Royal Road Minerals (OTCQB: RRDMF) reported new reverse circulation drill results from the Hanash North prospect within the Jabal Sahabiyah project in southwestern Saudi Arabia. Highlight intercepts include 9m from 46m in hole HNRC009 grading 4.01% zinc, 34.3 g/t silver, 0.4 g/t gold and 0.3% copper (8.8% zinc equivalent), and 12m from 23m in HNRC010 at 3.13% zinc, 43.4 g/t silver, 0.2 g/t gold and 0.2% copper (7.1% zinc equivalent).

According to Royal Road Minerals, drilling has outlined shallow zinc‑silver‑rich polymetallic skarn mineralization over an interpreted strike length exceeding 350 meters, with all reported mineralization occurring above 65 meters downhole and remaining open along strike and down plunge. The project is advanced through Royal Road Arabia, a 50:50 joint venture with MIDU. Ongoing ground geophysics and planned RC and diamond drilling aim to test extensions and possible structural repetitions of the mineralized horizon.

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 Eq1)

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)

HNRC010 From 23m: 12m at 3.13% zinc 43.4g/t silver, 0.2g/t gold, 0.2% copper (7.1% Zinc Eq)

HNRC012 From 24m: 7m at 2.55% zinc 29.5g/t silver, 0.1g/t gold, 0.2% copper (5.5% Zinc Eq)

HNRC013 From 37m: 18m at 1.06% zinc 36.0g/t silver, 0.6g/t gold, 0.3% copper (6.4% Zinc Eq)

HNRC015 From 33m: 9m at 3.92% zinc 15.6g/t silver, 0.3% copper (5.9% Zinc Eq)

Geological Interpretation

Drilling at Hanash North has outlined a shallow, zinc-silver-rich polymetallic skarn system over more than 350 meters of strike. Mineralization remains open to the northeast to the southeast and down plunge and the causative intrusion has not yet been identified.

The mineralized horizon is hosted within calc-silicate rocks characterized by grossular garnet and diopside, with abundant pyrite and minor magnetite. Field mapping and drilling indicate that the host sequence and mineralized horizon have been affected by multiple phases of folding. This structural complexity provides potential for repetition of the mineralized horizon at depth, which remains untested by drilling.

Further Work

Ground geophysical surveys are currently underway at Hanash North to assist in defining the extent and geometry of the mineralized system and to identify potential extensions and repetitions of the mineralized horizon. Further RC and diamond drilling is planned to test extensions to the northeast and southeast, the interpreted structural repetitions at depth and the broader geological controls on mineralization.

"We are extremely pleased with the way Hanash North has developed," said Dr Tim Coughlin, President and CEO of Royal Road Minerals. "From a single historic drill hole reporting just 0.9 meters at 3.3% zinc, our team has systematically advanced Hanash North into a new, shallow polymetallic skarn discovery extending for more than 350 meters and remaining open along strike and down plunge. The widths, grades and near-surface nature of the mineralization are particularly encouraging. Ground geophysics is underway and further RC and diamond drilling will test extensions of the system and its potential repetition at depth."

Quality Assurance and Quality Control

Sample preparation and analyses are conducted according to standard industry procedures at certified laboratories.

RC and Analysis

Percussion-chip drillholes were sampled on 1 meter downhole intervals and passed through a 75-25% drill-rig mounted splitter. The 75% sample was placed in rows and analyzed for guidance on-site using a Vanta pXRF tool. The 25% sample was split 50-50% to produce analytical and retention samples of between 1 to 3kg. Samples for analysis were bagged in the field and sent to ALS Jeddah for analysis of gold by fire assay with an ICP-AES finish (method Gold-ICP22) and multi-elements by four acid digest ICP-MS (method ME-MS61QAQC). QAQC materials including CRMs, blanks and duplicates were inserted into the sample batch on a ratio of 1:14.

What exploration model and host rocks are described for Hanash North in the RRDMF update?

Hanash North hosts zinc-silver-rich polymetallic sulphide mineralization within a calc-silicate skarn horizon. According to Royal Road Minerals, the host rocks contain grossular garnet, diopside, abundant pyrite and minor magnetite, and have undergone multiple folding phases that may create untested repetitions at depth.

How does Royal Road Minerals calculate recovered gross metal value (RGMV) and zinc equivalent at Hanash North?

Recovered gross metal value is calculated using metal prices of $4,000/oz gold, $55/oz silver, $6.25/lb copper, $0.80/lb lead and $1.50/lb zinc with 90% recoveries. According to Royal Road Minerals, RGMV and zinc equivalent are exploration tools only, not economic value estimates.
