Gold Reserves and Deposits in the Philippines

As of 2026-08-30 · Updated 2026-08-30 · Section: Mineral Resources · 日本語版

This field is a textbook case of "a number taking on a life of its own." The claim that "the Philippines is the world's second-largest gold reserve holder" does not match any official statistics. The Philippines is not listed individually in the USGS gold reserves table (it falls within the "other countries" category totaling 11,000 tonnes). At the same time, gold has been the Philippines' largest metallic mineral commodity since 2024, and in Q1 2026 gold accounted for roughly 65% of metallic mineral production value (MGB). Because of the gold price surge of 2025–2026, a strange situation persists in which "production volume is falling while production value and reserve valuations are surging."

1. First, let's pin down the terminology — reserves / resources / endowment

注 Mixing up these three terms breaks the entire discussion. The Japanese word "埋蔵量" (maizōryō) gets translated into English as both "reserves" and "resources," so it is essential to always check the original-language term.

注 Inferred resources cannot be converted directly into reserves under JORC, PMRC, or NI 43-101. It is not unusual for a project's "resources of X billion tonnes" figure to be mostly Inferred.

注 Reserves are not "the amount sitting in the ground" but "the amount that can be profitably mined at today's price." That is why reserves rise when the gold price rises and fall when it falls. The Philippines' 2025–2026 figures are strongly affected by this effect.

Differences in reporting standards — always check which standard a figure follows

Under PMRC, a signature from an ACP (Accredited Competent Person) is required, and an ACP must be a member of PSEM, GSP, or SMEP. The practical experience required differs between an ACP who estimates resources and one who estimates reserves (ACP-Geologist / ACP-Mining Engineer).

2. Fact-checking the claims that have circulated

2-1. "The Philippines is the world's second-largest gold reserve holder"

Conclusion: "world's second-largest gold reserves" does not hold up whether measured by central bank reserves or by official mineral-deposit statistics. Even if the claim is meant to describe geological endowment, no primary source substantiating it could be found.

2-2. "World's 5th most mineralized country" / "3rd in gold, 4th in copper, 5th in nickel, 6th in chromite"

• This stock phrase also appears on MGB regional-office sites and in trade press, but Thermo Fisher's mining blog attributes this ranking to the "Australian Trade and Investment Commission (Austrade)." No MGB-originated ranking study could be confirmed.
• 注 The MGB regional-office article is a reprint of a Philstar contributed piece, and it cites MGB statistics only for the employment and production-value figures — it does not give a source for the ranking itself.
• The primary source is unconfirmed. When citing it, one should note it as "a ranking said to originate from Austrade, of unclear origin."

2-3. "2nd in the world for mineral endowment per unit area"

• The source could not be identified — unconfirmed.
• 注 This is often confused with something else: the Fraser Institute does not publish such an indicator. That institute's annual mining company survey is perception-based, with an investment-attractiveness index built from 60% geological-potential assessment plus 40% policy assessment. In fact, the Philippines scores poorly — ranked 72nd out of 86 jurisdictions (investment attractiveness) in the 2023 survey.

2-4. "$1 trillion / $1.4 trillion in undeveloped mineral resources"

3. The real numbers, from official statistics

3-1. USGS Mineral Commodity Summaries 2026 (published February 6, 2026; v1.1 in March 2026; DOI: 10.3133/mcs2026)

注 The full-text PDF was inaccessible at the time of research, so the figures below are drawn from multiple secondary outlets (mining.com.au, Visual Capitalist, Investing News, StatRanker) that agree with one another. Re-verification against the primary source is recommended.

World gold reserves (estimated as of year-end 2025): total 66,000 tonnes (revised upward from 64,000 tonnes in the prior year's edition)

The Philippines is not among the 13 individually listed countries. It is buried inside the "other countries, 11,000 tonnes" line. 注 The fact that USGS does not list it individually is the most direct evidence that, on a global scale, its deposits are not outstandingly large.

