Val-d'Or Mining Exploration Update

| JULY 10, 2018

Val-d'Or, Québec, July 10, 2018 — Val-d'Or Mining Corporation ("Val-d'Or Mining" or the "Company) (TSX-V:MZZ) is pleased to announce an update on its exploration activities located in the Abitibi Greenstone Belt.

Initial ground exploration work is planned on three (3) priority gold projects located in NW Québec and NE Ontario, including line cutting (grid establishment), geophysical surveying (ground magnetic and induced polarization), geological/structural mapping, sampling and outcrop stripping. The primary objective of this work is to resolve drill targets for Fall 2018 campaigns.

Oregon Prospect – Val-d'Or, Québec

The Oregon Prospect covers an elongated granodiorite intrusion that dips to the northeast and lies along a northwest southeast axis. The granodiorite part of the property hosts the historic Oregon Showing (Corps Minéralisé 32/C05-0011. MRNF SIGEOM).  This mineral occurrence occurs within a fracture zone that hosts a series of parallel quartz stringers mineralized with pyrite. It has been traced out by previous exploration programs over a strike length of one hundred and twenty metres.

An assay result of 1.980 opt Au from a 3 foot long channel sample within the showing area was taken in 1985 (GM 42404). DDH 80-7, a 60.4 metre vertical hole that was drilled into the showing in 1980, encountered a 0.4 metre intersection of bleached rock that carried 0.10 opt Au (GM 36410).

In 2010 and 2011, Golden Valley Mines sampled the historic Oregon Showing pit.  The Oregon Showing was first discovered in 1935 (GM 66328). A sample of granodiorite blast rock containing quartz and trace pyrite carried 5.76 g/t Au. A grab sample from the adjacent granodiorite outcrop that contained rusty quartz with up to 4% pyrite returned an assay value of 20.4 g/t Au.

In 2014, channel sample 423312 was cut into a quartz vein located approximately 75 metres west of the Oregon Showing. The 0.80 metre long sample carried 1.85 g/t Au. Other channel samples cut into the granodiorite surrounding the Oregon Showing were anomalous in gold with the highest assayed gold value being 6.19 g/t Au.

Approximately 1.6 kilometres to the northwest there are a series of historic trenches within the granodiorite intrusion. Grab samples of fly rock taken in 1985 returned gold values of 2.15 opt Au and 0.423 opt Au (GM 42404).

A sample of blast rock from one of these trenches was collected by Golden Valley Mines in 2011. This grab sample of altered granodiorite with trace pyrite carried 2.64 g/t Au (GM 66328).

The primary metallogenic target at the Oregon Prospect is an intrusive-hosted, bulk tonnage gold deposit.

Magoma Prospect – Val-d'Or, Québec

The property overlies the felsic volcanic rocks of the Hunter Mine Group and is situated midway between the Rouyn-Noranda and Normetal mining camps. The Magoma gold showing occurs within an extensive network of quartz veins controlled by intense shearing that cuts through tuffacaeous and porphyritic units of rhyolite. This geological setting is proximal to a fault splay from the regional gold bearing Macamic Deformation Corridor that passes through the northeast part of the property.

In 1950, Preston East Dome Mines Ltd. discovered three gold occurrences within this extensive quartz vein system (GM 10303).

In 1963, Magoma Mines Ltd. drilled a closely spaced pattern of eight vertical drillholes into the Preston East Dome #1 showing (GM 14923). Significant gold values ranging from 0.17 to 2.80 opt Au over varying widths of between 2.4 to 6.9 feet were encountered in some of these drillholes.

An old core dump of small diameter core is located several hundred feet southeast of the #1 showing. Three grab samples of quartz material from this abandoned core pile taken in 1973 by Noranda Exploration Company Ltd. carried encouraging metal values. One sample assayed 1.51 opt Au with 0.81 opt Ag while another carried 0.47 opt Au and the third assayed 0.38 opt Au with 0.09 opt Ag (GM 29754).

In 2010, Golden Valley Mines completed a reconnaissance prospecting program over parts of the present Magoma Prospect. The three (3) Preston Dome Mines Ltd. showings were located and sampled as well as the old core dump. A grab sample from a quartz vein at the main or #1 showing carried 0.604 g/t Au (GM 65543).

