EDM Provides Exploration Update and Plans for Its Eastville Prospect in Eastern Nova Scotia

Halifax, Nova Scotia--(Newsfile Corp. - March 4, 2024) - EDM Resources Inc. (TSXV: EDM) ("EDM" or the "Company") is pleased to provide the following update on the Company's current exploration activities at its Eastville base metals prospect in eastern Nova Scotia, Canada.

The group of licenses within its Eastville prospect (collectively herein referred to as the "Eastville Prospect") is comprised of 18 contiguous claims and is strategically located approximately 50 kilometres from the Company's flagship Scotia Mine property. Resourceful Geoscience Solutions Inc. ("RGS") of Halifax, Nova Scotia, Canada recently completed a program to relog 16 historical diamond drill holes located across the Company's claims, totalling 2,276m. This data, along with newly digitized historical assay certificates, were used to create mineralization and lithology models of the Eastville Prospect, as well as evaluate the potential opportunity for further drilling in the area.

KEY HIGHLIGHTS:

• Identified several correlated zones of Lead (Pb) and Zinc (Zn) mineralization from historical Eastville drillholes and that some of these zones remain open in multiple directions.
  
  
• Compilation of historical assay certificates has revealed historical intersections of 1.08% Pb+Zn over 66.5 metres from hole 224-23 and 1.45% Pb+Zn over 30.94 metres (m) from hole 224-7.
  
  
• New 3D mineralization and lithological models were created, based on relogging and historical data, to give new insights into the prospect and enhance the efficacy of exploration planning.
  
  
• Based on the positive results, there is opportunity for further expansion of the defined mineralization with additional drilling of up to 2,650 m.

"Given its strategic proximity to the Scotia Mine, we are excited about the exploration potential at the Eastville Prospect. The length of mineralization and the grades in holes 224-23 and 224-7, are consistent with the mineralization exposed in bedrock present in the river that cuts through the property," said Mr. Mark Haywood, President & CEO. "Advancing the exploration activities around the Scotia Mine deposit and those within close proximity, will continue to provide exploration upside with the potential to expand the Company's Mineral Resource base."

LAND PACKAGE OVERVIEW

EDM, thorough its 100% owned subsidiary, Scotia Mine Limited, possesses and maintains exploration licenses for several base metal prospects in Nova Scotia. The group of licenses within its Eastville prospect (collectively herein referred to as the "Prospect"), located approximately 50 kilometres from the Company's flagship Scotia Mine property, is comprised of 18 contiguous claims. The Prospect is a sediment-hosted strata-bound Lead-Zinc deposit, hosted within the Meguma Supergroup of meta-sedimentary rocks of Cambro-Ordovician age. The Lead-Zinc mineralization has been intersected in drilling over a strike length of approximately 3 kilometres within the area of the Company's exploration licenses, and mineralization occurs around the transition zone between the predominantly meta-greywacke Goldenville Group and the overlying argillaceous slates of the Halifax Group.

Table 1 Collar information of historical drillholes at the Eastville Prospect

Table 2 below highlights some of the composite intersections of historical assay data obtained through compilation of historical assay certificates. The table includes 66.5 m of 1.08% Zn+ Pb in hole 224-23, and 30.94m of 1.45% Zn + Pb from drillhole 224-7. Highlighted intercepts are those meeting a minimum grade of 1.0% Zn + Pb combined over a minimum drilled length of 5 m and no more than 5 consecutive meters below 0.5% Pb + Zn. Shorter including intervals meet a definition of at least 2.0% Zn + Pb over no less than 3 m drilled length and no more than 3 consecutive meters below 0.5% Zn + Pb. Based on 3-dimensional modelling true widths are believed to be approximately 90% of drilled lengths.

Table 2 Highlighted Diamond Drillhole Composite Results

Composite intercepts presented in Table 2 are calculated from a compilation of historical assay certificates from drilling programs by other operators in 1977 through 1979 and 1981 through 1983. Their work was completed to industry standards at the time, but it is not in keeping with what would be considered a modern standard with respect to the items of quality assurance and quality control. EDM Resources has not validated the results of these historical analyses through duplicate sampling.

LITHOLOGY MODEL

Using the 2023 relogging data combined with the digitized historical assays, a generalized 3D lithology model was created, as well as mineralization models. The lithology model includes the units of Slate, Calcareous Quartzite, and Quartzite. The slate unit defines the Halifax Group, and the quartzite lithology defines the Goldenville group. Historical and academic reports of the project describe a transition zone between the two groups which in this model was marked by a Calcareous Quartzite unit. Given the condition of the core, and density of drilling this was the highest resolution to which lithologies could be modelled at this time. The contacts between the units dip between 40 and 60 degrees to the Southeast.

MINERALIZATION MODEL

Sphalerite and Galena mineralization at Eastville is interpreted to be strata-bound, parallel to stratigraphy. As such, the contact between the Halifax group slates and Goldenville quartzites was used as an informing trend in all models of mineralization. A bivariate analysis of Zn and Pb values in historical analyses reveals that the two metals are linearly correlated and do not occur independent of each other. Therefore, mineralization models are based on a numerical value of %Zn + %Pb instead of creating separate models for the distribution of each metal. A subjective mineralization model was created by manually selecting and correlating mineralized drill intercepts exceeding a composite grade of 0.5% Zn + Pb from historical drill data. Unsampled intervals are assumed to be 0% Pb+Zn.

The extents of modelled domains in the mineralization model were limited to 50m from the furthest informing drillhole or halfway to the nearest constraining drillhole, whichever was less. A "constraining drillhole" was defined as an adjacent drillhole without a correlated intercept. The geometry of the modelled zones was informed by the orientation of the geological boundary between the Halifax group slates and Goldenville group quartzites. The resultant model is illustrated below in Figure 3.

Figure 4 illustrates a representative cross section of the relationship between geology and Zn+Pb mineralization at the Eastville project. Mineralization is concentrated around the contact of the Halifax and Goldenville groups and occurs on both sides of the contact.

POTENTIAL EXPLORATION DRILLING OPPORTUNITY

The Company believes, based on the positive results of this relogging program, that there is opportunity for further expansion of the defined mineralization with additional drilling. RGS has proposed a 2650-metre drilling concept which may be used to guide the planning of further exploration. The proposed concept is primarily based on 100-metre step outs both down dip and along strike of significant historical results. The primary objective of such a program would be to test the continuity of the historically identified mineralization.
