MILLROCK PROVIDES UPDATE OF EXPLORATION ACTIVITY

VANCOUVER, BRITISH COLUMBIA, July 18, 2018 - Millrock Resources Inc. (TSX-V: MRO,

OTCQX: MLRKF) ("Millrock") is pleased to provide the following exploration update. Active

partner-funded projects and projects that are under evaluation by potential partners are

reviewed below. Anticipated partner-funded exploration for 2018 is valued at approximately

US$5 million. The approved exploration budgets include approximately 10,000 meters of drilling

at three different projects.

Gregory Beischer, Millrock President & CEO commented: “We have plenty of potential catalysts

to improve the Millrock share price through the discovery of valuable resources. Millrock

continues to be a prolific generator of new projects that attract funding of major and junior

companies alike.”

EXPLORATION UPDATE: MID-POINT 2018

ALASKA

Alaska Range Project (copper-gold-silver skarn, copper-gold porphyry). In 2017, Millrock

sold its Stellar Project to ASX listed PolarX Mining Ltd. (ASX: PXX) (“PolarX”). PolarX owned

adjacent lands, and combined, the two blocks of claims form what is now called the Alaska

Range Project. The claims protect over 35 kilometers of copper anomalism with skarn,

porphyry-style and volcanogenic mineralization indicated. PolarX has recently raised ~AUD $2.4

million and authorized a budget of US$2.5 million for further drilling. As recently announced

here, 23 holes are planned in the current program. Millrock continues as the exploration

operator. The drilling program is well underway. Millrock owns 9.76% of the issued and

outstanding shares of PolarX, which at recent market prices has a value of approximately

AUD$2.2 million. Millrock also holds a royalty on portions of the property and is entitled to

certain milestone payments.

Liberty Bell Project (gold). This gold project is under option to joint venture with Kinross,

whereby Kinross can earn a 70% interest. Millrock is the exploration operator and is entitled to

management fees, advanced minimum royalty payments, and a net smelter royalty. A program

consisting of an induced polarization geophysical survey and geological mapping is planned for

August-September. Drilling is anticipated in 2019.

Goodpaster Project (intrusion related vein gold). Millrock owns (or has an option on) seven

individual claim blocks in this district of Alaska near and adjacent to the Pogo Mine – a

successful gold mine operated by Sumitomo. The Company has developed a compelling target

at the West Pogo portion of this project. Sumitomo has recently announced a gold discovery to

the east of the Millrock – Sumitomo claim boundary. Two major gold companies and a junior are

considering a partnership on the Millrock claims.

SONORA, MEXICO

La Navidad (gold). This project targets large-tonnage gold deposits. Centerra Gold is the

funding partner and can earn up to an 80% interest. Centerra has funded a comprehensive,

systematic geological-geophysical-geochemical exploration program that has been ongoing

since 2017. Three main target areas have been delineated. A 2,900-meter drilling program has

recently been completed to test the Cobre and Crossover targets. Complete results are

anticipated in early August.

El Picacho (gold). The target at this project is an orogenic gold deposit similar to the San

Francisco mine, which is approximately 15 kilometers to the east in a very similar geological

setting. Centerra Gold is also funding this project and can earn 80% interest. This has been a

very active project in the first half of 2018. Drill targets are emerging from the exploration work.

Centerra has authorized a drilling program to begin later in the summer.

Guadalcazar (silver-lead, zinc skarn). This project hosts a high-grade silver-zinc-lead skarn

deposit with good drill intersections and historic mine workings. There is potential to expand

upon the known deposit. Millrock has received an offer to form an option to purchase

agreement.

Batamote (copper porphyry). This project targets a porphyry in the Cananea – Caridad

trend. There are some good geological signs of a porphyry copper deposit from prior, historic

work. A major copper company is currently evaluating the project.

Los Cuarentas (low sulfidation epithermal gold-silver). Millrock has acquired an option to

purchase a key internal claim block called Santa Rosalia. Drill targets have been developed and

drilling permits are in place. Numerous potential partner companies are evaluating this project.

NEW MEXICO

Lordsburgh (lithium brine). Millrock recently staked claims over a playa in southeastern New

Mexico. The claims cover the deepest part of a sedimentary basin that has the potential for the

accumulation and entrapment of lithium bearing brines. Millrock has sold the claims to Xinda

International Corp. (“Xinda”) (OTC: XNDA). Consideration was US$50,000 (payable upon initial

financing) plus 19.9% of the issued and outstanding Xinda shares. In the event that US$5

million is spent on the claims or the surrounding area of interest by Xinda, Millrock will be issued

the number of Xinda shares needed to restore 19.9% ownership at that time (assuming that

Millrock has not sold any of the initial share payment). Millrock will also be entitled to a 3%

Gross Sales Royalty in the event of lithium production. The project was brought to Millrock by a

geologist that was entitled to a finder’s fee. The finder agreement has been assumed by Xinda.

Antelope Pass (Carlin-style or intrusion-related gold). Over the past several months Millrock

has staked claims covering an extensive hydrothermal alteration zone intermittently exposed

over at least 10 kilometers. Geological features at Antelope Pass have similarities to the highly

productive Carlin Trend of Nevada. Potential partner companies are evaluating this project.

Red Basin (roll-front uranium). For several years Millrock has held an option agreement on

claims covering a roll-front style uranium deposit discovered in the 1970s by Gulf Minerals.

Recently, Millrock converted the option agreement to a finder’s agreement and took possession

of the claims. Finder’s fees will be paid to the finder in the event that Millrock secures a funding

partner for the project.

BRITISH COLUMBIA

Todd Creek, Oweegeee Dome, Willoughby (gold and base metals). Millrock acquired three

projects in the Golden Triangle District in late 2015. Two of these projects have been optioned

to Sojourn Exploration Inc. (“Sojourn”) (TSX-V: SOJ). A proposed transaction would have

Millrock sell all three projects to Sojourn, and a new technical and management team would

take over, bringing in four of their own projects. A Letter of Intent has been signed. If the deal is

completed, Millrock will own 19.9% of a new top-flight BC project generator and will hold

royalties on its three properties.