World gold mine production (2025 estimate): China 380 t, Russia 310 t, Australia 280 t, Canada 200 t, US 160 t, Ghana 150 t, Mexico 140 t, Kazakhstan/Uzbekistan 130 t each, Peru 110 t, Indonesia/South Africa 90 t each, Brazil 80 t. The top 3 countries total 970 tonnes, said to represent about 29.4% of the world total, putting the world total at roughly 3,300 tonnes. The Philippines' annual output of 20–29 tonnes is under 1% of the world total.

3-2. PSA's "Mineral Accounts of the Philippines"

This is the only systematic gold "reserves" statistic produced by the Philippine government. It follows the framework of the UN's System of Environmental-Economic Accounting (SEEA).

注 Here, Class A reserves means "commercially recoverable mineral resources confirmed to be economically viable under a specific development plan or operation" — equivalent to reserves.

Volume fell while value rose 41.6%. This is a direct consequence of the gold price surge. 注 Do not read a headline about "surging mineral assets" as meaning the reserves themselves grew.

注 PSA's figures exclude BARMM (the Bangsamoro Autonomous Region in Muslim Mindanao) due to data constraints. 注 Also, the 2024 figure was originally announced as 357.11 thousand kg / ₱481.45 billion and was revised upward the following year. When comparing figures across years, be sure to use the revised, consistent values.

3-3. Production statistics from MGB

In Q1 2026, gold accounted for roughly 65% of metallic mineral production value. The top producer for the quarter was the Masbate gold mine (Filminera Resources + Philippine Gold Processing & Refining), at 1,646 kg / ₱14.75 billion.

注 (Corrected 2026-08-25 through cross-checking) ₱316.29 billion is not "metallic mineral production value" but rather "total mining production value (including non-metallic)." An earlier version of this document had entered this figure in the table as the metallic value, but all five related documents in the cluster ("Mining and Nickel" Chapter 1 / "Comprehensive Review of Subsurface Resources" 1-1 / "Copper and Other Metal Resources" 2-2 / "Non-Metallic Minerals and Aggregates" 2.2, among others) treat it as total mining production value. This is also arithmetically consistent: if the 2023 gold value of ₱106.64 billion was "42.82% of total metallic value" (per the field "Major Gold Mines and Production," 1-1), total metallic value would be ₱249.0 billion; metallic value for Jan–Sep 2025 was ₱219.74 billion (versus ₱191.42 billion in the same period the year before), implying full-year 2024 metallic value on the order of ₱252.9 billion. At ₱316.29 billion, gold's share would be only about 40%, which does not match the description that "in 2024 gold accounted for roughly half of metallic value and ranked first." 注 That said, MGB has not publicly clarified the difference between these two definitions, and primary confirmation of the ₱252.9 billion figure remains incomplete (unconfirmed). When citing this figure, always specify whether it refers to metallic minerals only or to mining overall including non-metallic.

MGB designates roughly 9 million hectares of national territory as "high mineralization potential areas" (this figure was also cited in Executive Order No. 122 of August 21, 2026). 注 This is an endowment figure — it is neither reserves nor resources.

4. Geological background — why does the Philippines have gold?

The Philippine archipelago is part of the Pacific Ring of Fire, sitting at the collision zone between the Eurasian Plate and the Philippine Sea Plate. It has a globally unusual structure as a "double subduction" island arc, with subduction zones on both sides — the Manila Trench to the west and the Philippine Trench to the east.

The magmatic activity generated by this subduction creates gold and copper deposits.

Porphyry and epithermal systems are "the deep and shallow parts of the same hydrothermal system." In the Mankayan mineral district, the Lepanto high-sulfidation epithermal deposit and the porphyry copper-gold deposit beneath it, Far Southeast, have been shown to have formed simultaneously within a geologically very short span — 300,000 years or less (Arribas et al., 1995, published in the journal Geology). This is cited as a classic case study in global economic geology.

The porphyry copper deposits of the West Luzon arc are attributed to magmatic activity associated with the eastward subduction of the Eurasian Plate at the Manila Trench since the Late Oligocene (Imai et al.). A comprehensive academic review can be found in the special issue "Philippine Porphyry and Epithermal Deposits" in Economic Geology, Vol. 106, No. 8 (2011).

