Royal Road Minerals expands zinc-silver discovery at Hanash North, Saudi Arabia

Intersects 9 meters at 4.01% zinc 34.3g/t silver, 0.4g/t gold, 0.3% copper (8.8% Zinc Equivalent)

Toronto, Ontario--(Newsfile Corp. - August 18, 2026) - Royal Road Minerals Limited (TSXV: RYR) (OTCQB: RRDMF) ( "Royal Road" or the "Company" ) is pleased to announce new reverse circulation ( "RC" ) drill results from the Hanash North prospect area within its Jabal Sahabiyah project in the Kingdom of Saudi Arabia.

Royal Road's exploration activities in Saudi Arabia are conducted through its local subsidiary, Royal Road Arabia Limited ( "RRA" ), a 50:50 joint venture with MIDU Company Limited ( "MIDU" ), a Jeddah-based investment group with interests across the mining, industrial, real estate, and utilities sectors.

The Jabal Sahabiyah Project is located in Asir Province, southwestern Saudi Arabia, and comprises three contiguous Exploration Licenses covering approximately 284 square kilometers (Figure 1). The area was first evaluated in the late 1970s by Riofinex, a subsidiary of Rio Tinto Zinc. Since being awarded the licenses, RRA has undertaken systematic exploration comprising geological mapping, drone-borne and ground geophysics, soil and auger geochemistry, trenching, rock-chip sampling and three phases of scout-style RC drilling (see press releases dated May 29, 2024; November 5, 2024; October 6, 2025; and February 26, 2026).

Hanash North

Mineralization at Hanash North (Figure 2) comprises shallow, zinc-silver-rich polymetallic sulphide mineralization hosted within a calc-silicate skarn horizon. Drilling has intersected mineralized widths of up to 20 meters over an interpreted strike length exceeding 350 meters (Figure 3), with mineralization remaining open along strike and down plunge. The horizon has been intersected from as little as 8 meters downhole and all mineralization reported from drilling to-date occurs above 65 meters downhole. A shallow zinc-oxide zone identified in several holes is interpreted to represent remobilized mineralization.

Drill intercepts were calculated using a minimum recovered gross metal value ("RGMV") of US$40 per tonne, (see Table1) allowing for a maximum of 5 meters of consecutive internal dilution below the RGMV threshold. RGMV was calculated using metal prices of US$4,000/oz gold, US$55/oz silver, US$6.25/lb copper, US$0.80/lb lead and US$1.50/lb zinc and assuming 90% recovery for all metals. RGMV is used solely as an exploration tool for defining reportable drill intercepts and does not represent an estimate of net smelter return or economic value.

Notable drilling intercepts include:

From previous campaigns:

HNRC003 From 20m: 12m at 2.85% zinc, 10.0g/t silver, 0.13% copper (3.91% Zinc Eq 1 )

HNRC005 From 61m: 9m at 4.36% zinc 67.8g/t silver, 0.6g/t gold, 0.2% copper (11.2% Zinc Eq)

From this drilling campaign:

HNRC009 From 46m: 9m at 4.01% zinc 34.3g/t silver, 0.4g/t gold, 0.3% copper (8.8% Zinc Eq)