In 2014, Golden Valley Mines carried out a more comprehensive sampling of the main or #1 showing.  Grab sample 423325 carried 2.54 g/t Au and sample 423328 of blast rock from the showing carried 1.635 g/t Au

The primary metallogenic target at the Magoma Prospect is an orogenic gold deposit spatially related to a deformation zone hosted in altered and mineralized metavolcanic rocks.

Baden Prospect – Matachewan, Ontario

The gold showings on the property occur in quartz veins associated with mineralized syenite porphyry dikes. The showings are located approximately thirteen kilometres north-northwest of Young Davidson Mine (Alamos Gold) that occur within a stockwork of quartz veinlets and narrow quartz veins, rarely greater than a few centimetres thick that are within a broader halo of disseminated pyrite and potassic alteration.

In 1937, the No. 2 Vein or discovery vein (Fondewa Gold Mines) was extensively trenched. Four grab samples of quartz from this vein are reported on in dollar values based on gold at $35.00 an ounce. They are listed as follows: $10.50, $3.50, $4.90 and $2.80 (Robson, 1938; KL 2155).

Also in 1937, the No. 2 Vein was cut  at  shallow  depths  by  seven  drill  holes along  a  strike  length  of  500  feet  with  the  following  results (McCannell, 1976 AFRO 63.3327).

DH 2 (1937) / 0.18 opt Au over 4 feet
DH 5 (1937) / 0.07 opt Au over 3 feet
DH 6 (1937) / 0.35 opt Au over 1.58 feet
DH 7 (1937) / 0.38 opt Au over 4 feet
DH 8 (1937) / 0.11 opt Au over 5.25 feet
DH 10 (1937) / 0.31 opt Au over 2.5 feet

In 1976, diamond drilling was carried out on the No. 7 Vein (Manitou Gold Mines) located about 250 metres north-northwest of the No. 2 vein. The logs describe the geology as being made up of feldspar porphyry, felsite and andesite. Highly anomalous gold values were encountered over narrow widths in some of the drillholes (McCannell, 1976, AFRO 63.3327).

DH 4 (1976) / 0.175 opt over 6.0 feet and 0.44 opt Au over 0.6 feet
DH 7 (1976) / 2.26 opt Au over 1.6 feet & 0.545 opt Au over 0.6 feet
DH 8 (1976) / 3.23 opt Au over 2.0 feet
DH 10 (1976) / 3.79 opt Au over 0.8 feet

The Quilty Showing is located 600 metres southwest of the No. 2 Vein. At this location an old trench exposes white quartz veins containing 1-2 % pyrite cubes up to 5 mm across as well as ankerite veins. The metavolcanic host rock is silicified near the veins (Kresz, 1993; OFR 5874).  A channel sample from the trench was said to have assayed 0.45 opt Au (Lovell, 1967; GR 51).

The J.E. McVittie (French Vein) Showing consists of a quartz vein in the contact zone between massive volcanic rocks (possibly tuffs) on the west and syenite porphyry on the east. A grab sample of red syenite porphyry containing quartz stringers gave an assay of 0.14 opt Au. A loose sample of vein quartz containing a small amount of chalcopyrite and pyrite gave an assay of 8.41 opt Au and 9.79 opt Ag (Lovell, 1967; GR51).

In 1973, Ronda Copper Mines Ltd. drilled DDH's 73-01 and 73-02 under the J.E. McVittie (French Vein) Showing. DDH 73-02 intersected 0.475 opt Au over 3 feet (Szetu and Ogden, 1978; AFRO 63.3554).

Prospecting of the No.2 vein by Golden Valley Mines in 2013 was successful in collecting many grab samples that were highly anomalous in gold. The four best assay results were 31.90 g/t Au, 15.95 g/t Au, 15.75 g/t Au and 12.12 g/t Au.

Sampling of the Quilty Showing by Golden Valley Mines in 2013 returned assay results of 6.66 g/t Au, 2.17 g/t Au and 1.13 g/t Au.
