over this strike length. These samples are 20 metres below the high

grade samples collected on the 3440 level, demonstrating vertical continuity of high grade gold

mineralization in the Callanquitas structure. A continuous fifteen metre segment of high grade

gold and silver mineralization within the 45 metre segment described above contained an average

grade of 34.1 gpt Au and 120 gpt Ag based on seven channel samples. These results outline a

very high grade, almost vertically raking, precious metal mineralized shoot almost 1.3 metres in

width. This geometry would have been particularly difficult to identify from surface drilling. The

nearest drill hole to these samples on Sublevel Nv 2b was CA -12-63, which cut 0.5 metres

grading 7.2 gpt Au and 7.4 gpt Ag.

• Level 3390N: Twenty-two samples collected over a continuous strike length of 35 metres

averaged 8.8 gpt Au and 152 gpt Ag and ranged in grade from 3.0 to 17.9 gpt Au and from 2 to

1,122 gpt Ag (9154175 to 9154210N). The Callanquitas structure ranged from 0.4 to 2.5 metres

in true thickness over this strike length. It should be noted that the gold and silver mineralization

seen on this level is located south of the high grade zone sample on Sublevel Nv 2b and the 3440

level. The test mining plan anticipates advancing the 3390 level to a position under the

aforementioned high grade zone in the coming months. The nearest drill hole to the channel

samples on the 3390 level was CA-12-66, which cut 0.5 metres grading 1.26 gpt Au and 352 gpt

Ag.

The consistent and high grade tenor of gold and silver mineralization seen in the channel samples

suggests that precious metal distribution within the Callanquitas structure and hydrothermal system is

regular, predictable, and in general, higher grade than seen in drilling. While this is encouraging, The

Company recognizes that the test mining and bulk sampling program is at an early stage and the pattern of

grade distribution will have to be verified by further bulk sampling and channel sam pling. Plan maps

depicting the results of the channel sampling program are available on the Company’s website including a

long section that allows the channel samples to be accurately located with respect to mine workings.

Brian J. Maher, President and CEO of PPX Mining commented: “We are pleased with results of our

channel sampling program at Mina Callanquitas. The distinct, high grade, “clavos” that have been

identified by the underground channel sampling and geologic mapping program, are an encouraging

development. While the presence of these high grade zones was not unexpected, the apparent high-angle

rake of these zones make them challenging to identify in surface drilling. Our geologists will focus on

better understanding the controls to this high grade gold and silver mineralization so that we can more

effectively explore for this high grade style of mineralization, both within the existing resource and

elsewhere on the Igor Project”

Channel sampling protocols and QA/QC: PPX Mining geologists collect channel samples underground

on each working face prior to advancing the excavation. Samples are collected orthogonal to the structure

edge or boundary and do not exceed 2.0 metres in length. Channels are broken at obvious geologic

boundaries to correctly separate rock types, mineralization styles and hydrothermal alteration

assemblages. The samples are collected by cutting a channel approximately 2.5 cm deep by 25 cm wide

along a line painted on the face by the mine geologist. Sample weight is typically 1.5 to 2.5 kg. Samples

are sealed, labeled and stored in a secure area prior to shipment to a qualified assay laboratory. Gold and

silver analyses are conducted by the fire assay method with a CN leach. Blanks and standards are

inserted approximately every 15 samples; duplicate channel samples are included at the same intervals.

Duplicate fire assays for approximately every 30 samples are sent to a second assay laboratory for umpire

analysis.

About PPX Mining Corp: PPX Mining Corp. (TSX.V: PPX.V, SSE: PPX, BVL: PPX) is a Canadian-

based exploration and development company with assets in northern Peru. Igor, the Company’s 100% -

owned flagship gold and silver project, is located in the prolific Northern Peru gold belt in eastern La

Libertad Department. PPX is pursuing a two-prong strategy to further develop and explore the Igor

Project. The Company has begun work on its underground test mining and bulk sampling program which

is designed to upgrade the resource estimate and generate data to evaluate the possibility of future mine

development at Igor through the PFS process. To date, PPX has processed over 3,516 tonnes of bulk

sample averaging 8.17 gpt gold. Simultaneously, PPX is accelerating its exploration program at Igor in

order to fully evaluate the resource potential of the entire Igor project area. The Callanquitas Structure is

open along strike and at depth. Parallel structures are unexplored and, coupled with the Domo and

Tesoros areas; these drill targets highlight the exploration potential at Igor. Evaluating mine development

alternatives in parallel with exploration drilling provide dual catalysts for growth and increasing

shareholder value.

Previous exploration on the Callanquitas Structure discovered a significant Inferred gold and silver

resource: 7,189,000 tonnes grading 1.94 gpt gold and 71.8 gpt silver containing 448,500 ounces of gold

and 16,600,000 ounces of silver at a cutoff grade of 1.5 gpt gold equivalent. Included within this resource

estimate is a higher grade zone consisting of 2,730,000 tonnes grading 2.73 gpt gold and 119.1 gpt silver

containing 239,400 ounces of gold and 10,500,000 ounces of silver using a 3.0 gpt gold equivalent cutoff

grade (Please see Technical Report, amended September 27, 2013, available on the Company’s website or

SEDAR). Mineral resources are not mineral reserves and do not have demonstrated economic viability.

There is no certainty that all or any part of the mineral resource will be converted into mineral reserves.