5. Major mineral districts

注 Be cautious of materials that discuss "Palawan's gold deposits." Palawan's mining is almost entirely nickel (Rio Tuba, Ipilan, Berong, etc.), and it is not a major gold-producing area. Specific resource data for gold mineralization signs such as Ulugan Bay could not be confirmed — unconfirmed.

6. Major operating gold mines (as of August 2026)

7. Major undeveloped deposits — where the substance of "Philippine gold" actually lies

注 Simply adding up the gold figures for the undeveloped deposits above yields roughly 30 million ounces (about 930 tonnes), but these are mostly resources, not reserves. This is a different concept from PSA's Class A reserve figure of 371 tonnes, so the two should not be summed or compared.

8. Impact of the gold price surge (2025–2026)

Four effects of the price surge on the Philippines

1. Production volume falls, but production value rises. In Q1 2026, gold production volume fell 24.7% while production value rose 31.2% (MGB). 注One needs to check what's actually behind headlines saying "mining is growing."
2. Reserve valuations jump. PSA's Class A gold reserve value rose 41.6% in 2025 even as volume fell 4.9%.
3. Reserves themselves can grow. This is because low-grade ore becomes economical to mine. Padcal's life extension was explained as premised on "the gold price staying above US$2,000/oz." 注However, OceanaGold's own reserve price assumption is US$2,200/oz — less than half the prevailing price — because companies use conservative assumptions.
4. Central bank gold reserves are ballooning. BSP's gold holdings stood at US$18.58 billion at end-2025 and US$20.67 billion in January 2026. Gold's share of total reserves (GIR, US$110.9 billion at end-2025) is about 17%, sharply up from roughly 10% in 2024, and exceeding BSP's own target range of 8–12%. Governor Remolona has said "if the portfolio share gets too large, we will sell."

9. Small-scale mining (ASGM) and the BSP purchasing system

A significant portion of the Philippines' gold output comes from artisanal and small-scale gold mining (ASGM), but this is not fully reflected in official statistics.

注 The English phrase "Philippines gold reserves" can, depending on context, refer to either (a) BSP's monetary gold reserves or (b) underground mineral reserves. This ambiguity is the seedbed of the "world's second-largest" myth.

10. The 2025–2026 policy environment

注 EO 122's focus is on "critical minerals" — gold is not its primary target. Gold is generally not classified as a "critical mineral" for economic-security purposes, so this policy's direct benefit to gold should be regarded as limited.

11. Points that are easy to get wrong

1. 注 "The Philippines is the world's 2nd-largest gold reserve holder" does not match any official statistic. It should not be cited.
2. 注 The Philippines is not listed individually in the USGS gold reserves table. It is folded into "other countries."
3. 注 Central bank gold reserves and geological mineral reserves are different things. The shared English word "reserves" is the source of the confusion.
4. 注 The "$1 trillion / $1.4 trillion of undeveloped minerals" figure is itself acknowledged by MGB as "just a rough estimate." The underlying US$840 billion figure dates from 2012.
5. 注 "World's 5th most mineralized country" is said to originate from Austrade, not from an MGB study. The primary source is unconfirmed.
6. 注 "2nd in the world for endowment per unit area" is of unconfirmed origin. The Fraser Institute has no such indicator.
7. 注 Do not add up the "resources" of undeveloped deposits and call the total "reserves." Most of it is Inferred.
8. 注 Corporate reserves are calculated using conservative gold price assumptions. OceanaGold uses US$2,200/oz, versus a prevailing price around US$4,600.
9. 注 Do not read growth in production value as growth in production volume. In Q1 2026, volume was −24.7% while value was +31.2%.
10. 注 PSA's mineral accounts exclude BARMM, and prior-year figures are frequently revised.
11. 注 Palawan is not a major gold-producing region (it is dominated by nickel), and it has been under a 50-year mining moratorium since 2025.
12. 注 Many of the Philippines' large gold deposits are "gold as a byproduct of copper." Tampakan, King-king, Silangan, FSE, Padcal, and Didipio are all copper-gold deposits, so they are subject to copper price and market trends.
